Introduction

This AP-51xx Product Reference Guide contains setup and advanced configuration instructions for both the AP-5131 and AP-5181 model access points. Both the AP-5131 and AP-5181 model access points share the same Web UI, CLI and MIB interfaces. There are no differences in how the devices are configured using the instructions within this guide, even though the Web UI displays AP-5131 or AP-5181 specifically.

However, there are several differences between the two models you should be aware of. The AP-5181 is constructed to support outdoor installations, while the AP-5131 model is constructed primarily for indoor deployments. The AP-5131 is available in numerous single and dual-radio SKUs, while an AP-5181 is available in only a dual-radio SKU. An AP-5181 cannot use the AP-5131???s 48 volt power supply (Part No. 50-14000-243R) and, therefore, is recommended to use the AP-5181 Power Tap (Part No. AP-PSBIAS-5181-01R) designed specifically for outdoor deployments. An AP-5181 model access point also must use an RJ-45 to Serial cable to establish a serial connection to a host computer. Additionally, an AP-5181 model access point cannot downgrade to 1.1.0.x (or earlier) firmware.

1-2 AP-51xx Access Point Product Reference Guide

The access point (AP) provides a bridge between Ethernet wired LANs or WANs and wireless networks. It provides connectivity between Ethernet wired networks and radio-equipped mobile units (MUs). MUs include the full line of terminals, adapters (PC cards, Compact Flash cards and PCI adapters) and other devices.

The access point provides a maximum 54Mbps data transfer rate via each radio. It monitors Ethernet traffic and forwards appropriate Ethernet messages to MUs over the network. It also monitors MU radio traffic and forwards MU packets to the Ethernet LAN.

If you are new to using an access point for managing your network, refer to Theory of Operations on page 1-20 for an overview on wireless networking fundamentals.

1.1 New Features

With this most recent 2.0 release of the access point firmware, the following new features have been introduced:

???Adaptive AP

???Rogue AP Enhancements

Legacy users can upgrade their firmware image to version 2.0. to benefit from the new features described in this section. For information on upgrading the access point???s firmware image, see

Updating Device Firmware on page 4-49.

1.1.1 Adaptive AP

An adaptive AP (AAP) is an AP-51XX access point that can adopt like an AP300 (L3). The management of an AAP is conducted by a switch, once the access point connects to a Motorola WS5100 or RFS7000 model switch and receives its AAP configuration.

An AAP provides:

1.2.1 Single or Dual Mode Radio Options

One or two possible configurations are available on the access point depending on which model is purchased. If the access point is manufactured as a single radio access point, the access point enables you to configure the single radio for either 802.11a or 802.11b/g. However, an AP-5181 model access point is only available in a dual-radio model.

If the access point is manufactured as a dual-radio access point, the access point enables you to configure one radio for 802.11a support, and the other for 802.11b/g support.

For detailed information, see Setting the WLAN???s Radio Configuration on page 5-51.

1.2.2 Separate LAN and WAN Ports

The access point has one LAN port and one WAN port, each with their own MAC address. The access point must manage all data traffic over the LAN connection carefully as either a DHCP client, BOOTP client, DHCP server or using a static IP address. The access point can only use a Power-over-Ethernet device when connected to the LAN port.

For detailed information on configuring the LAN port, see Configuring the LAN Interface on page 5-1.

A Wide Area Network (WAN) is a widely dispersed telecommunications network. In a corporate environment, the WAN port might connect to a larger corporate network. For a small business, the WAN port might connect to a DSL or cable modem to access the Internet. Regardless, network address information must be configured for the ???s intended mode of operation.

For detailed information on configuring the ???s WAN port, see Configuring WAN Settings on page 5-16.

The LAN and WAN port MAC addresses can be located within the LAN and WAN Stats screens.

Introduction 1-7

If the radio MAC address displayed on the Radio Settings screen is 00:A0:F8:72:20:DC, then the BSSIDs for that radio will have the following MAC addresses:

For detailed information on strategically mapping BSSIDs to WLANs, see Configuring the 802.11a or 802.11b/g Radio on page 5-55. For information on access point MAC address assignments, see

AP-51xx MAC Address Assignment on page 1-27.

1.2.7 Quality of Service (QoS) Support

The QoS implementation provides applications running on different wireless devices a variety of priority levels to transmit data to and from the access point. Equal data transmission priority is fine for data traffic from applications such as Web browsers, file transfers or email, but is inadequate for multimedia applications.

Voice over Internet Protocol (VoIP), video streaming and interactive gaming are highly sensitive to latency increases and throughput reductions. These forms of higher priority data traffic can significantly benefit from the QoS implementation.The WiFi Multimedia QOS Extensions (WMM) implementation used by the shortens the time between transmitting higher priority data traffic and is thus desirable for multimedia applications. In addition, U-APSD (WMM Power Save) is also supported.

WMM defines four access categories???voice, video, best effort and background???to prioritize traffic for enhanced multimedia support.

For detailed information on configuring QoS support, see Setting the WLAN Quality of Service (QoS) Policy on page 5-39.

1.2.8 Industry Leading Data Security

The access point supports numerous encryption and authentication techniques to protect the data transmitting on the WLAN.

The following authentication techniques are supported:

1-8 AP-51xx Access Point Product Reference Guide

???Kerberos Authentication

???EAP Authentication

The following encryption techniques are supported:

???WEP Encryption

???KeyGuard Encryption

???Wi-Fi Protected Access (WPA) Using TKIP Encryption

???WPA2-CCMP (802.11i) Encryption

In addition, the access point supports the following additional security features:

???Firewall Security

???VPN Tunnels

???Content Filtering

For an overview on the encryption and authentication schemes available , refer to Configuring Access Point Security on page 6-1.

1.2.8.1 Kerberos Authentication

Authentication is a means of verifying information transmitted from a secure source. If information is authentic, you know who created it and you know it has not been altered in any way since originated. Authentication entails a network administrator employing a software ???supplicant??? on their computer or wireless device.

Authentication is critical for the security of any wireless LAN device. Traditional authentication methods are not suitable for use in wireless networks where an unauthorized user can monitor network traffic and intercept passwords. The use of strong authentication methods that do not disclose passwords is necessary. The access point uses the Kerberos authentication service protocol (specified in RFC 1510) to authenticate users/clients in a wireless network environment and to securely distribute the encryption keys used for both encrypting and decrypting.

A basic understanding of RFC 1510 Kerberos Network Authentication Service (V5) is helpful in understanding how Kerberos functions. By default, WLAN devices operate in an open system network where any wireless device can associate with an AP without authorization. Kerberos requires device authentication before access to the wired network is permitted.

For detailed information on Kerbeors configurations, see Configuring Kerberos Authentication on page 6-8.

Introduction 1-9

1.2.8.2 EAP Authentication

The Extensible Authentication Protocol (EAP) feature provides access points and their associated MU???s an additional measure of security for data transmitted over the wireless network. Using EAP, authentication between devices is achieved through the exchange and verification of certificates.

EAP is a mutual authentication method whereby both the MU and AP are required to prove their identities. Like Kerberos, the user loses device authentication if the server cannot provide proof of device identification.

Using EAP, a user requests connection to a WLAN through the access point. The access point then requests the identity of the user and transmits that identity to an authentication server. The server prompts the AP for proof of identity (supplied to the by the user) and then transmits the user data back to the server to complete the authentication process.

An MU is not able to access the network if not authenticated. When configured for EAP support, the access point displays the MU as an EAP station.

EAP is only supported on mobile devices running Windows XP, Windows 2000 (using Service Pack #4) and Windows Mobile 2003. Refer to the system administrator for information on configuring a Radius Server for EAP (802.1x) support.

For detailed information on EAP configurations, see Configuring 802.1x EAP Authentication on page 6-11.

1.2.8.3 WEP Encryption

All WLAN devices face possible information theft. Theft occurs when an unauthorized user eavesdrops to obtain information illegally. The absence of a physical connection makes wireless links particularly vulnerable to this form of theft. Most forms of WLAN security rely on encryption to various extents. Encryption entails scrambling and coding information, typically with mathematical formulas called algorithms, before the information is transmitted. An algorithm is a set of instructions or formula for scrambling the data. A key is the specific code used by the algorithm to encrypt or decrypt the data. Decryption is the decoding and unscrambling of received encrypted data.

The same device, host computer or front-end processor, usually performs both encryption and decryption. The transmit or receive direction determines whether the encryption or decryption function is performed. The device takes plain text, encrypts or scrambles the text typically by mathematically combining the key with the plain text as instructed by the algorithm, then transmits the data over the network. At the receiving end, another device takes the encrypted text and decrypts, or unscrambles, the text revealing the original message. An unauthorized user can know the

1-10 AP-51xx Access Point Product Reference Guide

algorithm, but cannot interpret the encrypted data without the appropriate key. Only the sender and receiver of the transmitted data know the key.

Wired Equivalent Privacy (WEP) is an encryption security protocol specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11b and supported by the AP. WEP encryption is designed to provide a WLAN with a level of security and privacy comparable to that of a wired LAN. The level of protection provided by WEP encryption is determined by the encryption key length and algorithm. An encryption key is a string of case sensitive characters used to encrypt and decrypt data packets transmitted between a mobile unit (MU) and the access point. An access point and its associated wireless clients must use the same encryption key (typically 1 through 4) to interoperate.

For detailed information on WEP, see Configuring WEP Encryption on page 6-16.

1.2.8.4 KeyGuard Encryption

Use KeyGuard to shield the master encryption keys from being discovered through hacking. KeyGuard negotiation takes place between the access point and MU upon association. The access point can use KeyGuard with Motorola MUs. KeyGuard is only supported on Motorola MUs making it a Motorola proprietary security mechanism.

For detailed information on KeyGuard configurations, see Configuring KeyGuard Encryption on page 6-18.

1.2.8.5 Wi-Fi Protected Access (WPA) Using TKIP Encryption

Wi-Fi Protected Access (WPA) is a security standard for systems operating with a Wi-Fi wireless connection. WEP???s lack of user authentication mechanisms is addressed by WPA. Compared to WEP, WPA provides superior data encryption and user authentication.

WPA addresses the weaknesses of WEP by including:

???a per-packet key mixing function

???a message integrity check

???an extended initialization vector with sequencing rules

???a re-keying mechanism

WPA uses an encryption method called Temporal Key Integrity Protocol (TKIP). WPA employs 802.1X and Extensible Authentication Protocol (EAP).

For detailed information on WPA using TKIP configurations, see Configuring WPA/WPA2 Using TKIP on page 6-21.

Introduction 1-13

the latest firmware version for full feature functionality. An AP-5181 model access point does not support firmware earlier than 1.1.1.0.

For detailed information on updating the firmware using FTP or TFTP, see Updating Device Firmware on page 4-49.

1.2.12 Programmable SNMP v1/v2/v3 Trap Support

Simple Network Management Protocol (SNMP) facilitates the exchange of management information between network devices. SNMP uses Management Information Bases (MIBs) to manage the device configuration and monitor Internet devices in remote locations. MIB information accessed via SNMP is defined by a set of managed objects called object identifiers (OIDs). An object identifier (OID) is used to uniquely identify each object variable of a MIB.

SNMP allows a network administrator to configure the access point, manage network performance, find and solve network problems, and plan for network growth. The access point supports SNMP management functions for gathering information from its network components. The access point???s download site contains the following 2 MIB files:

???Symbol-CC-WS2000-MIB-2.0 (standard MIB file)

???Symbol-AP-5131-MIB (both the AP-5131 and AP-5181 use the same MIB, there is no specific MIB for an AP-5181)

The access point???s SNMP agent functions as a command responder and is a multilingual agent responding to SNMPv1, v2c and v3 managers (command generators). The factory default configuration maintains SNMPv1/2c support of community names, thus providing backward compatibility.

For detailed information on configuring SNMP traps, see Configuring SNMP Settings on page 4-23.

1.2.13 Power-over-Ethernet Support

When users purchase a Motorola WLAN solution, they often need to place access points in obscure locations. In the past, a dedicated power source was required for each access point in addition to the Ethernet infrastructure. This often required an electrical contractor to install power drops at each access point location.

An approved power injector solution merges power and Ethernet into one cable, reducing the burden of installation and allows optimal access point placement in respect to the intended radio coverage area. An AP-5131 or AP-5181 can only use a Power-over-Ethernet device when connected to the LAN port.

1-14 AP-51xx Access Point Product Reference Guide

The Power Injector (Part No. AP-PSBIAS-T-1P-AF) is a single-port, 802.3af compliant Power over Ethernet hub combining low-voltage DC with Ethernet data in a single cable connecting to the access point. The Power Injector???s single DC and Ethernet data cable creates a modified Ethernet cabling environment on the access point???s LAN port eliminating the need for separate Ethernet and power cables. For detailed information on using the Power Injector, see Power Injector and Power Tap Systems on page 2-10.

The Power Tap (Part No. AP-PSBIAS-5181-01R) is also a single-port, 802.3af compliant Power over Ethernet hub combining low-voltage DC with Ethernet data in a single cable connecting to the access point. However, the Power Tap is designed and ruggedized for use with an AP-5181???s outdoor deployment. For detailed information on using the Power Tap, see Power Injector and Power Tap Systems on page 2-10.

1.2.14 MU-MU Transmission Disallow

The access point???s MU-MU Disallow feature prohibits MUs from communicating with each other even if they are on different WLANs, assuming one of the WLAN???s is configured to disallow MU-MU communication. Therefore, if an MU???s WLAN is configured for MU-MU disallow, it will not be able to communicate with any other MUs connected to this access point.

For detailed information on configuring an WLAN to disallow MU to MU communications, see

Creating/Editing Individual WLANs on page 5-30.

1.2.15 Voice Prioritization

Each access point WLAN has the capability of having its QoS policy configured to prioritize the network traffic requirements for associated MUs. A WLAN QoS page is available for each enabled WLAN on either the 802.11a or 802.11b/g radio.

Use the QoS page to enable voice prioritization for devices to receive the transmission priority they may not normally receive over other data traffic. Voice prioritization allows the access point to assign priority to voice traffic over data traffic, and (if necessary) assign legacy voice supported devices (non WMM supported voice devices) additional priority.

For detailed information on configuring voice prioritization over other voice enabled devices, see

Setting the WLAN Quality of Service (QoS) Policy on page 5-39.

Introduction 1-15

1.2.16 Support for CAM and PSP MUs

The access point supports both CAM and PSP powered MUs. CAM (Continuously Aware Mode) MUs leave their radios on continuously to hear every beacon and message transmitted. These systems operate without any adjustments by the access point.

A beacon is a uniframe system packet broadcast by the AP to keep the network synchronized. A beacon includes the ESSID, MAC address, Broadcast destination addresses, a time stamp, a DTIM (Delivery Traffic Indication Message) and the TIM (Traffic Indication Map).

PSP (Power Save Polling) MUs power off their radios for short periods. When a MU in PSP mode associates with an access point, it notifies the access point of its activity status. The access point responds by buffering packets received for the MU. PSP mode is used to extend an MU???s battery life by enabling the MU to ???sleep??? during periods of inactivity.

1.2.17 Statistical Displays

The access point can display robust transmit and receive statistics for the WAN and LAN ports. WLAN stats can be displayed collectively and individually for enabled WLANs. Transmit and receive statistics are available for the access point???s 802.11a and 802.11b/g radios. An advanced radio statistics page is also available to display retry histograms for specific data packet retry information.

Associated MU stats can be displayed collectively and individually for specific MUs. An echo (ping) test is also available to ping specific MUs to assess association strength. Finally, the access point can detect and display the properties of other APs detected within the access point???s radio coverage area. The type of AP detected can be displayed as well as the properties of individual APs.

For detailed information on available access point statistical displays and the values they represent, see Monitoring Statistics on page 7-1.

1.2.18 Transmit Power Control

The access point has a configurable power level for each radio. This enables the network administrator to define the antenna???s transmission power level in respect to the access point???s placement or network requirements as defined in the site survey.

For detailed information on setting the radio transmit power level, see Configuring the 802.11a or 802.11b/g Radio on page 5-55.

1-16 AP-51xx Access Point Product Reference Guide

1.2.19 Advanced Event Logging Capability

The access point provides the capability for periodically logging system events. Logging events is useful in assessing the throughput and performance of the access point or troubleshooting problems on the access point managed Local Area Network (LAN).

For detailed information on access point events, see Logging Configuration on page 4-42.

1.2.20 Configuration File Import/Export Functionality

Configuration settings for an access point can be downloaded from the current configuration of another access point. This affords the administrator the opportunity to save the current configuration before making significant changes or restoring the default configuration.

For detailed information on importing or exporting configuration files, see Importing/Exporting Configurations on page 4-44.

1.2.21 Default Configuration Restoration

The access point has the ability to restore its default configuration or a partial default configuration (with the exception of current WAN and SNMP settings). Restoring the default configuration is a good way to create new WLANs if the MUs the access point supports have been moved to different radio coverage areas.

For detailed information on restoring a default or partial default configuration, see Configuring System Settings on page 4-2.

1.2.22 DHCP Support

The access point can use Dynamic Host Configuration Protocol (DHCP) to obtain a leased IP address and configuration information from a remote server. DHCP is based on the BOOTP protocol and can coexist or interoperate with BOOTP. Configure the access point to send out a DHCP request searching for a DHCP/BOOTP server to acquire HTML, firmware or network configuration files when the access point boots. Because BOOTP and DHCP interoperate, whichever responds first becomes the server that allocates information.

The access point can be set to only accept replies from DHCP or BOOTP servers or both (this is the default setting). Disabling DHCP disables BOOTP and DHCP and requires network settings to be set manually. If running both DHCP and BOOTP, do not select BOOTP Only. BOOTP should only be used when the server is running BOOTP exclusively.

Introduction 1-17

The DHCP client automatically sends a DHCP request at an interval specified by the DHCP server to renew the IP address lease as long as the access point is running (this parameter is programmed at the DHCP server). For example: Windows 2000 servers typically are set for 3 days.

1.2.23 Multi-Function LEDs

Both AP-5131 and AP-5181 model access points house seven LED indicators. Four LEDs exist on the top of the and are visible from wall, ceiling and table-top orientations. Three of these four LEDs are single color activity LEDs, and one is a multi-function red and white status LED. Two LEDs exist on the rear of the access point and are viewable using a single (customer installed) extended light pipe, adjusted as required to suit above the ceiling installations.

For detailed information on the access point LEDs and their functionality, see AP-5131 LED Indicators on page 2-23 or AP-5181 LED Indicators on page 2-29.

1.2.24 Mesh Networking

Utilize the new mesh networking functionality to allow the access point to function as a bridge to connect two Ethernet networks or as a repeater to extend your network???s coverage area without additional cabling. Mesh networking is configurable in two modes. It can be set in a wireless client bridge mode and/or a wireless base bridge mode (which accepts connections from client bridges). These two modes are not mutually exclusive.

In client bridge mode, the access point scans to find other access points using the selected WLAN???s ESSID. The access point must go through the association and authentication process to establish a wireless connection. The mesh networking association process is identical to the access point???s MU association process. Once the association/authentication process is complete, the wireless client adds the connection as a port on its bridge module. This causes the access point (in client bridge mode) to begin forwarding configuration packets to the base bridge. An access point in base bridge mode allows the access point radio to accept client bridge connections.

The two bridges communicate using the Spanning Tree Protocol (STP). The spanning tree determines the path to the root and detects if the current connection is part of a network loop with another connection. Once the spanning tree converges, both access points begin learning which destinations reside on which side of the network. This allows them to forward traffic intelligently.

After the access point (in client bridge mode) establishes at least one wireless connection, it will begin beaconing and accepting wireless connections (if configured to support mobile users). If the access point is configured as both a client bridge and a base bridge, it begins accepting client bridge connections. In this way, the mesh network builds itself over time and distance.

1-18 AP-51xx Access Point Product Reference Guide

Once the access point (in client bridge mode) establishes at least one wireless connection, it establishes other wireless connections in the background as they become available. In this way, the access point can establish simultaneous redundant links. An access point (in client bridge mode) can establish up to 3 simultaneous wireless connections with other AP-5131s or AP-5181s. A client bridge always initiates the connections and the base bridge is always the acceptor of the mesh network data proliferating the network.

Since each access point can establish up to 3 simultaneous wireless connections, some of these connections may be redundant. In that case, the STP algorithm determines which links are the redundant links and disables the links from forwarding.

For an overview on mesh networking as well as details on configuring the access point???s mesh networking functionality, see Configuring Mesh Networking on page 9-1.

1.2.25 Additional LAN Subnet

In a typical retail or small office environment (wherein a wireless network is available along with a production WLAN) it is frequently necessary to segment a LAN into two subnets. Consequently, a second LAN is necessary to ???segregate??? wireless traffic.

The access point now has a second LAN subnet enabling administrators to segment the access point???s LAN connection into two separate networks. The main access point LAN screen now allows the user to select either LAN1 or LAN2 as the active LAN over the access point???s Ethernet port. Both LANs can still be active at any given time, but only one can transmit over the access point???s physical LAN connection. Each LAN has a separate configuration screen (called LAN 1 and LAN 2 by default) accessible under the main LAN screen. The user can rename each LAN as necessary. Additionally, each LAN can have its own Ethernet Type Filter configuration, and subnet access (HTTP, SSH, SNMP and telnet) configuration.

For detailed information on configuring the access point for additional LAN subnet support, see

Configuring the LAN Interface on page 5-1.

1.2.26 On-board Radius Server Authentication

The access point has the ability to work as a Radius Server to provide user database information and user authentication. Several new screens have been added to the access point???s menu tree to configure Radius server authentication and configure the local user database and access policies. A new Radius Server screen allows an administrator to define the data source, authentication type and associate digital certificates with the authentication scheme. The LDAP screen allows the administrator to configure an external LDAP Server for use with the access point. A new Access Policy

Introduction 1-19

screen enables the administrator to set WLAN access based on user groups defined within the User Database screen. Each user is authorized based on the access policies applicable to that user. Access policies allow an administrator to control access to a user groups based on the WLAN configurations.

For detailed information on configuring the access point for AAA Radius Server support, see

Configuring User Authentication on page 6-64.

1.2.27 Hotspot Support

The access point allows hotspot operators to provide user authentication and accounting without a special client application. The access point uses a traditional Internet browser as a secure authentication device. Rather than rely on built-in 802.11security features to control access point association privileges, you can configure a WLAN with no WEP (an open network). The access point issues an IP address to the user using a DHCP server, authenticates the user and grants the user to access the Internet.

If a tourist visits a public hotspot and wants to browse a Web page, they boot their laptop and associate with a local Wi-Fi network by entering a valid SSID. They start a browser, and the hotspot???s access controller forces the un-authenticated user to a Welcome page (from the hotspot operator) that allows the user to login with a username and password. In order to send a redirected page (a login page), a TCP termination exists locally on the access point. Once the login page displays, the user enters their credentials. The access point connects to the Radius server and determines the identity of the connected wireless user. Thus, allowing the user to access the Internet once successfully authenticated.

For detailed information on configuring the access point for Hotspot support, see Configuring WLAN Hotspot Support on page 5-45.

1.2.28 Routing Information Protocol (RIP)

RIP is an interior gateway protocol that specifies how routers exchange routing-table information. The parent Router screen also allows the administrator to select the type of RIP and the type of RIP authentication used.

For detailed information on configuring RIP functionality as part of the access point???s Router functionality, see Setting the RIP Configuration on page 5-67.

1-20 AP-51xx Access Point Product Reference Guide

1.2.29 Manual Date and Time Settings

As an alternative to defining a NTP server to provide access point system time, the access point can now have its date and time set manually. A new Manual Date/Time Setting screen can be used to set the time using a Year-Month-Day HH:MM:SS format.

For detailed information on manually setting the access point???s system time, see Configuring Network Time Protocol (NTP) on page 4-39.

1.2.30 Dynamic DNS

The access point supports the Dynamic DNS service. Dynamic DNS (or DynDNS) is a feature offered by www.dyndns.com which allows the mapping of domain names to dynamically assigned IP addresses. When the dynamically assigned IP address of a client changes, the new IP address is sent to the DynDNS service and traffic for the specified domain(s) is routed to the new IP address. For information on configuring the Dynamic DNS feature, see Configuring Dynamic DNS on page 5-25.

1.2.31 Auto Negotiation

Auto negotiation enables the access point to automatically exchange information (over either its LAN or WAN port) about data transmission speed and duplex capabilities. Auto negotiation is helpful when using the access point in an environment where different devices are connected and disconnected on a regular basis. For information on configuring the auto negotiation feature, see

Configuring the LAN Interface on page 5-1 or Configuring WAN Settings on page 5-16

1.3 Theory of Operations

To understand access point management and performance alternatives, users need familiarity with functionality and configuration options. The access point includes features for different interface connections and network management.

The access point uses electromagnetic waves to transmit and receive electric signals without wires. Users communicate with the network by establishing radio links between mobile units (MUs) and access points.

The access point uses DSSS (direct sequence spread spectrum) to transmit digital data from one device to another. A radio signal begins with a carrier signal that provides the base or center frequency. The digital data signal is encoded onto the carriers using a DSSS chipping algorithm. The radio signal propagates into the air as electromagnetic waves. A receiving antenna (on the MU) in the path of the waves absorbs the waves as electrical signals. The receiving MU interprets

Introduction 1-21

(demodulates) the signal by reapplying the direct sequence chipping code. This demodulation results in the original digital data.

The access point uses its environment (the air and certain objects) as the transmission medium.The access point can either transmit in the 2.4 to 2.5-GHz frequency range (802.11b/g radio) or the 5.2 GHz frequency range (802.11a radio), the actual range is country-dependent. Motorola devices, like other Ethernet devices, have unique, hardware encoded Media Access Control (MAC) or IEEE addresses. MAC addresses determine the device sending or receiving data. A MAC address is a 48- bit number written as six hexadecimal bytes separated by colons. For example: 00:A0:F8:24:9A:C8

1.3.1 Cellular Coverage

An access point establishes an average communication range with MUs called a Basic Service Set (BSS) or cell. When in a particular cell, the MU associates and communicates with the access point supporting the radio coverage area of that cell. Adding ???s to a single LAN establishes more cells to extend the range of the network. Configuring the same ESSID (Extended Service Set Identifier) on all access points makes them part of the same Wireless LAN.

Access points with the same ESSID define a coverage area. A valid ESSID is an alphanumeric, case- sensitive identifier up to 32 characters. An MU searches for an access point with a matching ESSID and synchronizes (associates) to establish communications. This device association allows MUs within the coverage area to move about or roam. As the MU roams from cell to cell, it associates with a different access point. The roam occurs when the MU analyzes the reception quality at a location and determines a different provides better signal strength and lower MU load distribution.

Introduction 1-25

???Access Point - As an Access Point, the access point functions as a layer 2 bridge. The wired uplink can operate as a trunk and support multiple VLANs. Up to 16 WLANs can be defined and mapped to WLANs. Each WLAN can be configured to be broadcast by one or both radios (unlike the AP-4131 model access point). An AP-5131 or AP-5181 can operate in both an Access Point mode and Wireless Gateway/Router mode simultaneously. The network architecture and access point configuration define how the Access Point and Wireless Gateway/Router mode are negotiated.

???Wireless Gateway/Router - If operating as a Wireless Gateway/Router, the access point functions as a router between two layer 2 networks: the WAN uplink (the ethernet port) and the Wireless side. The following options are available providing a solution for single-cell deployment:

???PPPoE - The WAN interface can terminate a PPPoE connection, thus enabling the access point to operate in conjunction with a DSL or Cable modem to provide WAN connectivity.

???NAT - (Network Address Translation) on the Wireless interface. Using NAT, the router is able to manage a private IP scheme. NAT allows translation of private addresses to the WAN IP address.

???DHCP - On the Wireless side, the can assign private IP addresses.

???Firewall - In between the WAN and Wireless interfaces, a Firewall protects against a number of known attacks.

1.3.7 Management Access Options

Managing the access point includes viewing network statistics and setting configuration options. Statistics track the network activity of associated MUs and data transfers on the AP interfaces.

The access point requires one of the following connection methods to perform a custom installation and manage the network:

???Secure Java-Based WEB UI - (use Sun Microsystems??? JRE 1.5 or higher available from Sun???s Web site and be sure to disable Microsoft???s Java Virtual Machine if installed)

???Command Line Interface (CLI) via Serial, Telnet and SSH

???Config file - Human-readable; Importable/Exportable via FTP and TFTP

???MIB (Management Information Base) accessing the access point SNMP function using a MIB Browser. The AP-5131 or AP-5181 downloads site contains the following 2 MIB files:

???Symbol-CC-WS2000-MIB-2.0 (standard MIB file)

???Symbol-AP-5131-MIB (AP-5131/AP-5181 MIB file)

1-26 AP-51xx Access Point Product Reference Guide

Make configuration changes to access point???s individually. Optionally, use the access point import/export configuration function to download settings to other access points.

For detailed information, see Importing/Exporting Configurations on page 4-44.

Introduction 1-27

1.3.8 AP-51xx MAC Address Assignment

For both an AP-5131 and AP-5181 model access point, MAC address assignments are as follows:

???WAN - The access point MAC address can be found underneath the access point chassis.

???LAN1 - WAN MAC address + 1.

???LAN2 - A virtual LAN not mapped to the LAN Ethernet port. This address is the lowest of the two radio MAC addresses.

???Radio1 (802.11bg) - Random address located on the Web UI, CLI and SNMP interfaces.

???Radio2 (802.11a) - Random address located on the Web UI, CLI and SNMP interfaces.

The access point???s BSS (virtual AP) MAC addresses are calculated as follows:

???BSS1 - The same as the corresponding base radio???s MAC address.

???BSS2 - Base radio MAC address +1

???BSS3 - Base radio MAC address +2

???BSS4 - Base radio MAC address +3

The Power Injector (Part No. AP-PSBIAS-1P2-AFR) is included in certain orderable configurations, but can be added to any configuration. For more information on the Power Injector, see Power Injector and Power Tap Systems on page 2-10.

2-4 AP-51xx Access Point Product Reference Guide

NOTE A standard 48 Volt Power Adapter (Part No. 50-14000-243R) is recommended with AP-5131 product SKUs that do not include the Power Injector.

For an overview on the optional antennae for the AP-5131, see Antenna Options on page 2-6. For detailed specifications on the 2.4 GHz and 5.2 GHz antenna suite, see 2.4 GHz Antenna Matrix on

page A-5 and 5.2 GHz Antenna Matrix on page A-6.

CAUTION Using an antenna other than the Dual-Band Antenna (Part No.

! ML-2452-APA2-01) could render the AP-5131???s Rogue AP Detector Mode feature inoperable. Contact your sales associate for specific information.

2.2.2 AP-5181 Configurations

Unlike the AP-5131, an AP-5181 is only available in a dual-radio configuration. There is one mechanical version of the AP-5181 providing one SKU option (with both 802.11a and 802.11g radios in the access point). The following is the AP-5181 orderable SKU:

1 WEEE Regulatory Addendum

1 set of cable connectors

3 antenna dust cover

2 connector cover AP67 jack, plus chain_LTW-M9/14-SB

NOTE To mount the AP-5181 access point to a pole (1.5 - 18 inches in diameter) an AP-5181 Mounting Kit (Part No. KT-5181-WP-01R) can be separately ordered. This kit contains the brackets and accessories required to mount the AP-5181 to a pole or wall.

NOTE If installing the AP-5181 in an outdoor area prone to high winds and rain, Motorola recommends using the AP-5181 Heavy Weather Kit (Part No. KT-5181-HW-01R). This kit shields an AP-5181 from wind and rain damage resulting from driving rain.

Hardware Installation 2-5

NOTE Though the AP-5181 can use the standard Power Injector solution (Part No. AP-PSBIAS-1P2-AFR), Motorola recommends using the AP-5181 Power Tap (Part No. AP-PSBIAS-5181-01R), designed specifically for outdoor deployments.

2.3 Requirements

The minimum installation requirements for a single-cell, peer-to-peer network (regardless of access point model)

???An AP-5131 (either a dual or single radio model) or AP-5181 model access point

???48 Volt Power Supply Part No. 50-14000-243R (AP-5131 models only) or Power Injector (Part No. AP-PSBIAS-1P2-AFR or AP-PSBIAS-5181-01R)

???A power outlet

???Dual-Band Antennae.

NOTE An AP-5131 or AP-5181 model access point optimally uses 2 antennae for the single-radio model and 4 antenna for the dual-radio model. The AP-5181 uses an antenna suite designed primarily for outdoor usage. For more information, see Antenna Specifications on page A-5.

2.4 Access Point Placement

For optimal performance, install the access point (regardless of model) away from transformers, heavy-duty motors, fluorescent lights, microwave ovens, refrigerators and other industrial equipment. Signal loss can occur when metal, concrete, walls or floors block transmission. Install the access point in open areas or add access points as needed to improve coverage.

Antenna coverage is analogous to lighting. Users might find an area lit from far away to be not bright enough. An area lit sharply might minimize coverage and create dark areas. Uniform antenna placement in an area (like even placement of a light bulb) provides even, efficient coverage.

Place the access point using the following guidelines:

???Install the access point at an ideal height of 10 feet from the ground.

???Orient the access point antennae vertically for best reception.

???Point the access point antenna(s) downward if attaching to the ceiling.

2-6 AP-51xx Access Point Product Reference Guide

To maximize the access point???s radio coverage area, Motorola recommends conducting a site survey to define and document radio interference obstacles before installing the access point.

2.4.1 Site Surveys

A site survey analyzes the installation environment and provides users with recommendations for equipment and placement. The optimum placement of 802.11a access points differs from 802.11b/g access points, because the locations and number of access points required are different to support the radio coverage area.

Motorola recommends conducting a new site survey and developing a new coverage area floor plan when switching from 2 or 11Mbps access points (AP-3021 or AP-4131 models) to 54Mbps access points (AP-5131 and AP-5181 models), as the device placement requirements are significantly different.

2.4.2 Antenna Options

2.4.2.1 AP-5131 Antenna Options

Both Radio 1 and Radio 2 require one antenna and can optimally use two antennae per radio (4 antennae total for dual-radio models). Two antennae per radio provides diversity that can improve performance and signal reception. Motorola supports two antenna suites for the AP-5131. One antenna suite supporting the 2.4 GHz band and another antenna suite supporting the 5.2 GHz band. Select an antenna model best suited to the intended operational environment of your AP-5131.

NOTE On a single-radio AP-5131, Radio 1 can be configured to be either a 2.4 GHz or 5.2 GHz radio. On a dual-radio model, Radio 1 refers to the AP- 5131???s 2.4 GHz radio and Radio 2 refers to the AP-5131 5.2 GHz radio. However, there could be some cases where a dual-radio AP-5131 is performing a Rogue AP detector function. In this scenario, the AP-5131 is receiving in either 2.4 GHz or 5.2 GHz over the Radio 1 or Radio 2 antennae depending on which radio is selected for the scan.

Antenna connectors for Radio 1 are located in a different location from the Radio 2 antenna connectors. On single radio versions, the R-SMA connectors can support both bands and should be connected to a R-SMA dual-band antenna or an appropriate single band antenna. If necessary a R-SMA to R-BNC adapter (Part No. 25-72178-01) can be purchased separately.

Hardware Installation 2-7

The AP-5131 2.4 GHz antenna suite includes the following models:

NOTE An additional adapter is required to use ML-2499-11PNA2-01 and ML-2499-BYGA2-01 model antennae. Please contact Motorola for more information.

2.5 Power Options

2.5.1 AP-5131 Power Options

The power options for the AP-5131 include:

???Power Injector (Part No. AP-PSBIAS-1P2-AFR)

???48-Volt Power Supply (Part No. 50-14000-243R)

???Any standard 802.3af compliant device.

2-10 AP-51xx Access Point Product Reference Guide

2.5.2 AP-5181 Power Options

The power options for the AP-5181 include:

CAUTION An AP-5181 model access point cannot use the AP-5131

! recommended 48-Volt Power Supply (Part No. 50-14000-243R). Motorola recommends the AP-PSBIAS-5181-01R Power Tap for use an AP-5181 and its intended outdoor deployment.

???Power Injector (Part No. AP-PSBIAS-1P2-AFR)

???Power Tap (Part No. AP-PSBIAS-5181-01R)

???Any standard 802.3af compliant device.

2.6Power Injector and Power Tap Systems

An AP-5131 or AP-5181 access point can receive power via an Ethernet cable connected to the access point???s LAN port (using the 802.3af standard). When users purchase a WLAN solution, they often need to place access points in obscure locations. In the past, a dedicated power source was required for each access point in addition to the Ethernet infrastructure. This often required an electrical contractor to install power drops at each access point location.

The Power Injector and Power Tap solutions merge power and Ethernet into one cable, reducing the burden of installation and allow optimal access point placement in respect to the intended radio coverage area.

Both the Power Injector and Power Tap are integrated AC-DC converters requiring 110-220 VAC power to combine low-voltage DC with Ethernet data in a single cable connecting to the access point. The access point can only use a Power Injector or Power Tap when connecting the unit to the access point???s LAN port. The Power Injector (Part No. AP-PSBIAS-1P2-AFR) is included in certain AP-5131 kits. The AP-5181 Power Tap (Part No. AP-PSBIAS-5181-01R) is ordered separately and is intended for AP-5181 outdoor deployments.

NOTE Though an AP-5181 can use the standard Power Injector solution (Part No. AP-PSBIAS-1P2-AFR), Motorola recommends using the AP-5181 Power Tap (Part No. AP-PSBIAS-5181-01R) designed especially for outdoor deployments.

Hardware Installation 2-11

CAUTION The access point supports any standards-based 802.3af compliant ! power source (including non-Motorola power sources). However,

using the wrong solution (including a POE system used on a legacy Motorola access point) could severely damage the access point and void the product warranty.

A separate Power Injector or Power Tap is required for each access point comprising the network.

2.6.1 Installing the Power Injector or Power Tap

Configure the access point as a DHCP client. For optimal screen resolution, set your screen resolution to 1024 x 768 pixels or greater.

1.Log in using admin as the default Username and motorola as the default Password. Use your new password if it has been updated from default.

There is no difference in the login method between the AP-5131 and AP-5181 model access points. However, each model displays a login screen unique in appearance (with a different model name). Additionally, each model access point displays a banner on top of each menu screen unique to the AP-5131 or AP-5181 model supported.

NOTE For optimum compatibility, use Sun Microsystems??? JRE 1.5 or higher (available from Sun???s Website), and be sure to disable Microsoft???s Java Virtual Machine if installed.

Getting Started 3-7

The export function will always export the encrypted Admin User password. The import function will import the Admin Password only if the access point is set to factory default. If the access point is not configured to factory default settings, the Admin User password WILL NOT get imported.

.

NOTE Though the access point can have its basic settings defined using a number of different screens, Motorola recommends using the access point Quick Setup screen to set the correct country of operation and define its minimum required configuration from one convenient location.

3.5.1 Configuring Device Settings

Configure a set of minimum required device settings within the Quick Setup screen. The values defined within the Quick Setup screen are also configurable in numerous other locations within the menu tree. When you change the settings in the Quick Setup screen, the values also change within the screen where these parameters also exist. Additionally, if the values are updated in these other screens, the values initially set within the Quick Setup screen will be updated.

To define a basic access point configuration:

1.Select System Configuration -> Quick Setup from the menu tree, if the Quick Setup screen is not already displayed.

2.Enter a System Name for the access point.

3-8 AP-51xx Access Point Product Reference Guide

The System Name is useful if multiple devices are being administered.

3.Select the Country for the access point???s country of operation from the drop-down menu

The access point prompts the user for the correct country code on the first login. A warning message also displays stating that an incorrect country settings may result in illegal radio operation. Selecting the correct country is central to legally operating the access point. Each country has its own regulatory restrictions concerning electromagnetic emissions and the maximum RF signal strength that can be transmitted. To ensure compliance with national and local laws, be sure to set the country accurately. CLI and MIB users cannot configure their access point until a two character country code (for example, United States - us) is set. Refer to Appendix A, Country Codes on page A-9 for the two character country codes.

NOTE The System Name and Country are also configurable within the System Settings screen. Refer to Configuring System Settings on page 4-2 (if necessary) to set a system location and admin email address for the access point or to view other default settings.

Getting Started 3-9

4.Optionally enter the IP address of the server used to provide system time to the access point within the Time Server field.

NOTE DNS names are not supported as a valid IP address. The user is required to enter a numerical IP address.

Once the IP address is entered, the access point???s Network Time Protocol (NTP) functionality is engaged automatically. Refer to the access point Product Reference Guide for information on defining alternate time servers and setting a synchronization interval for the access point to adjust its displayed time. Refer to Configuring Network Time Protocol (NTP) on page 4-39

(if necessary) for information on setting alternate time servers and setting a synchronization interval for the access point to adjust its displayed time.

5.Click the WAN tab to set a minimum set of parameters for using the WAN interface.

a.Select the Enable WAN Interface checkbox to enable a connection between the access point and a larger network or outside world through the WAN port. Disable this option to effectively isolate the access point???s WAN connection. No connections to a larger network or the Internet will be possible. MUs cannot communicate beyond the configured subnets.

b.Select the This Interface is a DHCP Client checkbox to enable DHCP for the access point???s WAN connection. This is useful, if the larger corporate network or Internet Service Provider (ISP) uses DHCP. DHCP is a protocol that includes mechanisms for IP address allocation and delivery of host-specific configuration parameters from a DHCP server to a host. Some of these parameters are IP address, network mask, and gateway.

NOTE Motorola recommends that the WAN and LAN ports should not both be configured as DHCP clients.

c.Specify an IP address for the access point???s WAN connection. An IP address uses a series of four numbers expressed in dot notation, for example, 190.188.12.1 (no DNS names supported).

d.Specify a Subnet Mask for the access point???s WAN connection. This number is available from the ISP for a DSL or cable-modem connection, or from an administrator if the access point connects to a larger network. A subnet mask uses a series of four numbers expressed in dot notation. For example, 255.255.255.0 is a valid subnet mask.

3-12 AP-51xx Access Point Product Reference Guide

a.Enter the Extended Services Set Identification (ESSID) and name associated with the WLAN. For additional information on creating and editing up to 16 WLANs per access point, see Creating/Editing Individual WLANs on page 5-30.

b.Use the Available On checkboxes to define whether the target WLAN is operating over the 802.11a or 802.11b/g radio. Ensure the radio selected has been enabled (see step 8).

c.Even an access point configured with minimal values must protect its data against theft and corruption. A security policy should be configured for WLAN1 as part of the basic configuration outlined in this guide. A security policy can be configured for the WLAN from within the Quick Setup screen. Policies can be defined over time and saved to be used as needed as security requirements change. Motorola recommends you familiarize yourself with the security options available on the access point before defining a security policy. Refer to Configuring WLAN Security Settings on page 3-12.

11.Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on the access point Quick Setup screen to the last saved configuration.

3.5.1.1 Configuring WLAN Security Settings

To configure a basic security policy for a WLAN:

1.From the access point Quick Setup screen, click the Create button to the right of the Security Policy item.

The New Security Policy screen displays with the Manually Pre-shared key/No authentication and No Encryption options selected. Naming and saving such a policy (as is) would provide no security and might only make sense in a guest network wherein no sensitive data is either transmitted or received. Consequently, at a minimum, a basic security scheme (in this case WEP 128) is recommended in a network environment wherein sensitive data is transmitted.

NOTE For information on configuring the other encryption and authentication options available to the access point, see Configuring Security Options on page 6-2.

2.Ensure the Name of the security policy entered suits the intended configuration or function of the policy.

Multiple WLANs can share the same security policy, so be careful not to name security policies after specific WLANs or risk defining a WLAN to single policy. Motorola

Getting Started 3-13

recommends naming the policy after the attributes of the authentication or encryption type selected.

3.Select the WEP 128 (104 bit key) checkbox.

The WEP 128 Settings field displays within the New Security Policy screen.

4.Configure the WEP 128 Settings field as required to define the Pass Key used to generate the WEP keys.

3-14 AP-51xx Access Point Product Reference Guide

5.Click the Apply button to save the security policy and return to the access point Quick Setup screen.

At this point, you can test the access point for MU interoperability.

3.5.2Testing Connectivity

Verify the access point???s link with an MU by sending Wireless Network Management Protocol (WNMP) ping packets to the associated MU. Use the Echo Test screen to specify a target MU and configure the parameters of the test. The WNMP ping test only works with Motorola MUs. Only use a Motorola MU to test access point connectivity using WNMP.

NOTE Before testing for connectivity, the target MU needs to be set to the same ESSID as the access point. Since WEP 128 has been configured for the access point, the MU also needs to be configured for WEP 128 and use the same WEP keys. Ensure the MU is associated with the access point before testing for connectivity.

To ping a specific MU to assess its connection with an access point:

1.Select Status and Statistics -> MU Stats from the menu tree.

2.Select the Echo Test button from within the MU Stats Summary screen.

3.Define the following parameters for the test.

Getting Started 3-15

4.Click the Ping button to begin transmitting packets to the specified MU address.

Refer to the Number of Responses value to assess the number of responses from the MU versus the number of ping packets transmitted by the access point. Use the ratio of packets sent versus the number of packets received the link quality between the MU and the access point.

Click the OK button to exit the Echo Test screen and return to the MU Stats Summary screen.

3.5.3Where to Go from Here?

Once basic connectivity has been verified, the access point can be fully configured to meet the needs of the network and the users it supports. Refer to the following:

4-6 AP-51xx Access Point Product Reference Guide

7.Click Logout to securely exit the access point Access Point applet. A prompt displays confirming the logout before the applet is closed.

4.2Adaptive AP Setup

An access point needs settings defined to discover (and adopt) an available switch and establish a connection and data tunnel. It???s through this switch adoption that the access point receives its adaptive AP (AAP) configuration. With the 2.0 access point firmware release, a new screen has been added to define the mechanisms used to adopt a switch and route AAP configuration information.

NOTE For an AAP overview and a theoretical discussion of how an access point discovers a switch to creates a secure data tunnel for adaptive AP operation, see Adaptive AP on page 10-1.

NOTE AAP functionality is only supported on a Motorola WS5100 model switch (running firmware version 3.1) or higher and a Motorola RFS7000 model switch (running firmware version 1.1 or higher).

NOTE The Adaptive AP Setup screen does not display the AAP???s adoption status or adopted switch. This information is available using the access point???s CLI. To review AAP adoption status and adopted switch information, see

AP51xx>admin(system.aap-setup)>show on page 8-149.

To configure the access point???s switch discovery method and connection medium:

1. Select System Configuration -> Adaptive AP Setup from the menu tree.

System Configuration 4-7

2.Define the following to prioritize a switch connection scheme and AP interface used to adopt to the switch.

4-8 AP-51xx Access Point Product Reference Guide

Auto Discovery Enable When the Auto Discovery Enable checkbox is selected, the access point begins the switch discovery (adoption) process using DHCP first, then a user provided domain name, lastly using static IP addresses. This setting is disabled by default. When disabled, the AP functions as a standalone access point without trying to adopt a switch. Consequently, the access point will not be able to obtain an AAP configuration. For an overview of AAP and instructions on how to setup the AP and switch, see Adaptive AP Overview.

3.Refer to the 12 available Switch IP Addresses to review the addresses the access point uses to adopt with a switch.

The access point contacts each switch on the list (from top to bottom) until a viable switch adoption is made. The access point first populates the list with the IP addresses received from its DHCP resource. If DHCP is not able to obtain IP addresses, the access point attempts to resolve the switch's Domain Name if provided within the Switch FQDN parameter. However, if the access point receives one or more IP addresses from the DHCP server, it will not solicit an IP address from a user provided domain name. Lastly, provide static (manually provided) IP addresses to the list as long as there is room. The access point will defer to these addresses if DHCP and a provided domain address fail to secure a switch adoption.

4.Click Apply to save any changes to the Adaptive AP Setup screen. Navigating away from the screen without clicking the Apply button results in all changes to the screen being lost.

5.Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on the Adaptive AP Setup screen to the last saved configuration.

6.Click Logout to securely exit the access point Access Point applet. A prompt displays confirming the logout before the applet is closed.

System Configuration 4-9

4.3 Configuring Data Access

Use the AP-51XX Access screen to allow/deny management access to the access point from different subnets (LAN1, LAN2 or WAN) using different protocols such as HTTP, HTTPS, Telnet, SSH or SNMP. The access options are either enabled or disabled. It is not meant to function as an ACL in routers or other firewalls, where you can specify and customize specific IPs to access specific interfaces.

Use the access point???s Access screen checkboxes to enable or disable LAN1, LAN2 and/or WAN access using the protocols and ports listed. If access is disabled, this effectively locks out the administrator from configuring the access point using that interface. To avoid jeopardizing the network data managed by the access point, Motorola recommends enabling only those interfaces used in the routine (daily) management of the network, and disabling all other interfaces until they are required.

The AP-51XX Access screen also has a new facility allowing customers to create a login message with customer generated text. When enabled (using either the access point Web UI or CLI), the login message displays when the user is logging into the access point. If the login message is disabled, the default login screen displays with no message.

To configure access for the access point:

1. Select System Configuration -> AP-51xx Access from the menu tree.

4-10 AP-51xx Access Point Product Reference Guide

2.Use the access point Access field checkboxes to enable/disable the following on the access point???s LAN1, LAN2 or WAN interfaces:

Applet HTTP (port 80) Select the LAN1, LAN2 and/or WAN checkboxes to enable access to the access point configuration applet using a Web browser.

Applet HTTPS (port Select the LAN1, LAN2 and/or WAN checkboxes to enable access 443)to the access point configuration applet using a Secure Sockets Layer (SSL) for encrypted HTTP sessions.

CLI TELNET (port 23) Select the LAN1, LAN2 and/or WAN checkboxes to enable access to the access point CLI via the TELNET terminal emulation TCP/IP protocol.

CLI SSH (port 22) Select the LAN1, LAN2 and/or WAN checkboxes to enable access to the access point CLI using the SSH (Secure Shell) protocol.

System Configuration 4-11

SNMP (port 161) Select the LAN1, LAN2 and/or WAN checkboxes to enable access to the access point configuration settings from an SNMP-capable client.

3. Refer to the Applet Timeout field to set an HTTPS timeout interval.

4.5Configuring SNMP Settings

Simple Network Management Protocol (SNMP) facilitates the exchange of management information between network devices. SNMP uses Management Information Bases (MIBs) to manage the device configuration and monitor Internet devices in potentially remote locations. MIB information accessed via SNMP is defined by a set of managed objects called object identifiers (OIDs). An object identifier (OID) is used to uniquely identify each object variable of a MIB. The AP-5131-MIB can be used with an AP-5181 model access point (there is no separate MIB for an AP-5181 model access point). The access point Web download package contains the following 2 MIB files:

???Symbol-CC-WS2000-MIB-2.0 (common MIB file)

???Symbol-AP-5131-MIB (AP-5131 specific MIB file)

NOTE The Symbol-AP-5131-MIB contains the majority of the information contained within the Symbol-CC-WS2000-MIB-2.0 file. This feature rich information has been validated with the Motorola WS2000 and proven reliable. The remaining portion of the Symbol-AP-5131-MIB contains supplemental information unique to the access point feature set.

4-24 AP-51xx Access Point Product Reference Guide

If using the Symbol-CC-WS2000-MIB-2.0 and/or Symbol-AP-5131-MIB to configure the AP-5131, use the table below to locate the MIB where the feature can be configured.

System Configuration 4-25

SNMP allows a network administrator to manage network performance, find and solve network problems, and plan for network growth. The access point supports SNMP management functions for gathering information from its network components, communicating that information to specified users and configuring the access point. All the fields available within the access point are also configurable within the MIB.

The access point SNMP agent functions as a command responder and is a multilingual agent responding to SNMPv1, v2c and v3 managers (command generators). The factory default configuration maintains SNMPv1/2c support of the community names, hence providing backward compatibility.

SNMP v1/v2c community definitions and SNMP v3 user definitions work independently, and both use the Access Control List (ACL) of the SNMP Access Control sub-screen.

Use the SNMP Access screen to define SNMP v1/v2c community definitions and SNMP v3 user definitions. SNMP version 1 (v1) provides a strong network management system, but its security is relatively weak. The improvements in SNMP version 2c (v2c) do not include the attempted security enhancements of other version-2 protocols. Instead, SNMP v2c defaults to SNMP-standard community strings for read-only and read/write access. SNMP version 3 (v3) further enhances protocol features, providing much improved security. SNMP v3 encrypts transmissions and provides authentication for users generating requests.

System Configuration 4-27

3.Configure the SNMP v3 User Definitions field (if SNMP v3 is used) to add and configure SNMP v3 user definitions.

SNMP v3 user definitions allow read-only or read/write access to management information as appropriate.

4-28 AP-51xx Access Point Product Reference Guide

4. Specify the users who can read and optionally modify the SNMP-capable client.

SNMP Access Control Click the SNMP Access Control button to display the SNMP Access Control screen for specifying which users can read SNMP-generated information and potentially modify related settings from an SNMP-capable client.

The SNMP Access Control screen's Access Control List (ACL) uses Internet Protocol (IP) addresses to restrict access to the AP???s SNMP interface. The ACL applies to both SNMP v3 user definitions and SNMP v1/v2c community definitions.

For detailed instructions of configuring SNMP user access and modification privileges, see Configuring SNMP Access Control on page 4-29.

5. If configuring SNMP v3 user definitions, set the SNMP v3 engine ID.

AP-51xx SNMP v3 The access point SNMP v3 Engine ID field lists the unique SNMP Engine IDv3 Engine ID for the access point. This ID is used in SNMP v3 as the

source for a trap, response or report. It is also used as the destination ID when sending get, getnext, getbulk, set or inform commands.

6.Click Apply to save any changes to the SNMP Access screen. Navigating away from the screen without clicking the Apply button results in all changes to the screen being lost.

???Configuring SNMP RF Trap Thresholds

4.5.1 Configuring SNMP Access Control

Use the SNMP Access Control screen (as launched from the SNMP Access screen) to specify which users can read SNMP generated information and, if capable, modify related settings from an SNMP-capable client.

Use the SNMP Access Control screen's Access Control List (ACL) to limit, by Internet Protocol (IP) address, who can access the access point SNMP interface.

NOTE The ACL applies to both SNMP v3 user definitions and SNMP v1/v2c community definitions on the access point SNMP Access screen.

To configure SNMP user access control for the access point:

1.Select System Configuration - > SNMP Access from the access point menu tree. Click on the SNMP Access Control button from within the SNMP Access screen.

4-30 AP-51xx Access Point Product Reference Guide

2.Configure the SNMP Access Control screen to add the IP addresses of those users receiving SNMP access.

System Configuration 4-31

4.5.2 Enabling SNMP Traps

SNMP provides the ability to send traps to notify the administrator that trap conditions are met. Traps are network packets containing data relating to network devices, or SNMP agents, that send the traps. SNMP management applications can receive and interpret these packets, and optionally can perform responsive actions. SNMP trap generation is programmable on a trap-by-trap basis.

Use the SNMP Traps Configuration screen to enable traps and to configure appropriate settings for reporting this information. Trap configuration depends on the network machine that receives the generated traps. SNMP v1/v2c and v3 trap configurations function independently. In a mixed SNMP environment, generated traps can be sent using configurations for both SNMP v1/v2c and v3.

To configure SNMP traps on the access point:

1.Select System Configuration - > SNMP Access - > SNMP Trap Configuration from the access point menu tree.

4-32 AP-51xx Access Point Product Reference Guide

2.Configure the SNMP v1/v2c Trap Configuration field (if SNMP v1/v2c Traps are used) to modify the following:

System Configuration 4-33

6.Click Logout to securely exit the access point Access Point applet. A prompt displays confirming the logout before the applet is closed.

4.5.3Configuring Specific SNMP Traps

Use the SNMP Traps screen to enable specific traps on the access point. Motorola recommends defining traps to capture unauthorized devices operating within the access point coverage area. Trap configuration depends on the network machine that receives the generated traps. SNMP v1/v2c and v3 trap configurations function independently. In a mixed SNMP environment, traps can be sent using configurations for both SNMP v1/v2c and v3. To configure specific SNMP traps on the access point:

1. Select System Configuration - > SNMP Access - > SNMP Traps from the menu tree.

System Configuration 4-35

2.Configure the MU Traps field to generate traps for MU associations, MU association denials and MU authentication denials. When a trap is enabled, a trap is sent every 10 seconds until the condition no longer exists.

3.Configure the SNMP Traps field to generate traps when SNMP capable MUs are denied authentication privileges or are subject of an ACL violation. When a trap is enabled, a trap is sent every 5 seconds until the condition no longer exists.

SNMP authentication Generates a trap when an SNMP-capable client is denied access failuresto the access point???s SNMP management functions or data. This

can result from an incorrect login, or missing/incorrect user credentials.

SNMP ACL violation Generates a trap when an SNMP client cannot access SNMP management functions or data due to an Access Control List (ACL) violation. This can result from a missing/incorrect IP address entered within the SNMP Access Control screen.

4.Configure the Network Traps field to generate traps when the access point???s link status changes or when the AP???s firewall detects a DOS attack.

4-38 AP-51xx Access Point Product Reference Guide

NOTE Average Bit Speed,% of Non-Unicast, Average Signal, Average Retries,% Dropped and % Undecryptable are not access point statistics.

3.Configure the Minimum Packets field to define a minimum packet throughput value for trap generation.

Minimum number of Enter the minimum number of packets that must pass through the

packets required for a device before an SNMP rate trap is sent. Motorola recommends trap to fireusing the default setting of 1000 as a minimum setting for the field.

4.Click Apply to save any changes to the SNMP RF Traps screen. Navigating away from the screen without clicking the Apply button results in all changes to the screen being lost.

System Configuration 4-39

6.Click Logout to securely exit the access point Access Point applet. A prompt displays confirming the logout before the applet is closed.

4.6Configuring Network Time Protocol (NTP)

Network Time Protocol (NTP) manages time and/or network clock synchronization in the access point- managed network environment. NTP is a client/server implementation. The access point (an NTP client) periodically synchronizes its clock with a master clock (an NTP server). For example, the access point resets its clock to 07:04:59 upon reading a time of 07:04:59 from its designated NTP server.

Time synchronization is recommended for the access point???s network operations. For sites using Kerberos authentication, time synchronization is required. Use the Date and Time Settings screen to enable NTP and specify the IP addresses and ports of available NTP servers.

NOTE The current time is not set accurately when initially connecting to the access point. Until a server is defined to provide the access point the correct time, or the correct time is manually set, the access point displays 1970-01-01 00:00:00 as the default time.

CAUTION If using the Radius time-based authentication feature to authenticate ! access point user permissions, ensure UTC has been selected from

the Date and Time Settings screen???s Time Zone field. If UTC is not selected, time based authentication will not work properly. For information on configuring Radius time-based authentication, see

Defining User Access Permissions by Group on page 6-76.

To manage clock synchronization on the access point:

1. Select System Configuration - > Date/Time from the access point menu tree.

4-40 AP-51xx Access Point Product Reference Guide

2.From within the Current Time field, click the Refresh button to update the time since the screen was displayed by the user.

The Current Time field displays the current time based on the access point system clock. If NTP is disabled or if there are no servers available, the system time displays the access point uptime starting at 1970-01-01 00:00:00, with the time and date advancing.

3.Select the Set Date/Time button to display the Manual Date/Time Setting screen.

This screen enables the user to manually enter the access point???s system time using a Year-Month-Day HH:MM:SS format.

This option is disabled when the Enable NTP checkbox has been selected, and therefore should be viewed as a second means to define the access point system time.

4.If using the Manual Date/Time Setting screen to define the access point???s system time, refer to the Time Zone field to select the time used to use as complimentary information to the information entered within the Manual Date/Time Setting screen.

System Configuration 4-41

CAUTION If using the Radius time-based authentication feature to authenticate ! access point user permissions, ensure UTC has been selected from

the Time Zone field. If UTC is not selected, time based authentication will not work properly. For information on configuring Radius time-based authentication, see Defining User Access Permissions by Group on page 6-76.

5.If using an NTP server to supply system time to the access point, configure the NTP Server Configuration field to define the server network address information required to acquire the access point network time.

6.Click Apply to save any changes to the Date and time Settings screen. Navigating away from the screen without clicking the Apply button results in all changes to the screen being lost.

7.Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on Date and Time Settings screen to the last saved configuration.

System Configuration 4-43

3.Click Apply to save any changes to the Logging Configuration screen. Navigating away from the screen without clicking the Apply button results in all changes to the screen being lost.

4-44 AP-51xx Access Point Product Reference Guide

4.Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on the Logging Configuration screen to the last saved configuration.

5.Click Logout to securely exit the access point Access Point applet. A prompt displays confirming the logout before the applet is closed.

4.8Importing/Exporting Configurations

All of the configuration settings for an access point can be obtained from another access point in the form of a text file. Additionally, all of the access point???s settings can be downloaded to another access point. Use the file-based configuration feature to speed up the setup process significantly at sites using multiple access points.

Another benefit is the opportunity to save the current AP configuration before making significant changes or restoring the default configuration. All options on the access point are deleted and updated by the imported file. Therefore, the imported configuration is not a merge with the configuration of the target access point. The exported file can be edited with any document editor if necessary.

NOTE Use the System Settings screen as necessary to restore an access point???s default configuration. For more information on restoring configurations, see Configuring System Settings on page 4-2.

The export function will always export the encrypted Admin User password. The import function will import the Admin Password only if the access point is set to factory default. If the access point is not configured to factory default settings, the Admin User password WILL NOT get imported.

NOTE When modifying the text file manually and spaces are used for wireless, security, MU policy names etc., ensure you use ???\20??? between the spaces. For example, ???Second\20Floor\20Lab???. When imported, the name would display as ???Second Floor Lab???.

CAUTION A single-radio model access point cannot import/export its

! configuration to a dual-radio model access point. In turn, a dual-radio model access point cannot import/export its configuration to a single- radio access point.

System Configuration 4-45

Use the Config Import/Export screen to configure an import or export operation for access point configuration settings.

CAUTION If importing a 1.1 baseline configuration onto the 2.0 baseline, the ! 802.1x EAP Radius shared secret password will remain ???symbol,???

instead of ???motorola??? (as now required with the 2.0 baseline).

If the shared secret password is not changed to ???motorola??? there will be a shared secret mis-match resulting in MU authentication failures. This password cannot be set using the access point Web UI, and must be changed using the CLI. For information on changing the shared secret password using the access point CLI, see

AP51xx>admin(network.wireless.security)> create on page 8-82.

CAUTION Motorola discourages importing a 1.0 baseline configuration file to a ! 1.1 version access point. Similarly, a 1.1 baseline configuration file

should not be imported to a 1.0 version access point. Importing configuration files between different version access point???s results in broken configurations, since new features added to the 1.1 version access point cannot be supported in a 1.0 version access point.

To create an importable/exportable access point configuration file:

1. Select System Configuration - > Config Import/Export from the access point menu tree.

4-46 AP-51xx Access Point Product Reference Guide

2. Configure the FTP and TFTP Import/Export field to import/export configuration settings.

System Configuration 4-47

3.Configure the HTTP Import/Export field to import/export access point configuration settings using HTTP.

4-48 AP-51xx Access Point Product Reference Guide

4. Refer to the Status field to assess the completion of the import/export operation.

Auto cfg update: Error in getting config file

Auto cfg update: Aborting due to fw update failure

The <number> value appearing at the end of some messages relates to the line of the configuration file where an error or ambiguous input was detected.

CAUTION If errors occur when importing the configuration file, a parsing

! message displays defining the line number where the error occurred. The configuration is still imported, except for the error. Consequently, it is possible to import an invalid configuration. The user is required to fix the problem and repeat the import operation until an error-free import takes place.

System Configuration 4-49

NOTE Motorola recommends importing configuration files using the CLI. If errors occur during the import process, they display all at once and are easier to troubleshoot. The access point GUI displays errors one at a time, and troubleshooting can be a more time-consuming process.

NOTE When importing the configuration, a xxxxxbytes loaded status message indicates the file was downloaded successfully. An Incompatible Hardware Type Error message indicates the configuration was not applied due to a hardware compatibility issue between the importing and exporting devices.

5.Click Apply to save the filename and Server IP information. The Apply button does not execute the import or export operation, only saves the settings entered.

6.Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on Config Import/Export screen to the last saved configuration.

7.Click Logout to securely exit the access point Motorola Access Point applet. A prompt displays confirming the logout before the applet is closed.

NOTE For a discussion on the implications of replacing an existing AP-4131 deployment with an AP-5131 or AP-5181, see Replacing an AP-4131 with an AP-5131 or AP-5181 on page B-20.

4.9 Updating Device Firmware

Motorola periodically releases updated versions of the access point device firmware to the Motorola Web site. If the access point firmware version displayed on the System Settings page (see Configuring System Settings on page 4-2) is older than the version on the Web site, Motorola recommends updating the access point to the latest firmware version for full feature functionality.

The access point???s automatic update feature updates the access point???s firmware and configuration file automatically when the access point is reset or when the access point initiates a DHCP request.

The firmware is automatically updated each time firmware versions are found to be different between what is running on the access point and the firmware file located on the server. The configuration file is automatically updated when the configuration file name on the server is different than the name of the file previously loaded on the access point or when the file version (on the server) is different than the version currently in use on the access point.

4-50 AP-51xx Access Point Product Reference Guide

Additionally, the configuration version can be manually changed in the text file to cause the configuration to be applied when required. The parameter name within the configuration file is ???cfg-version-1.1-01.??? The access point only checks the two characters after the third hyphen (01) when making a comparison. Change the last two characters to update the access point???s configuration. The two characters can be alpha-numeric.

Upgrading from a legacy to a new firmware version is a two step process requiring the same upgrade procedure to be repeated twice. The first upgrade will result in a bootloader change, and the second upgrade will result in the actual firmware update. For subsequent upgrades, a single download will suffice. Using Auto Update, the access point will automatically update itself twice when upgrading.

Upgrading to a new access point firmware baseline does not retain the configuration of the previous (lower version) firmware. Motorola recommends users export their 1.0 configuration for backup purposes prior to upgrading.

When downloading to a lower firmware version, all configuration settings are lost and the access point returns to factory default settings of the lower version.

CAUTION If downgrading firmware from to a lower version, the access point ! automatically reverts to default settings of the lower version,

regardless of whether you are downloading the firmware manually or using the automatic download feature. The automatic feature allows the user to download the configuration file at the same time, but since the firmware reverts to the default settings of the lower version, the configuration file is ignored.

NOTE An AP-5181 does not support any firmware versions prior to 1.1.1.0.

For detailed update scenarios involving both a Windows DHCP and a Linux BootP server

configuration, see Configuring Automatic Updates using a DHCP or Linux BootP Server on page B-1.

System Configuration 4-51

CAUTION Loaded and signed CA certificates will be lost when changing the ! access point???s firmware version using either the GUI or CLI. After a

certificate has been successfully loaded, export it to a secure location to ensure its availability after a firmware update.

If restoring the access point???s factory default firmware, you must export the certificate file BEFORE restoring the access point???s factory default configuration. Import the file back after the updated firmware is installed. For information on using the access point CLI to import and export the access point???s configuration, see

AP51xx>admin(system.cmgr)> impcert on page 8-167 and

AP51xx>admin(system.cmgr)> expcert on page 8-166.

If a firmware update is required, use the Firmware Update screen to specify a filename and define a file location for updating the firmware.

NOTE The firmware file must be available from an FTP or TFTP site to perform the update.

To conduct a firmware update on the access point:

1.Export the access point current configuration settings before updating the firmware to have the most recent settings available after the firmware is updated.

Refer to Importing/Exporting Configurations on page 4-44 for instructions on exporting the access point???s current configuration to have it available after the firmware is updated.

2.Select System Configuration - > Firmware Update from the access point menu tree.

4-52 AP-51xx Access Point Product Reference Guide

3.Configure the DHCP Options checkboxes to enable/disable automatic firmware and/or configuration file updates.

DHCP options are used for out-of-the-box rapid deployment for Motorola wireless products. The following are the two options available on the access point:

???Enable Automatic Firmware Update

???Enable Automatic Configuration Update

Both DHCP options are enabled by default.

These options can be used to update newer firmware and configuration files on the access point. For more information on how to configure a DHCP or BootP Server for the automatic upgrade process, see Usage Scenarios on page B-1.

The update is conducted over the LAN or WAN port depending on which server responds first to the access point???s request for an automatic update.

System Configuration 4-53

Enable Automatic Enable this checkbox to allow an automatic firmware update when Firmware Update firmware versions are found to be different between what is

running on the access point and the firmware that resides on the server. A firmware update will only occur if the access point is reset or when the access point does a DHCP request.

This feature is used in conjunction with DHCP/BootP options configured on a DHCP or BootP server. For more information, see

Usage Scenarios on page B-1.

If this checkbox is not enabled, the firmware update is required to be conducted manually.

Enable Automatic Select this checkbox to allow an automatic configuration update Configuration Update when the configuration filenames are found to be different

between the filename loaded on the access point and the configuration filename that resides on the server or when the configuration file versions are found to be different between the configuration file version loaded on the access point and the configuration file that resides on server. A configuration update will only occur if the access point is reset or when the access point does a DHCP request.

This feature is used in conjunction with DHCP/BootP options configured on a DHCP or BootP server. For more information, see

Usage Scenarios on page B-1.

If this checkbox is not enabled, the configuration update is required to be done manually.

CAUTION If using a Linux server configured to support the BootP ???bf??? option, an ! automatic firmware update is not be triggered unless both the Enable

Automatic Firmware Update and Enable Automatic Configuration Update options are selected. If the Configuration Update option is disabled, the access point will not download the configuration file. Without the configuration file, the access point cannot parse for the firmware file name required to trigger the firmware update.

If updating the access point manually, configure the Update Firmware fields as required to set a filename and target firmware file upload location for firmware updates.

4. Specify the name of the target firmware file within the Filename field.

4-54 AP-51xx Access Point Product Reference Guide

5.If the target firmware file resides within a directory, specify a complete path for the file within the Filepath(optional) field.

6.Enter an IP address for the FTP or TFTP server used for the update. Only numerical IP address names are supported, no DNS can be used.

7.Select FTP or TFTP to define whether the firmware file resides on a FTP or TFTP server.

8.Set the following FTP or TFTP parameters:

???Username - Specify a username for the FTP server login.

???Password - Specify a password for FTP server login. Default is motorola. A blank password is not supported.

NOTE Click Apply to save the settings before performing the firmware update. The user is not able to navigate the access point user interface while the firmware update is in process.

9.Click the Perform Update button to initiate the update. Upon confirming the firmware update, the AP reboots and completes the update.

NOTE The access point must complete the reboot process to successfully update the device firmware, regardless of whether the reboot is conducted using the GUI or CLI interfaces.

10.After the AP reboots, return to the Firmware Update screen. Check the Status field to verify whether the firmware update was successful. If an error occurs, one of the following error messages will display:

FAIL: auto fw update check

FAIL: network activity time out

FAIL: firmware check

FAIL: exceed memory limit

FAIL: invalid subnet number

11.Confirm the access point configuration is the same as it was before the firmware update. If they are not, restore the settings. Refer to Importing/Exporting Configurations on page 4-44 for instructions on exporting the configuration back to the access point.

12.Click Apply to save the filename and filepath information entered into the Firmware Update screen. The Apply button does not execute the firmware, only saves the update settings entered.

13.Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on Firmware Update screen to the last saved configuration.

14.Click Logout to securely exit the access point Access Point applet. A prompt displays confirming the logout before the applet is closed.

4.9.1Upgrade/Downgrade Considerations

When upgrading or downgrading access point configurations between the 1.0.0.0-xx (or 1.0.1.0-xx) and 1.1.0.0-xx baselines, the following should be taken into consideration as certain functionalities may not be available to the user after an upgrade/downgrade:

CAUTION Prior to upgrading/downgrading the access point???s configuration,

! ensure the access point???s current configuration has been exported to a secure location. Having the configuration available is recommended in case errors occur in the upgrade/downgrade process.

???When downgrading from 1.1.1/1.1 to 1.0, the access point is configured to default values.

???After a downgrade from 1.1/1.1.0 to 1.0.x.x, WLANs mapped to LAN2 would still be usable, but now only available on LAN1. Once upgraded back, those WLANs previously available on LAN2 would still be mapped to LAN2.

???If downgraded to the 1.0.0.0-xx baseline, and a restore factory defaults function is performed, only 1.0.0.0-xx default values are restored to their factory default values. The feature set unique to 1.1/1.1.1 can only be restored to factory default when the access point is running 1.1.0.0-xx firmware.

???An AP-5181 model access point does not support firmware prior to 1.1.1.0.

4-56 AP-51xx Access Point Product Reference Guide

???Export either a CA or Self Certificate to a safe and secure location before upgrading or downgrading your access point firmware. If the certificate is not saved, it will be discarded and not available to the user after the upgrade or downgrade. If discarded, a new certificate request would be required.

NOTE For a discussion on the implications of replacing an existing AP-4131 deployment with an AP-5131 or AP-5181, see Replacing an AP-4131 with an AP-5131 or AP-5181 on page B-20.

???Upgrading from v1.0.x.x to 1.1.x.x/1.1.1 is a two step process requiring the same upgrade procedure to be repeated twice. The first upgrade will result in a bootloader change, and the second upgrade will result in a firmware change. For subsequent upgrades, a single download will suffice. Using Auto Update, the access point will automatically update itself twice when upgrading. Upgrading from v1.0 to v1.1/v1.1.1 retains existing settings. Motorola recommends that users export their 1.0 configuration for backup purposes prior to upgrading. When downloading from v1.1.1/v1.1 to v1.0, all configuration settings are lost and the access point returns to factory default settings.

Network Management

Refer to the following for network management configuration activities supported by the access point user interface:

???Configuring the LAN Interface

???Configuring WAN Settings

???Enabling Wireless LANs (WLANs)

???Configuring Router Settings

5.1Configuring the LAN Interface

The access point has one physical LAN port supporting two unique LAN interfaces. The access point LAN port has its own MAC address. The LAN port MAC address is always the value of the access point WAN port MAC address plus 1. The LAN and WAN port MAC addresses can be located within the LAN and WAN Stats screens.

For information on locating the access point???s MAC addresses, see Viewing WAN Statistics on page 7-2 and Viewing LAN Statistics on page 7-6.

5-2 AP-51xx Access Point Product Reference Guide

Use the LAN Configuration screen to enable one (or both) of the access point???s LAN interfaces, assign them names, define which LAN is currently active on the access point Ethernet port and assign a timeout value to disable the LAN connection if no data traffic is detected within a defined interval.

To configure the access point LAN interface:

1. Select Network Configuration -> LAN from the access point menu tree.

2.Configure the LAN Settings field to enable the access point LAN1 and/or LAN2 interface, assign a timeout value, enable 802.1q trunking, configure WLAN mapping and enable 802.1x port authentication.

Network Management 5-3

3.Refer to the LAN Ethernet Timeout field to define how LAN Ethernet inactivity is processed by the access point.

Use the Ethernet Port Timeout drop-down menu to define how the access point interprets inactivity for the LAN assigned to the Ethernet port. When Enabled is selected, the access point uses the value defined in the Sec. box (default is 30 seconds). Selecting Disabled allows the LAN to use the Ethernet port for an indefinite timeout period.

4.Refer to the 802.1x Port Authentication field if using port authentication over the access point???s LAN port.

The access point only supports 802.1x authentication over its LAN port. The access point behaves as an 802.1x supplicant to authenticate to a server on the network. If using 802.1x authentication, enter the authentication server user name and password. The default password is ???motorola.???

5.1.1 Configuring VLAN Support

A Virtual Local Area Network (VLAN) is a means to electronically separate data on the same access point from a single broadcast domain into separate broadcast domains. The access point can group devices on one or more WLANs so that they can communicate as if they were attached to the same wire, when in fact they are located on a different LAN segment. Because VLANs are based on logical instead of physical connections, they are extremely flexible. By using a VLAN, you can group by logical function instead of physical location. A maximum of 16 VLANs can be supported on the access point (regardless of the access point being single or dual-radio model). An administrator can map 16 WLANs to 16 VLANs and enable or disable dynamic VLAN assignment.

VLANs enable organizations to share network resources in various network segments within large areas (airports, shopping malls, etc.). A VLAN is a group of clients with a common set of requirements independent of their physical location. VLANs have the same attributes as physical LANs, but they enable system administrators to group MUs even when they are not members of the same network segment.

NOTE A WLAN supporting a mesh network does not need to be assigned to a particular VLAN, as all the traffic proliferating the mesh network is already trunked. However, if MUs are to be connected to the Mesh WLAN, the WLAN will need to be tied to a VLAN.

The access point assignment of VLANs can be implemented using Static or Dynamic assignments (often referred to as memberships) for individual WLANs. Both methods have their advantages and disadvantages. Static VLAN membership is perhaps the most widely used method because of the relatively small administration overhead and security it provides. With Static VLANs, you manually assign individual WLANs to individual VLANs.

Although static VLANs are the most common form of VLAN assignments, dynamic VLAN assignment is possible per WLAN. Configuring dynamic VLANs entail the access point sending a DHCP request for device information (such as an IP address). Additional information (such as device MAC address information) is sent to the access point. The access point sends this MAC address to a host housing a copy of the Dynamic VLAN database. This database houses the records of MAC addresses and VLAN assignments. The VLAN database looks up the MAC to determine what VLAN is assigned to it. If it is not in the database, it simply uses a default VLAN assignment. The VLAN assignment is sent to the access point. The access point then maps the target WLAN for the assigned VLAN and traffic passes normally, allowing for the completion of the DHCP request and further traffic.

To create new VLANs or edit the properties of an existing VLAN:

5-6 AP-51xx Access Point Product Reference Guide

1.Select Network Configuration -> LAN from the access point menu tree.

2.Ensure the Enable 802.1q Trunking button is selected from within the LAN Setting field.

Trunk links are required to pass VLAN information between destinations. A trunk port is by default a member of all the VLANs existing on the access point and carry traffic for all those VLANs. Trunking is a function that must be enabled on both sides of a link.

3.Select the VLAN Name button.

The VLAN name screen displays. The first time the screen is launched a default VLAN name of 1 and a default VLAN ID of 1 display. The VLAN name is auto-generated once the user assigns a VLAN ID. However, the user has the option of re-assigning a name to the VLAN using New VLAN and Edit VLAN screens.

To create a new VLAN, click the Add button, to edit the properties of an existing VLAN, click the Edit button.

Network Management 5-7

4.Assign a unique VLAN ID (from 1 to 4095) to each VLAN added or modified.

The VLAN ID associates a frame with a specific VLAN and provides the information the access point needs to process the frame across the network. Therefore, it may be practical to assign a name to a VLAN representative or the area or type of network traffic it represents.

A business may have offices in different locations and want to extend an internal LAN between the locations. An access point managed infrastructure could provide this connectivity, but it requires VLAN numbering be managed carefully to avoid conflicts between two VLANs with the same ID.

5.Define a 32 ASCII character maximum VLAN Name.

Enter a unique name that identifies members of the VLAN. Motorola recommends selecting the name carefully, as the VLAN name should signify a group of clients with a common set of requirements independent of their physical location.

6.Click Apply to save the changes to the new or modified VLAN.

7.From the LAN Configuration screen, click the WLAN Mapping button. The Mapping Configuration screen displays.

5-8 AP-51xx Access Point Product Reference Guide

8.Enter a Management VLAN Tag for LAN1 and LAN2.

The Management VLAN uses a default tag value of 1. The Management VLAN is used to distinguish VLAN traffic flows for the LAN. The trunk port marks the frames with special tags as they pass between the access point and its destination, these tags help distinguish data traffic.

Authentication servers (such as Radius and Kerberos) must be on the same Management VLAN. Additionally, DHCP and BOOTP servers must be on the same Management VLAN as well.

9.Define a Native VLAN Tag for LAN1 and LAN2.

A trunk port configured with 802.1Q tagging can receive both tagged and untagged traffic. By default, the access point forwards untagged traffic with the native VLAN configured for the port. The Native VLAN is VLAN 1 by default. Motorola suggests leaving the Native VLAN set to 1 as other layer 2 devices also have their Native VLAN set to 1.

10.Use the LAN drop-down menu to map one of the two LANs to the WLAN listed to the left. With this assignment, the WLAN uses this assigned LAN interface.

11.Select the Dynamic checkboxes (under the Mode column) to configure the VLAN mapping as a dynamic VLAN.

Using Dynamic VLAN assignments, a VMPS (VLAN Management Policy Server) dynamically assigns VLAN ports. The access point uses a separate server as a VMPS server. When a

Network Management 5-9

frame arrives on the access point, it queries the VMPS for the VLAN assignment based on the source MAC address of the arriving frame.

If statically mapping VLANs, leave the Dynamic checkbox specific to the target WLAN and its intended VLAN unselected. The administrator is then required to configure VLAN memberships manually.

The Dynamic checkbox is enabled only when a WLAN is having EAP configured. Otherwise, the checkbox is disabled.

12.Use the VLAN drop-down menu to select the name of the target VLAN to map to the WLAN listed on the left-hand side of the screen.

Motorola recommends mapping VLANs strategically in order to keep VLANs tied to the discipline they most closely match. For example, If WLAN1 is comprised of MUs supporting the sales area, then WLAN1 should be mapped to sales if a sales VLAN has been already been created.

13.Click Apply to return to the VLAN Name screen. Click OK to return to the LAN screen. Once at the LAN screen, click Apply to re-apply your changes.

5.1.2Configuring LAN1 and LAN2 Settings

Both LAN1 and LAN2 have separate sub-screens to configure the DHCP settings used by the LAN1 and LAN2 interfaces. Within each LAN screen is a button to access a sub-screen to configure advanced DHCP settings for that LAN. For more information, see Configuring Advanced DHCP Server Settings on page 5-12. Additionally, LAN1 and LAN2 each have separate Type Filter submenu items used to prevent specific (an potentially unneccesary) frames from being processed, for more information, see Setting the Type Filter Configuration on page 5-14.

To configure unique settings for either LAN1 or LAN2:

1.Select Network Configuration -> LAN -> LAN1 (or LAN2) from the access point menu tree.

5-10 AP-51xx Access Point Product Reference Guide

2. Configure the DHCP Configuration field to define the DHCP settings used for the LAN.

NOTE Motorola recommends the WAN and LAN ports should not both be configured as DHCP clients.

This interface is a Select this button to enable DHCP to set network address DHCP Client information via this LAN1 or LAN2 connection. This is

recommended if the access point resides within a large corporate network or the Internet Service Provider (ISP) uses DHCP. This setting is enabled for LAN1 by default.

DHCP is a protocol that includes mechanisms for IP address allocation and delivery of host-specific configuration parameters from a DHCP server to a host. If DHCP Client is selected, the first DHCP or BOOTP server to respond sets the IP address and network address values since DHCP and BOOTP are interoperable.

5.1.2.1 Configuring Advanced DHCP Server Settings

Use the Advanced DHCP Server screen to specify (reserve) static (or fixed) IP addresses for specific devices. Every wireless, 802.11x-standard device has a unique Media Access Control (MAC) address. This address is the device's hard-coded hardware number (shown on the bottom or back). An example of a MAC address is 00:A0:F8:45:9B:07.

The DHCP server can grant an IP address for as long as it remains in active use. The lease time is the number of seconds an IP address is reserved for re-connection after its last use. Using very short leases, DHCP can dynamically reconfigure networks in which there are more computers than available IP addresses. This is useful, for example, in education and customer environments where MU users change frequently. Use longer leases if there are fewer users.

Network Management 5-13

To generate a list of client MAC address to IP address mappings for the access point:

1.Select Network Configuration -> LAN -> LAN1 (or LAN2) from the access point menu tree.

2.Click the Advanced DHCP Server button from within the LAN1 or LAN2 screen.

3.Specify a lease period in seconds for available IP addresses using the DHCP Lease Time (Seconds) parameter. An IP address is reserved for re-connection for the length of time you specify. The default interval is 86400 seconds.

4.Click the Add button to create a new table entry within the Reserved Clients field.

If a statically mapped IP address is within the IP address range in use by the DHCP server, that IP address may still be assigned to another client. To avoid this, ensure all statically mapped IP addresses are outside of the IP address range assigned to the DHCP server.

If multiple entries exist within the Reserved Clients field, use the scroll bar to the right of the window to navigate.

5.Click the Del (delete) button to remove a selected table entry.

7.Click Cancel to undo any changes made. Undo Changes reverts the settings displayed to the last saved configuration.

5.1.2.2 Setting the Type Filter Configuration

Each access point LAN (either LAN1 or LAN2) can keep a list of frame types that it forwards or discards. The Type Filtering feature prevents specific (a potentially unneccesary) frames from being processed by the access point in order to improve throughput. These include certain broadcast frames from devices that consume bandwidth, but are unnecessary to access point operations.

Use the Ethernet Type Filter Configuration screen to build a list of filter types and configure them as either allowed or denied for use with the this particular LAN.

To configure type filtering on the access point:

1.Select Network Configuration-> LAN -> LAN1 (or LAN2)-> Type Filter from the access point menu tree.

The Ethernet Type Filter Configuration screen displays for the LAN. No Ethernet types are displayed (by default) when the screen is first launched.

Network Management 5-15

2.Use the all ethernet types, except drop-down menu to designate whether the Ethernet Types defined for the LAN are allowed or denied for use by the access point.

3.To add an Ethernet type, click the Add button.

The Add Ethernet Type screen displays. Use this screen to add one type filter option at a time, for a list of up to 16 entries.

5-16 AP-51xx Access Point Product Reference Guide

Packet types supported for the type filtering function include 16-bit DIX Ethernet types as well as Motorola proprietary types. Select an Ethernet type from the drop down menu, or enter the Ethernet type???s hexadecimal value. See your System Administrator if unsure of the implication of adding or omitting a type from the list for either LAN1 or LAN2.

4.To optionally delete a type filtering selection from the list, highlight the packet type and click the Delete button.

5.Click Apply to save any changes to the LAN1 or LAN2 Ethernet Type Filter Configuration screen. Navigating away from the screen without clicking Apply results in all changes to the screens being lost.

6.Click Cancel to securely exit the LAN1 or LAN2 Ethernet Type Filter Configuration screen without saving your changes.

7.Click Logout to securely exit the Access Point applet. A prompt displays confirming the logout before the applet is closed.

5.2Configuring WAN Settings

A Wide Area Network (WAN) is a widely dispersed telecommunications network. The access point includes one WAN port. The access point WAN port has its own MAC address. In a corporate environment, the WAN port might connect to a larger corporate network. For a small business, the WAN port might connect to a DSL or cable modem to access the Internet.

Use the WAN screen to set the WAN IP configuration and Point-to-Point Protocol over Ethernet (PPPoE) parameters.

To configure WAN settings for the access point:

1. Select Network Configuration -> WAN from the access point menu tree.

Network Management 5-17

2.Refer to the WAN IP Configuration field to enable the WAN interface, and set network address information for the WAN connection.

NOTE Motorola recommends that the WAN and LAN ports should not both be configured as DHCP clients.

Enable WAN Interface Select the Enable WAN Interface checkbox to enable a connection between the access point and a larger network or outside world through the WAN port.

Disable this option to effectively isolate the access point???s WAN. No connections to a larger network or the Internet are possible. MUs cannot communicate beyond the LAN.

By default, the WAN port is static with an IP address of 10.1.1.1.

5-18 AP-51xx Access Point Product Reference Guide

Network Management 5-19

3.Use the Port Settings field to define how the access point manages throughput over the WAN port.

5-20 AP-51xx Access Point Product Reference Guide

4.Configure the PPP over Ethernet field to enable high speed dial-up connections to the access point WAN port.

Network Management 5-21

Idle Time (seconds) Specify an idle time in seconds to limit how long the access point???s WAN connection remains active after outbound and inbound traffic is not detected. The Idle Time field is grayed out if Keep-Alive is enabled.

Authentication Type Use the Authentication Type menu to specify the authentication protocol(s) for the WAN connection. Choices include None, PAP or CHAP, PAP, or CHAP.

Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP) are competing identify-verification methods.

PAP sends a username and password over a network to a server that compares the username and password to a table of authorized users. If the username and password are matched in the table, server access is authorized. WatchGuard products do not support the PAP protocol because the username and password are sent as clear text that a hacker can read.

CHAP uses secret information and mathematical algorithms to send a derived numeric value for login. The login server knows the secret information and performs the same mathematical operations to derive a numeric value. If the results match, server access is authorized. After login, one of the numbers in the mathematical operation is changed to secure the connection. This prevents any intruder from trying to copy a valid authentication session and replaying it later to log in.

5.Click Apply to save any changes to the WAN screen. Navigating away from the screen without clicking the Apply button results in all changes to the screen being lost.

6.Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on the WAN screen to the last saved configuration.

7.Click Logout to securely exit the Access Point applet. A prompt displays confirming the logout before the applet is closed.

5.2.1Configuring Network Address Translation (NAT) Settings

Network Address Translation (NAT) converts an IP address in one network to a different IP address or set of IP addresses in another network. The access point router maps its local (inside) network addresses to WAN (outside) IP addresses, and translates the WAN IP addresses on incoming packets to local IP addresses. NAT is useful because it allows the authentication of incoming and outgoing

5-24 AP-51xx Access Point Product Reference Guide

5.Click OK to return to the NAT screen. Within the NAT screen, click Apply to save any changes made on the Port Forwarding screen.

6.Click Cancel to undo any changes made on Port Forwarding screen. This reverts all settings for the Port Forwarding screen to the last saved configuration.

5.2.2Configuring Dynamic DNS

The access point supports the Dynamic DNS service. Dynamic DNS (or DynDNS) is a feature offered by www.dyndns.com which allows the mapping of domain names to dynamically assigned IP addresses via the WAN port. When the dynamically assigned IP address of a client changes, the new IP address is sent to the DynDNS service and traffic for the specified domain(s) is routed to the new IP address.

NOTE DynDNS supports only the primary WAN IP address.

To configure dynamic DNS for the access point:

1. Select Network Configuration -> WAN -> DynDNS from the access point menu tree.

5-26 AP-51xx Access Point Product Reference Guide

5.3Enabling Wireless LANs (WLANs)

A Wireless Local Area Network (WLAN) is a data-communications system that flexibly extends the functionalities of a wired LAN. A WLAN does not require lining up devices for line-of-sight transmission, and are thus, desirable. Within the WLAN, roaming users can be handed off from one access point to another like a cellular phone system. WLANs can therefore be configured around the needs of specific groups of users, even when they are not in physical proximity.

Use the access point???s Wireless Configuration screen to create new WLANs, edit the properties of existing WLANs or delete a WLAN to create space for a new WLAN. Sixteen WLANs are available on the access point (regardless of single or dual-radio model).

To configure WLANs on the access point:

1. Select Network Configuration -> Wireless from the access point menu tree.

5-28 AP-51xx Access Point Product Reference Guide

If a WLAN is defined, that WLAN displays within the Wireless Configuration screen. When the access point is first booted, WLAN1 exists as a default WLAN available immediately for connection.

2.Refer to the information within the Wireless Configuration screen to view the name, ESSID, access point radio designation, VLAN ID and security policy of existing WLANs.

Network Management 5-29

3.Click the Create button (if necessary) to launch the New WLAN screen. Use the New WLAN screen to define the properties of a new WLAN that would display and be selectable within the Wireless Configuration screen. For additional information, see Creating/ Editing Individual WLANs on page 5-30.

2. Click Logout to exit the Security Configuration screen.

5.3.1.2 Configuring a WLAN Access Control List (ACL)

An Access Control List (ACL) affords a system administrator the ability to grant or restrict MU access by specifying a MU MAC address or range of MAC addresses to either include or exclude from access point connectivity. Use the Mobile Unit Access Control List Configuration screen to create new ACL policies (using the New MU ACL Policy sub-screen) or edit existing policies (using the Edit MU ACL Policy sub-screen). Once new policies are defined, they are available for use within the New WLAN or Edit WLAN screens to assign to specific WLANs based on MU interoperability requirements.

Motorola recommends using the New MU ACL Policy or Edit MU ACL Policy screens strategically to name and configure ACL policies meeting the requirements of the particular WLANs they may map to. However, be careful not to name policies after specific WLANs, as individual ACL policies can be used by more than one WLAN. For detailed information on assigning ACL policies to specific WLANs, see Creating/Editing Individual WLANs on page 5-30.

To create or edit ACL policies for WLANs:

1.Select Network Configuration -> Wireless -> MU ACL from the access point menu tree.

The Mobile Unit Access Control List Configuration screen displays with existing ACL policies and their current WLAN (if mapped to a WLAN).

NOTE When the access point is first launched, a single ACL policy (default) is available and mapped to WLAN 1. It is anticipated numerous additional ACL policies will be created as the list of WLANs grows.

Network Management 5-37

2.Click the Create button to configure a new ACL policy, or select a policy and click the Edit button to modify an existing ACL policy. The access point supports a maximum of 16 MU ACL policies.

5-38 AP-51xx Access Point Product Reference Guide

Either the New MU ACL Policy or Edit MU ACL Policy screens display.

3.Assign a name to the new or edited ACL policy that represents an inclusion or exclusion policy specific to a particular type of MU traffic you may want to use with a single or group of WLANs. More than one WLAN can use the same ACL policy.

4.Configure the parameters within the Mobile Unit Access Control List field to allow or deny MU access to the access point.

The MU adoption list identifies MUs by their MAC address. The MAC address is the MU's unique Media Access Control number printed on the device (for example, 00:09:5B:45:9B:07) by the manufacturer. A maximum of 200 MU MAC addresses can be added to the New/Edit MU ACL Policy screen.

Access for the listed Use the drop-down list to select Allow or Deny. This rule applies Mobile Units to the MUs listed in the table. For example, if the adoption rule is to Allow, access is granted for all MUs except those listed in the

table.

5.3.1.3 Setting the WLAN Quality of Service (QoS) Policy

The access point can keep a list of QoS policies that can be used from the New WLAN or Edit WLAN screens to map to individual WLANs. Use the Quality of Service Configuration screen to configure WMM policies that can improve the user experience for audio, video and voice applications by shortening the time between packet transmissions for higher priority (multimedia) traffic.

Use the Quality of Service Configuration screen to define the QoS policies for advanced network traffic management and multimedia applications support. If the existing QoS policies are insufficient, a new policy can be created or an existing policy can be modified using the New QoS Policy or Edit QoS Policy screens. Once new policies are defined, they are available for use within the New WLAN or Edit WLAN screens to assign to specific WLANs based on MU interoperability requirements.

Motorola recommends using the New QoS Policy and Edit QoS Policy screens strategically to name and configure QoS policies meeting the requirements of the particular WLANs they may to. However, be careful not to name policies after specific WLANs, as individual QoS policies can be used by more than one WLAN. For detailed information on assigning QoS policies to specific WLANs, see

Creating/Editing Individual WLANs on page 5-30.

To configure QoS policies:

1.Select Network Configuration -> Wireless -> QoS from the access point menu tree.

The Quality of Service Configuration screen displays with existing QoS policies and their current WLAN (if mapped to a WLAN).

5-40 AP-51xx Access Point Product Reference Guide

NOTE When the access point is first launched, a single QoS policy (default) is available and mapped to WLAN 1. It is anticipated additional QoS policies will be created as the list of WLANs grows.

2.Click the Create button to configure a new QoS policy, or select a policy and click the Edit button to modify an existing QoS policy. The access point supports a maximum of 16 QoS policies.

Network Management 5-41

3.Assign a name to the new or edited QoS policy that makes sense to the access point traffic receiving priority. More than one WLAN can use the same QoS policy.

4.Select the Support Voice prioritization checkbox to allow legacy voice prioritization.

Certain products may not receive priority over other voice or data traffic. Consequently, ensure the Support Voice Prioritization checkbox is selected if using products that do not support Wi-Fi Multimedia (WMM) to provide preferred queuing for these VOIP products.

If the Support Voice Prioritization checkbox is selected, the access point will detect non- WMM capable (legacy) phones that connect to the access point and provide priority queueing for their traffic over normal data.

NOTE Wi-fi functionality requires both the access point and its associated clients are WMM-capable and have WMM enabled. WMM enabled devices can take advantage of their QoS functionality only if using applications that support WMM, and can assign an appropriate priority level to the traffic streams they generate.

5-42 AP-51xx Access Point Product Reference Guide

5.Use the two Multicast Address fields to specify one or two MAC addresses to be used for multicast applications. Some VoIP devices make use of multicast addresses. Using this mechanism ensures that the multicast packets for these devices are not delayed by the packet queue.

6.Use the drop-down menu to select the radio traffic best representing the network requirements of this WLAN. Options include:

CAUTION Motorola recommends using the drop-down menu to define the

! intended radio traffic within the WLAN. Once an option is selected, you do not need to adjust the values for the Access Categories, unless qualified to do so. Changing the Access Category default values could negatively impact the performance of the access point.

U-APSD (WMM Power Save) Support

The access point now supports Unscheduled Automatic Power Save Delivery (U-APSD), often referred to as WMM Power Save. U-APSD provides a periodic frame exchange between a voice capable MU and the access point during a VoIP call, while legacy power management is still utilized for typical data frame exchanges. The access point and its associated MU activate the new U-APSD power save approach when a VoIP traffic stream is detected. The MU then buffers frames from the voice traffic stream and sends a VoIP frame with an implicit "poll" request to its associated access point. The access point responds to the poll request with buffered VoIP stream frame(s). When a voice-enabled MU wakes up at a designated VoIP frame interval, it sends a VoIP frame with an implicit "poll" request to its associated access point. The access point responds to the poll request with buffered VoIP stream frame(s).

NOTE The access point ships with the U-APSD feature disabled by default. It is automatically enabled when WMM is enabled for a WLAN. Thus, U-APSD is only functional when WMM is enabled. If WMM is disabled, then U-APSD is disabled as well.

Network Management 5-45

5.3.1.4 Configuring WLAN Hotspot Support

The access point enables hotspot operators to provide user authentication and accounting without a special client application. The access point uses a traditional Internet browser as a secure authentication device. Rather than rely on built-in 802.11security features to control access point association privileges, configure a WLAN with no WEP (an open network). The access point issues an IP address to the user using a DHCP server, authenticates the user and grants the user to access the Internet.

When a user visits a public hotspot and wants to browse to a Web page, they boot up their laptop and associate with the local Wi-Fi network by entering the correct SSID. They then start a browser. The hotspot access controller forces this un-authenticated user to a Welcome page from the hotspot Operator that allows the user to login with a username and password.

The access point hotspot functionality requires the following:

???HTTP Redirection - Redirects unauthenticated users to a specific page specified by the Hotspot provider.

???User authentication - Authenticates users using a Radius server.

???Walled garden support - Enables a list of IP address (not domain names) accessed without authentication.

???Billing system integration - Sends accounting records to a Radius accounting server.

CAUTION When using the access point???s hotspot functionality, ensure MUs are ! re-authenticated when changes are made to the characteristics of a

hotspot enabled WLAN, as MUs within the WLAN will be dropped from access point device association.

To configure hotspot functionality for an access point WLAN:

1.Ensure the Enable Hotspot checkbox is selected from within the target WLAN screen, and ensure the WLAN is properly configured.

Any of the sixteen WLANs on the access point can be configured as a hotspot. For hotspot enabled WLANs, DHCP, DNS,HTTP and HTTP-S traffic is allowed (before you login to the hotspot), while TCP/IP packets are redirected to the port on the subnet to which the WLAN is mapped. For WLANs not hotspot-enabled, all packets are allowed.

2.Click the Configure Hotspot button within the WLAN screen to display the Hotspot Configuration screen for that target WLAN.

5-46 AP-51xx Access Point Product Reference Guide

3.Refer to the HTTP Redirection field to specify how the Login, Welcome, and Fail pages are maintained for this specific WLAN. The pages can be hosted locally or remotely.

.

Use Default Files Select the Use Default Files checkbox if the login, welcome and fail pages reside on the access point.

Network Management 5-47

Use External URL Select the Use External URL checkbox to define a set of external URLs for hotspot users to access the login, welcome and fail pages. To create a redirected page, you need to have a TCP termination locally. On receiving the user credentials from the login page, the access point connects to a radius server, determines the identity of the connected wireless user and allows the user to access the Internet based on successful authentication.

4.Use the External URL field to specify the location of the login page, welcome page and fail

page used for hotspot access. Defining these settings is required when the Use External URL checkbox has been selected within the HTTP Redirection field.

NOTE If an external URL is used, the external Web pages are required to forward user credentials to the access point, which in turn forwards them to the authentication Server (either onboard or external server) in order to grant users Web access.

5.Select the Enable Hotspot User Timeout checkbox to define a timeout interval forcing users (when exceeded) to re-establish their login credentials to continue using the access point supported hotspot.

Leaving the checkbox unselected is not recommended unless you plan to provide unlimited hotspot support to users.

If this option is selected, enter an interval (between 15 and 180 minutes). When the provided interval is exceeded, the user is logged out of their hotspot session and forced to login to the hotspot again to access to the hotspot supported WLAN. The default timeout interval is 15 minutes.

5-48 AP-51xx Access Point Product Reference Guide

NOTE The Enable Hotspot User Timeout option is only available if using the access point???s internal Radius Server for user authentication.

6.Click the White List Entries button (within the WhiteList Configuration field) to create a set of allowed destination IP addresses. These allowed destination IP addresses are called a White List. Ten configurable IP addresses are allowed for each WLAN. For more information, see Defining the Hotspot White List on page 5-49.

NOTE If using an external Web Server over the WAN port, and the hotspot???s HTTP pages (login or welcome) redirect to the access point???s WAN IP address for CGI scripts, the IP address of the external Web server and the access point???s WAN IP address should be entered in the White List.

7.Refer to the Radius Accounting field to enable Radius accounting and specify the a timeout and retry value for the Radius server.

Network Management 5-49

8.Refer to the Radius Configuration field to define a primary and secondary Radius server port and shared secret password.

9.Click OK to save any changes to the Hotspot Configuration screen. Navigating away from the screen without clicking Apply results in all changes to the screens being lost.

10.Click Cancel (if necessary) to undo any changes made. Cancel reverts the settings displayed on the Hotspot Configuration screen to the last saved configuration.

Defining the Hotspot White List

To host a Login, Welcome or Fail page on the external Web server, the IP address of that Web server should be in access point???s White List.

NOTE If using an external Web Server over the WAN port, and the hotspot???s HTTP pages (login or welcome) redirect to the access point???s WAN IP address for CGI scripts, the IP address of the external Web server and the access point???s WAN IP address should be entered in the White List.

5-50 AP-51xx Access Point Product Reference Guide

When a client requests a URL from a Web server, the login handler returns an HTTP redirection status code (for example, 301 Moved Permanently), which indicates to the browser it should look for the page at another URL. This other URL can be a local or remote login page (based on the hotspot configuration). The login page URL is specified in the location???s HTTP header.

To host a Login page on the external Web server, the IP address of the Web server should be in the White list (list of IP addresses allowed to access the server) configuration. Ensure the Login page is designed so the submit action always posts the login data on the access point.

To define the White List for a target WLAN:

1.Click the White List Entries button from within the WLAN???s Hotspot Config screen.

2.Click the Add button to define an IP address for an allowed destination IP address.

3.Select a White List entry and click the Del button to remove the address from the White List.

4.Click OK to return to the Hotspot Config screen where the configuration can be saved by clicking the Apply button.

Now user enters his/her credentials on Login page and submits the page. Login Handler will execute a CGI script, which will use this data as input.

5.Click Cancel to return to the Hotspot Config screen without saving any of the White List entries defined within the White List Entries screen.

5.3.2 Setting the WLAN???s Radio Configuration

Each access point WLAN can have a separate 802.11a or 802.11b/g radio configured and mapped to that WLAN. The first step is to enable the radio.

One of two possible radio configuration pages are available on the access point depending on which model SKU is purchased. If the access point is a single-radio model, the Radio Configuration screen enables you to configure the single radio for either 802.11a or 802.11b/g use. The Radio Configuration screen contains two radio buttons whose selection is mutually exclusive.

If the access point is a dual-radio model, the Radio Configuration screen enables you to configure one radio for 802.11a use and the other for 802.11b/g (no other alternatives exist for the dual-radio model). Using a dual-radio access point, individual 802.11a and 802.11b/g radios can be enabled or disabled using the Radio Configuration screen checkboxes.

NOTE This section describes mesh networking (setting the radio???s base and client bridge configuration) at a high level. For a detailed overview on the theory of mesh networking, see Mesh Networking Overview on page 9-1. For detailed information on the implications of setting the mesh network configuration, see Configuring Mesh Networking Support on page 9-6. To review mesh network deployment scenarios, see Mesh Network Deployment - Quick Setup on page 9-20.

The Radio Configuration screen displays with two tabs. One tab each for the access point???s radios. Verify both tabs are selected and configured separately to enable the radio(s), and set their mesh networking definitions.

To set the access point radio configuration (this example is for a dual-radio access point):

1.Select Network Configuration -> Wireless -> Radio Configuration from the access point menu tree.

5-52 AP-51xx Access Point Product Reference Guide

2.Enable the radio(s) using the Enable checkbox(es).

Refer to RF Band of Operation parameter to ensure you are enabling the correct 802.11a or 802.11b/g radio. After the settings are applied within this Radio Configuration screen, the Radio Status and MUs connected values update. If this is an existing radio within a mesh network, these values update in real-time.

CAUTION If a radio is disabled, be careful not to accidentally configure a new ! WLAN, expecting the radio to be operating when you have forgotten it

was disabled.

3.Select the Base Bridge checkbox to allow the access point radio to accept client bridge connections from other access points in client bridge mode. The base bridge is the acceptor of mesh network data from those client bridges within the mesh network and never the initiator.

Network Management 5-53

4.If the Base Bridge checkbox has been selected, use the Max# Client Bridges parameter to define the client bridge load on a particular base bridge.

The maximum number of client bridge connections per radio is 12, with 24 representing the maximum for dual-radio models.

CAUTION An access point is Base Bridge mode logs out whenever a Client ! Bridge associates to the Base Bridge over the LAN connection. This

problem is not experienced over the access point???s WAN connection. If this situation is experienced, log-in to the access point again.

Once the settings within the Radio Configuration screen are applied (for an initial deployment), the current number of client bridge connections for this specific radio displays within the CBs Connected field. If this is an existing radio within a mesh network, this value updates in real-time.

CAUTION A problem could arise if a Base Bridge???s Indoor channel is not

! available on an Outdoor Client Bridge's list of available channels. As long as an Outdoor Client Bridge has the Indoor Base Bridge channel in its available list of channels, it can associate to the Base Bridge.

5.Select the Client Bridge checkbox to enable the access point radio to initiate client bridge connections with other mesh network supported access point???s using the same WLAN.

If the Client Bridge checkbox has been selected, use the Mesh Network Name drop-down menu to select the WLAN (ESS) the client bridge uses to establish a wireless link. The default setting, is (WLAN1). Motorola recommends creating (and naming) a WLAN specifically for mesh networking support to differentiate the Mesh supported WLAN from non-Mesh supported WLANs.

CAUTION An access point in client bridge mode cannot use a WLAN configured ! with a Kerberos or EAP 802.1x based security scheme, as these

authentication types secure user credentials not the mesh network itself.

NOTE Ensure you have verified the radio configuration for both Radio 1 and Radio 2 before saving the existing settings and exiting the Radio Configuration screen.

5-54 AP-51xx Access Point Product Reference Guide

Once the settings within the Radio Configuration screen are applied (for an initial deployment), the current number of base bridges visible to the radio displays within the BBs Visible field, and the number of base bridges currently connected to the radio displays within the BBs Connected field. If this is an existing radio within a mesh network, these values update in real-time.

6.Click the Advanced button to define a prioritized list of access points to define Mesh Connection links. For a detailed overview on mesh networking and how to configure the radio for mesh networking support, see Configuring Mesh Networking Support on page 9-6.

7.If using a dual-radio model access point, refer to the Mesh Timeout drop-down menu to define whether one of the radio???s beacons on an existing WLAN or if a client bridge radio uses an uplink connection. The Mesh Timeout value is not available on a single-radio access point, since the radio would have to stop beaconing and go into scan mode to determine if a base bridge uplink is lost. The following drop-down menu options are available:

Network Management 5-55

For a detailed overview on mesh networking and how to configure the radio for mesh networking support, see Configuring Mesh Networking Support on page 9-6.

8.Click Apply to save any changes to the Radio Configuration screen. Navigating away from the screen without clicking Apply results in all changes to the screens being lost.

CAUTION When defining a Mesh configuration and changes are saved, the ! mesh network temporarily goes down. The Mesh network is

unavailable because the access point radio is reconfigured when applying changes. This can be problematic for users making changes within a deployed mesh network. If updating the mesh network using a LAN connection, the access point applet loses connection and the connection must be re-instated. If updating the mesh network using a WAN connection, the access point applet does not lose connection, but the mesh network is unavailable until the changes have been applied.

9.Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings displayed on the Radio Configuration screen to the last saved configuration.

10.Click Logout to securely exit the Access Point applet. A prompt displays confirming the logout before the applet is closed.

Once the target radio has been enabled from the Radio Configuration screen, configure the radio???s properties by selecting it from the access point menu tree.

For more information, see Configuring the 802.11a or 802.11b/g Radio on page 5-55.

5.3.2.1 Configuring the 802.11a or 802.11b/g Radio

Configure an 802.11a or 802.11b/g radio by selecting the radio???s name (as defined using the 802.11a or 802.11b/g radio configuration screen described below) as a sub-menu item under the Radio Configuration menu item. Use the radio configuration screen to set the radio???s placement properties, define the radio???s threshold and QoS settings, set the radio???s channel and antenna settings and define beacon and DTIM intervals.

To configure the access point???s 802.11a or 802.11b/g radio:

1.Select Network Configuration -> Wireless -> Radio Configuration -> Radio1 (default name) from the access point menu tree.

On a single-radio model, Radio1 could either be an 802.11a or 802.11b/g radio depending on which radio has been enabled.

5-56 AP-51xx Access Point Product Reference Guide

2. Configure the Properties field to assign a name and placement designation for the radio.

Network Management 5-57

3.Configure the Radio Settings field to assign a channel, antenna diversity setting, radio transmit power level and data rate.

5-58 AP-51xx Access Point Product Reference Guide

Network Management 5-59

4. Refer to the Beacon Settings field to set the radio beacon and DTIM intervals.

5-60 AP-51xx Access Point Product Reference Guide

5.Refer to the QBSS Load Element Setting field to optionally allow the access point to communicate channel usage data to associated devices and define the beacon interval used for channel utilization transmissions. The QBSS load represents the percentage of time the channel is in use by the access point and its station count. This information is very helpful in assessing the access point???s overall load on the channel, its availability for additional device associations and multi media traffic support.

Select the Enable QBSS load element checkbox (its selected by default) to enable the access point to communicate channel usage to MUs. Access points with high channel usage may not be able to process real-time traffic effectively. Therefore, VOIP phones can use the QBSS value to determine whether a different access point association can provide better wireless support, since the QBSS network load is reduced as additional access points are added.

If QBSS is enabled, define a QBSS Beacon Interval to define the beacon time (in seconds) the access point uses to broadcast channel utilization information. This information should be periodically accessed, as the access point???s network load will fluctuate throughout the day.

6.Configure the Performance field to set the preamble, thresholds values and QoS values for the radio.
