C H A P T E R 1

Overview

The Cisco Aironet 1550 Series Outdoor Mesh Access Point (hereafter called the access point or AP) is a modularized wireless outdoor access point designed for use in a mesh network. The access point also supports wireless client access, point-to-point bridging, point-to-multipoint bridging, and point-to-multipoint mesh wireless connectivity.

About the 1552 Access Point

The 1552 access point supports two radios (2.4-GHz and 5-GHz) and provides client access without the need for a license. The 5-GHz radios are primarily used for backhaul operations to reach a wired network and the 2.4-GHz radio is used for wireless clients. Depending on the radio, the access point can support 1 to 300 Mb/s data rates (for specific data rates, refer to Appendix D, ???Access Point Specifications???).

The 1552 access point supports the modularity of the 1520 series and allows flexibility in radio configuration. In addition to full interoperability with 802.11n clients, the 1552 access point interoperates with legacy clients and offers enhanced backhaul performance. The 1552 access point can also be configured with an integrated DOCSIS 3.0/Euro DOCSIS 3.0 cable modem.

The access point is a standalone unit that can be cable strand or tower mounted. The access point can also operate as a relay node for other access points not directly connected to a wired network. Intelligent wireless routing is provided by the patented Adaptive Wireless Path Protocol (AWPP). This enables each access point to identify its neighbors and intelligently choose the optimal path to the wired network by calculating the cost of each path in terms of signal strength and the number of hops required to get to a controller.

The access point is configured, monitored, and operated through a Cisco wireless LAN controller (hereafter called a controller) as described in the Cisco Wireless LAN Controller Configuration Guide. The Cisco Wireless Mesh Access Points, Design and Deployment Guide, Release 7.3 describes how to plan and initially configure the Cisco mesh network, which supports wireless point-to-point, point-to-multipoint, and mesh deployments. The controllers use a browser-based management system, a command-line interface (CLI), or the Cisco Prime Infrastructure (PI) network management system to manage the controller and the associated access points. The access point supports hardware-based advanced encryption standard (AES) encryption between wireless nodes to provide end-to-end security.

Chapter 1 Overview

Hardware Features

Note When a 1552E or 1552EU access point is powered by PoE, the PoE-Out port is not active.

The access point PoE-out (10/100/1000BASE-T) port uses an RJ-45 connector to provide LAN connectivity and IEEE 802.3af power to a single peripheral customer device, such as a camera or sensor gateway. The PoE-out port should not be connected to a switch or hub. The Ethernet MAC addresses are printed on the bottom of the access point under the LEDs.

Note The PoE-out port is disabled when the access point is powered by the power injector.

Tip The access point senses the Ethernet and power signals and automatically switches internal circuitry to match the cable connections.

Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023

The Ethernet cable must be a shielded outdoor rated Category 5e (CAT5e) or better cable. The access point senses the Ethernet and power signals and automatically switches internal circuitry to match the cable connections.

Caution To provide inline PoE, you must use the 1500 power injector (AIR-PWRINJ1500-2=). Other power injectors, PoE switches, and 802.3af power sources cannot provide adequate power, which may cause the access point to malfunction and cause possible over-current conditions at the power source.

Fiber Option

Warning Class 1 laser product. Statement 1008

The factory-orderable fiber option provides a fiber input and output capability. Fiber data is transmitted and received over a single-strand fiber cable, which is connected to the access point using these SFP modules:

Chapter 1 Overview

Network Deployment Examples

Network Deployment Examples

The access point is a wireless device designed for wireless client access and point-to-point bridging, point-to-multipoint bridging, and point-to-multipoint mesh wireless connectivity. The access point provides 5-GHz backhaul capability to link with another access point to reach a wired network connection or to provide repeater operations for other access points.

The access point plays two primary radio roles: a root access point (RAP) or a mesh (non-root) access point (MAP), which is the default role of all access points. When the access point has a fiber or wired Ethernet or cable connector connection to the controller (through a switch), the radio role is called a RAP. In order to be considered a RAP, the access point must be configured as a RAP. A RAP is a parent node to any bridging or mesh network. A controller can support one or more RAPs, each one parenting the same or different wireless networks. There can be more than one RAP for the same mesh network for redundancy. RAPs and MAPs can support wireless clients on the 2.4-GHz and 5-GHz band. Client access on 5-GHz is called universal client access.

When the access point does not have a wired Ethernet, fiber-optic, or cable connection to the controller, the radio role is called a MAP. The MAPs have a wireless connection (through the backhaul interface) to other MAPs and finally to a RAP with an Ethernet or cable connection through a switch to the controller. MAPs can also have a wired Ethernet connection to a local LAN and serve as a bridge endpoint for that LAN (using a point-to-point or point-to-multipoint bridge connection).

Wireless Backhaul

The access point supports wireless backhaul capability using the 5 GHz radio to bridge to another access point to reach a wired network connection to a controller (see Figure 1-22). The access point connected to the wired network is considered a RAP in this configuration. The remote access point is considered a MAP and transfers wireless client traffic to the RAP for transfer to the wired network. Control And Provisioning of Wireless Access Points (CAPWAP) control traffic is also transferred over this bridged link.

Figure 1-22 Access Point Backhaul Example

255493

Point-to-Point Bridging

The access points can be used to extend a remote network by using the 5 GHz backhaul radio to bridge the two network segments as shown in Figure 1-23. To support Ethernet bridging, you must enable bridging on the controller for each access point. By default this capability is turned-off for all access points.

Chapter 1 Overview

Network Deployment Examples

Wireless client access is supported; however, if bridging between tall buildings, the 2.4-GHz wireless coverage area may be limited and possibly not suitable for direct wireless client access.

Figure 1-23 Access Point Point-to-Point Bridging Example

(5 GHz)

255495

Point-to-Multipoint Bridging

The access points can be used as a RAP to connect multiple remote MAPs with their associated wired networks. By default this capability is turned-off for all access points. To support Ethernet bridging, you must enable bridging on the controller for each access point. Wireless client access can be provided over the bridging link; however, if bridging between tall buildings, the 2.4-GHz wireless coverage area may be limited and possibly not suitable for direct wireless client access. Figure 1-24 illustrates an example of access point-to-multipoint bridging.

Chapter 2 Installing the Access Point

Avoiding Damage to Radios in a Testing Environment

Caution Before connecting or disconnecting a power cord, you must remove AC power from the power cord using a suitable service disconnect.

For additional important safety instructions for AC power cords, refer to the AC Power Cords for Cisco Aironet 1550 Series Outdoor Mesh Access Points document that shipped with your AC power cords.

For safety and to achieve a good installation, please read and follow these safety precautions:

???Select your installation site with safety, as well as performance in mind. Remember: electric power lines and phone lines look alike. For safety, assume that any overhead line can kill.

???Call your electric power company. Tell them your plans, and ask them to come look at your proposed installation.

???Plan your installation carefully and completely before you begin. Successful raising of a mast or tower is largely a matter of coordination. Each person should be assigned to a specific task and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watch for signs of trouble.

???When installing the access point and antennas, remember:

???Do not use a metal ladder.

???Do not work on a wet or windy day.

???Do dress properly???shoes with rubber soles and heels, rubber gloves, long sleeved shirt or jacket.

???Use a rope to lift the access point. If the assembly starts to drop, get away from it and let it fall.

???If any part of the antenna system should come in contact with a power line, do not touch it or try to remove it yourself. Call your local power company. They will remove it safely.

If an accident should occur, call for qualified emergency help immediately.

Avoiding Damage to Radios in a Testing Environment

The radios on outdoor units (bridges) have higher transmit power levels than radios on indoor units (access points). When you test high-power radios in a link, you must avoid exceeding the maximum receive input level for the receiver. At levels above the normal operating range, packet error rate (PER) performance is degraded. At even higher levels, the receiver can be permanently damaged. To avoid receiver damage and PER degradation, you can use one of the following techniques:

???Separate the omnidirectional antennas by at least 2 ft (0.6 m) to avoid receiver damage or by at least 25 ft (7.6 m) to avoid PER degradation.

Note These distances assume free space path loss and are conservative estimates. Required separation distances for damage and performance degradation levels in actual deployments are less if conditions are not non-line-of-sight.

???Reduce the configured transmit power to the minimum level.

???Use directional antennas, and keep them away from each other.

???Cable the radios together using a combination of attenuators, combiners, or splitters to achieve a total attenuation of at least 60 dB.

Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide

Chapter 2 Installing the Access Point

Installation Guidelines

For a radiated test bed, the following equation describes the relationships among transmit power, antenna gain, attenuation, and receiver sensitivity:

txpwr + tx gain + rx gain - [attenuation due to antenna spacing] < max rx input level Where:

txpwr = Radio transmit power level tx gain = transmitter antenna gain rx gain = receiver antenna gain

For a conducted test bed, the following equation describes the relationships among transmit power, antenna gain, and receiver sensitivity:

txpwr - [attenuation due to coaxial components] < max rx input level

Caution Under no circumstances should you connect the antenna port from one access point to the antenna port of another access point without using an RF attenuator. If you connect antenna ports, you must not exceed the maximum survivable receive level of 0 dBm. Never exceed 0 dBm, or damage to the access point can occur. Using attenuators, combiners, and splitters having a total of at least 60 dB of attenuation ensures that the receiver is not damaged and that PER performance is not degraded.

Installation Guidelines

Because the access point is a radio device, it is susceptible to common causes of interference that can reduce throughput and range. Follow these basic guidelines to ensure the best possible performance:

???For information on planning and initially configuring your Cisco Mesh network, refer to the Cisco Wireless Mesh Access Points, Design and Deployment Guide, Release 7.3.

???Review the FCC guidelines for installing and operating outdoor wireless LAN devices at http://www.cisco.com/en/US/partner/prod/collateral/routers/ps272/data_sheet_c78-647116_ps114 51_Products_Data_Sheet.html.

???Perform a site survey before beginning the installation.

???Install the access point in an area where structures, trees, or hills do not obstruct radio signals to and from the access point.

???The access points can be installed at any height, but best throughput is achieved when all the access points are mounted at the same height. We recommend installing the access points no higher than 40 feet to allow support for wireless clients on the ground.

Note To calculate path loss and to determine how far apart to install access points, consult an RF planning expert.

Site Surveys

Every network application is a unique installation. Before installing multiple access points, you should perform a site survey to determine the optimum use of networking components and to maximize range, coverage, and network performance.

Consider the following operating and environmental conditions when performing a site survey:

Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide

Chapter 2 Installing the Access Point

Installation Guidelines

???Data rates???Sensitivity and range are inversely proportional to data bit rates. The maximum radio range is achieved at the lowest workable data rate. A decrease in receiver sensitivity occurs as the radio data increases.

???Antenna type and placement???Proper antenna configuration is a critical factor in maximizing radio range. As a general rule, range increases in proportion to antenna height. However, do not place the antenna higher than necessary, because the extra height also increases potential interference from other unlicensed radio systems and decreases the wireless coverage from the ground.

???Physical environment???Clear or open areas provide better radio range than closed or filled areas.

???Obstructions???Physical obstructions such as buildings, trees, or hills can hinder performance of wireless devices. Avoid locating the devices in a location where there is an obstruction between the sending and receiving antennas.

Before Beginning the Installation

Before you begin the installation process:

???Ensure that a site survey has been performed.

???Ensure that your network infrastructure devices are operational and properly configured.

???Ensure that your controllers are connected to switch trunk ports.

???Ensure that your switch is configured with untagged access ports for connecting your access points.

???Ensure that a DHCP server with Option 43 configured is reachable by your access points, or manually configure the controller information in the access point (for additional information, refer to the ???Configuring DHCP Option 43??? section on page F-1).

???Become familiar with the access point installation components (see the ???Becoming Familiar with Access Point Installation Components??? section on page 2-9).

Becoming Familiar with Access Point Installation Components

The access point is designed to be installed in an outdoor environment, such as the exterior roof overhang of a tall building or a streetlight pole. Carefully review the following figures to become familiar with the system components, connectors, indicators, cables, system interconnection, and grounding:

???Components in a typical access point installation (see Figure 2-1)

???Pole mount installation (see Figure 2-2)

???Cable strand mount installation (see Figure 2-3)

???Streetlight power tap installation (see Figure 2-4)

Note The illustrations in this document show all available connections for the access point. Unused connections are capped with a connector plug to ensure the watertight integrity of the access point, except for the AC power entry connector on the 1552E access point. Liquid-tight adapters are provided for connector openings, which can be installed before or after deploying the access point.

When not using the AC input connector to power the 1552E (for example when powering using the Cisco power injector), it is important to cover the AC power entry connector. The correct cap is Remke part number 75-0086 (http://www.remke.com/).

3.The shielded Ethernet cable has a ground path through the power injector and the safety ground wire in the AC power cord.

Note The 1552 access point was designed with consideration for resistance to effects of lightning effects on the access point electronics. The 1552 access point employs lightning arrestor circuitry on the Ethernet and power ports. On the input Ethernet port, Gas Discharge Tubes (GDT) are used for the Power Entry Module (PEM) to mitigate lightning effect. On the AC power, GDTs are also used along with fuses to mitigate high-current condition. For the DC power, a fuse is used to mitigate high current condition.

While not a common practice, the user may want to consider using lightning protection at the antenna ports for added protection. To meet EN/IEC60950-22 (Clause 4.2) requirements, the installer must ensure that additional protection is provided external to this equipment to reduce transient surges from Overvoltage IV to Overvoltage Category II at the AC power input of the access point. The over-voltage and fault-current protection components used to achieve this protection must comply with the IEC 61643

Installing the Mounting Bracket on a Pole (All Models)

When installing an access point on a vertical pole, mast, or a streetlight pole, you should use the optional Cisco pole mount kit. The kit supports metal, wood, or fiberglass poles from 2 to 16 inches in diameter.

Assembling the Pole Clamp Bracket and the Mounting Bracket

When installing an access point on a pole, mast, or a streetlight, you should use the optional Cisco pole mount kit. The kit supports metal, wood, or fiberglass poles from 2 to 16 inches in diameter.

The pole mount kit contains several parts that you must assemble prior to mounting on a pole. First you need to assemble two strap brackets on the pole clamp bracket that are positioned for the pole diameter you are using to mount the access point. Figure 2-8 illustrates the pole diameter indicators and bolt holes on the pole clamp bracket.

Figure 2-8 Pole Clamp Bracket Adjustment Hole Locations

To assemble the pole clamp bracket, follow these steps:

Chapter 2 Installing the Access Point

Mounting the Access Point

Step 1 Position the strap brackets on the pole clamp bracket for the pole diameter you are using and secure each strap bracket with two M8 x16 bolts (with lock washers) (see Figure 2-9). Tighten the bolts to 13 to 15 ft lbs (17.6 to 20.3 Nm).

Figure 2-9 Assembled Pole Clamp Bracket and Strap Brackets

Step 2 Screw the M8 nut onto the pole clamp bracket support bolt, and tighten just enough to prevent the bolt from falling off.

Step 3 Go to the ???Mounting Bracket Assembly on a Pole??? section on page 2-20.

Chapter 2 Installing the Access Point

Mounting the Access Point

Mounting Bracket Assembly on a Pole

The access point can be installed where power is available, without the need for a wired LAN connection. The access point uses intelligent wireless routing that is based on the Adaptive Wireless Path Protocol (AWPP). AWPP enables a remote access point to dynamically optimize the best route to the wired LAN network using another access point.

The 1552 access point uses the 5-GHz radio for the Mesh backhaul and connections. The 2.4-GHz radio is used for local wireless client access.

To mount your access point on a vertical pole or streetlight pole, you need to install two metal bands around the pole to support the access point. This process requires extra tools and material not provided in the pole mount kit (see Table 2-2).

To mount the access point onto a vertical pole or streetlight pole, follow these steps:

Step 1 Select a mounting location on the pole to mount the access point. You can attach the access point to any pole from 2 to 16 inch (5.1 to 40.6 cm) in diameter.

Note If you will be using a streetlight power tap adapter, position the access point within 3 ft (1 m) of the outdoor light control.

Step 2 For poles larger than 3.5 inch (8.9 cm), mount the pole clamp bracket assembly to a pole (see Figure 2-10) using two metal straps. Following the instructions provided with the banding strap tool

(BAND IT) (AIR-BAND-INST-TL=), loop each metal strap twice through the slots on the strap bracket.

Caution Do not place the metal straps in the large open area between the pole clamp bracket and the strap brackets, because this does not properly secure the access point.

Chapter 2 Installing the Access Point

Mounting the Access Point

Figure 2-10 Clamp Bracket Assembly Mounted on Poles Larger than 3.5 inch (8.9 cm)

Step 3 For pole diameters of 3.5 inch (8.9 cm) or less, mount the pole clamp bracket assembly to a pole using two metal straps looped through the space between the pole clamp bracket and the strap brackets (see Figure 2-11) to provide maximum holding strength for extreme environments. Following the instructions provided with the banding strap tool (BAND IT) (AIR-BAND-INST-TL=), loop each metal strap twice.

Safety Precautions

Warning Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits, as they may cause serious injury or death. For proper installation and grounding of the antenna, please refer to national and local codes (e.g. U.S.: NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54). Statement 280

For your safety, read and follow these safety precautions.

1.Before you install an antenna, contact your Cisco account representative to explain which mounting method to use for the size and type of antenna that you are about to install.

2.Select your installation site with safety, as well as performance, in mind. Remember that electric power lines and phone lines look alike. For your safety, assume that any overhead line can kill you.

3.Contact your electric power company. Tell them your plans and ask them to come look at your proposed installation.

4.Plan your installation carefully and completely before you begin. Each person involved in an installation should be assigned to a specific task and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watch for signs of trouble.

5.When installing your antenna, follow these guidelines:

???Do not use a metal ladder.

???Do not work on a wet or windy day.

???Do dress properly???wear shoes with rubber soles and heels, rubber gloves, and a long-sleeved shirt or jacket.

6.If the assembly starts to drop, move away from it and let it fall. Because the antenna, mast, cable, and metal guy wires are all excellent conductors of electrical current, even the slightest touch of any of these parts to a power line completes an electrical path through the antenna and the installer.

7.If any part of the antenna system should come in contact with a power line, do not touch it or try to remove it yourself. Call your local power company to have it removed safely.

8.If an accident should occur with the power lines, call for qualified emergency help immediately.

Grounding the Access Point

The access point must be grounded before connecting power.

Warning This equipment must be externally grounded using a customer-supplied ground wire before power is applied. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 366

Warning Installation of the equipment must comply with local and national electrical codes. Statement 1074

Chapter 2 Installing the Access Point

The power injector provides (AIR-PWRINJ1500-2=) 56 VDC to the access point over the Ethernet cable and supports a total end-to-end Ethernet cable length of 100 m (328 ft) from the switch to the access point.

Note The PoE-Out port is disabled when the access point is powered by the power injector.

Note When not using the AC input connector to power the 1552E or 1552EU (for example when powering using the Cisco power injector), it is important to cover the AC power entry connector. The correct cap is Remke part number 75-0086 (http://www.remke.com/).

When your access point is powered by an optional power injector, follow these steps to complete the installation:

Step 1 Before applying PoE to the access point, ensure that the access point is grounded (see the ???Grounding the Access Point??? section on page 2-41.

Step 2 Review Figure 2-2 to identify the components needed for the installation.

Note The 1550 power injector can only be used in an indoor environment, therefore, the cable from the injector must travel from the protected location to the outside mounted access point.

Chapter 2 Installing the Access Point

Powering the Access Point

Step 3 Connect a CAT5e or better Ethernet cable from your wired LAN network to the power injector.

Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023

Use only the 1500 power injector (AIR-PWRINJ1500-2=) for the access point. This power injector is designed to meet the power requirements of the access point and is a listed Class 2 limited power source (LPS).

Note The installer is responsible for ensuring that powering the access point from this type of power injector is allowed by local and/or national safety and telecommunications equipment standards.

Tip To forward bridge traffic, add a switch between the power injector and controller. Refer to the

Cisco Wireless Mesh Access Points, Design and Deployment Guide, Release 7.0 for more information.

Step 4 Ensure that the antennas are connected and that a ground is attached to the access point before you apply power to the access point.

Step 5 Connect a shielded outdoor-rated Ethernet (CAT5e or better) cable between the power injector and the PoE-in connector of the access point (see Figure 2-34).

Step 6 Connect the Ethernet cable to the access point PoE-In port (see ???Connecting an Ethernet Cable to the Access Point??? section on page 2-46).

Step 16 Replace the ATTN and SHUNT connector plugs on the top of the access point and tighten to 6 to 7 ft lbs (8.1 to 9.5 Nm).

Configuring the Access Point

Adding the Access Point MAC Addresses to the Controller Filter List

Before installing your access points, configure your controller by adding the MAC addresses of the access points to the filter list. MAC address filtering is enabled by default. This enables the controller to respond to the listed access points. To add a MAC filter entry on the controller, follow these steps:

Step 1 Log into your controller using a web browser.

Chapter 2 Installing the Access Point

Configuring the Access Point

Step 2 Choose SECURITY > MAC Filtering > New.

Step 3 Enter the MAC address of the access point to the MAC Filter list; for example, 00:0B:91:21:3A:C7.

Note The access point MAC address is located on the bottom of the unit. When two MAC addresses are shown, use the top MAC address.

Step 4 Select a WLAN ID or Any WLAN from the WLAN ID pop-up menu.

Step 5 Enter a description (32 characters maximum) of the access point in the Description field; for example, Fisher_Street_00.0B.91.21.3A.C7 shows the location and MAC address of the access point.

Step 6 Choose an interface from the Interface Name pop-up menu, and click Apply.

Step 7 Repeat Steps 2 to 6 to add other access points to the list.

Step 8 Log out of your controller, and close your web browser.

Configuring a RAP

The access point defaults to the mesh access point (MAP) radio role. One or more of your access points must be reconfigured as a root access point (RAP). The RAPs connect to a wired Ethernet link through a switch to the controller. The MAPs use their wireless backhaul interface to connect to a RAP to reach the controller.

To configure a RAP on the controller GUI, follow these steps:

Step 1 Log into your controller using a web browser.

Step 2 Click Wireless. When your access point associates to the controller, the name of the access point appears in the AP Name list.

Step 3 Double-click your access point name.

Step 4 Find Mesh Information, and choose Root AP by clicking the drop-down arrow in the AP Role field.

Step 5 Click Apply.

Step 6 Repeat Steps 2 through 5 for each RAP.

Step 7 Log out from your controller, and close your web browser.

Configuring a Bridge Group Name

The bridge group name (BGN) controls the association of the access points to a RAP. BGNs can be used to logically group the radios to avoid different networks on the same channel from communicating with each other. This setting is also useful if you have more than one RAP in your network in the same area.

If you have two RAPs in your network in the same area (for more capacity), we recommend that you configure the two RAPs with the same BGN, but on different channels.

Chapter 2 Installing the Access Point

Configuring the Access Point

The BGN is a string of ten characters maximum. A factory-set bridge group name (NULL VALUE) is assigned during manufacturing. It is not visible to you, but allows new access point radios to join a network of new access points. The BGN can be reconfigured from the Controller CLI and GUI. After configuring the BGN, the access point reboots.

The BGN should be configured very carefully on a live network. You should always start from the farthest node (last node) from the RAP and move towards the RAP. If you start configuring the BGN in a different location, then the access points beyond this point (farther away) are dropped, as they have a different BGN.

Chapter 2 Installing the Access Point

What to Do Next

To configure the BGN for the access points using the GUI, follow these steps:

Step 1 Log into your controller using a web browser.

Step 2 Click Wireless. When access points associates to the controller, the name of the access point appears in the AP Name list.

Step 3 Double-click on an access point name.

Step 4 Find Mesh Information, and enter the new BGN in the Bridge Group Name field.

Step 5 Click Apply.

Step 6 Repeat Steps 2 through 5 for each access point.

Step 7 Log out from your controller, and close your web browser.

What to Do Next

When you power up a MAP that is not connected to a wired Ethernet, fiber-optic, or cable network to the controller, the access point uses the Cisco Adaptive Wireless Path Protocol (AWPP) to bind to another mesh access point (MAP) with the best path to a root access point (RAP) connected to the wired network to a controller. The access point sends a discovery request when powered up. If you have configured the access point in the controller correctly, the controller sends back a discovery response to the access point. When that happens, the access point sends out a join request to the controller, and the controller responds with a join confirmation response. Then the access point establishes a Control And Provisioning of Wireless Access Points (CAPWAP) connection to the controller and gets the shared secret configured on the controller.

Refer to the Cisco Wireless LAN Controller Configuration Guide for more information on configuring, monitoring, and operating your access points.

Guidelines for Using the Access Points

Guidelines for Using the Access Points

You should keep these guidelines in mind when you use the access points:

???The access point can only communicate with controllers and cannot operate independently.

???The access point does not support Wireless Domain Services (WDS) and cannot communicate with WDS devices. However, the controller provides functionality equivalent to WDS when the access point associates to it.

???The access point only supports Layer 3 CAPWAP communications with the controllers.

In Layer 3 operation, the access point and the controller can be on the same or different subnets. The access point communicates with the controller using standard IP packets. A Layer 3 access point on a different subnet than the controller requires a DHCP server on the access point subnet and a route to the controller. The route to the controller must have destination UDP ports 12222 and 12223 open for CAPWAP communications. The route to the primary, secondary, and tertiary controllers must allow IP packet fragments.

???Before deploying your access points, ensure that the following has been done:

???Your controllers are connected to switch ports that are configured as trunk ports.

???Your access points are connected to switch ports that are configured as untagged access ports.

???A DHCP server is reachable by your access points and has been configured with Option 43. Option 43 provides the IP addresses of the management interfaces of your controllers. Typically, a DHCP server can be configured on a Cisco switch.

???Optionally, a DNS server can be configured to enable CISCO-CAPWAP-CONTROLLER. Use local domain to resolve to the IP address of the management interface of your controller.

???Your controllers are configured and reachable by the access points.

???Your controllers are configured with the access point MAC addresses and the MAC filter list is enabled.

???Your switch must forward DHCP requests.

???The access point PoE-out port should be connected only to a single peripheral customer device, such as a camera or sensor gateway. We recommend that the PoE-out port not be connected to a switch or hub.

???After the access points are associated to the controller, you should change the bridge group name (BGN) from the default value. With the default BGN, the mesh access points (MAPs) can potentially try to connect with other mesh networks and slow down the convergence of the network.

Important Notes

Convergence Delays

During deployment, the access points can experience convergence delays due to various causes. The following list identifies some operating conditions that can cause convergence delays:

???A root access point (RAP) attempts to connect to a controller using any of the wired ports (cable, fiber-optic, PoE-in, or PoE-out). If the wired ports are operational, the RAP can potentially spend several minutes on each port prior to connecting to a controller.

Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide

Chapter 3 Troubleshooting

Controller MAC Filter List

???If a RAP is unable to connect to a controller over the wired ports, it attempts to connect using the wireless network. This results in additional delays when multiple potential wireless paths are available.

???If a MAP is unable to connect to a RAP using a wireless connection, it then attempts to connect using any available wired port. The access point can potentially spend several minutes for each connection method, before attempting the wireless network again.

Bridge Loop

The access point supports packet bridging between wired and wireless network connections. The same network must never be connected to multiple wired ports on an access point or on two bridged access points. A bridge loop causes network routing problems.

Controller DHCP Server

The controller DHCP server only assigns IP addresses to lightweight access points and wireless clients associated to an access point. It does not assign an IP address to other devices, including Ethernet bridging clients on the mesh access points.

MAP Data Traffic

If the signal on the access point backhaul channel has a high signal-to-noise ratio, it is possible for a MAP to connect to the controller, via parent node, but not be able to pass data traffic, such as pinging the access point. This can occur because the default data rate for backhaul control packets is set to 6 Mb/s, and the backhaul data rate set to auto by the user.

Controller MAC Filter List

Before activating your access point, you must ensure that the access point MAC address has been added to the controller MAC filter list and that Mac Filter List is enabled.

Chapter 3 Troubleshooting

Changing the Bridge Group Name

Changing the Bridge Group Name

The bridge group name (BGN) controls the association of the access points to a RAP. BGNs can be used to logically group the radios to avoid different networks on the same channel from communicating with each other. This setting is also useful if you have more than one RAP in your network in the same area.

If you have two RAPs in your network in the same area (for more capacity), we recommend that you configure the two RAPs with different BGNs and on different channels.

The BGN is a string of ten characters maximum. A factory-set bridge group name (NULL VALUE) is assigned during manufacturing. It is not visible to you, but allows new access point radios to join a network of new access points. The BGN can be reconfigured from the Controller CLI and GUI. After configuring the BGN, the access point reboots.

After the access points are deployed and associated to the controller, the BGN should be changed from the default value to prevent the MAPs from attempting to associate to other mesh networks.

The BGN should be configured very carefully on a live network. You should always start with the most distant access point (last node) from the RAP and move towards the RAP. If you start configuring the BGN in a different location, then the access points beyond this point (farther away) are dropped, as they have a different BGN.

To configure the BGN for the access points using the controller GUI, follow these steps:

Step 1 Log into your controller using a web browser.

Step 2 Click Wireless. When access points associates to the controller, the access point name appears in the AP Name list.

Step 3 Click on an access point name.

Step 4 Find the Mesh Information section, and enter the new BGN in the Bridge Group Name field.

Step 5 Click Apply.

Step 6 Repeat Steps 2 through 5 for each access point.

Step 7 Log out from your controller, and close your web browser.

Connecting to the Access Point Locally

If you need to monitor the access point locally (without connecting the access point to a wired LAN), you can connect a PC to its console port using a DB-9 to RJ-45 serial cable.

Note The console port should only be used for debugging in a lab environment.

Follow these steps to open the CLI by connecting to the access point console port:

Step 1 Open the hinged cover of the access point (see ???Opening the Access Point Hinged Cover??? section on page 2-13 for instructions).

Connect a nine-pin, female DB-9 to RJ-45 serial cable to the RJ-45 console port on the access point and to the COM port on a computer (see Figure 3-2 and Figure 3-3 for the console port locations).

Appendix F Configuring DHCP Option 43

Overview

Overview

This section contains a DHCP Option 43 configuration example on a DHCP server for use with Cisco Aironet Access Points. For other DHCP server implementations, consult DHCP server product documentation for configuring DHCP Option 43. In Option 43, use the IP address of the controller management interface.

Note DHCP Option 43 is limited to one access point type per DHCP pool. You must configure a separate DHCP pool for each access point type.

Cisco Aironet 1000, 1500, and 1552 access points use a comma-separated string format for DHCP Option 43. Other Cisco Aironet access points use the type-length-value (TLV) format for DHCP Option 43. DHCP servers must be programmed to return the option based on the access point DHCP Vendor Class Identifier (VCI) string (DHCP Option 60). The VCI strings for Cisco access points that can operate in lightweight mode are listed in Table F-1.

1.For controller release 4.1 or later.

2.For controller release 4.0, the VCI depends on the model.

3.For controller release 3.2.

The following is the format of the TLV block for 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1552 access points:

???Type: 0xf1 (decimal 241)

???Length: Number of controller IP addresses * 4

???Value: List of WLC management interfaces

Configuring Option 43 for 1000, 1500, and 1550 Series Access Points

Configuring Option 43 for 1000, 1500, and 1550 Series Access Points

To configure DHCP Option 43 for Cisco 1000, 1500, and 1550 series access points in the embedded Cisco IOS DHCP server, follow these steps:

Step 1 Enter configuration mode at the Cisco IOS command line interface (CLI).

Step 2 Create the DHCP pool, including the necessary parameters such as default router and name server. These commands are used to create a DHCP pool:

ip dhcp pool pool name network IP Network Netmask default-router Default router dns-server DNS Server

Where:

pool name is the name of the DHCP pool, such as AP1000

IP Network is the network IP address where the controller resides, such as 10.0.15.1 Netmask is the subnet mask, such as 255.255.255.0

Default router is the IP address of the default router, such as 10.0.0.1 DNS Server is the IP address of the DNS server, such as 10.0.10.2

Step 3 Add the Option 60 line for access point using the following syntax:

option 60 ascii ???VCI string???

For the VCI string, use the value from Table F-1. The quotation marks must be included.

Step 4 Add the Option 43 line using the following syntax:

option 43 ascii ???Comma Separated IP Address List???

For example, if you are configuring Option 43 for Cisco 1000, 1500, or 1500 series access points using the controller IP addresses 10.126.126.2 and 10.127.127.2, add the following line to the DHCP pool in the Cisco IOS CLI:

option 43 ascii ???10.126.126.2,10.127.127.2???

The quotation marks must be included.

Configuring Option 43 for 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1550 Series Access Points

Configuring Option 43 for 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1550 Series Access Points

To configure DHCP Option 43 for Cisco Aironet 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1550 series access points in the embedded Cisco IOS DHCP server, follow these steps:

Step 1 Enter configuration mode at the Cisco IOS CLI.

Step 2 Create the DHCP pool, including the necessary parameters such as default router and name server. The commands used to create a DHCP pool are as follows:

ip dhcp pool pool name network IP Network Netmask default-router Default router dns-server DNS Server

Where:

pool name is the name of the DHCP pool, such as AP1550

IP Network is the network IP address where the controller resides, such as 10.0.15.1 Netmask is the subnet mask, such as 255.255.255.0

Default router is the IP address of the default router, such as 10.0.0.1 DNS Server is the IP address of the DNS server, such as 10.0.10.2

Step 3 Add the Option 60 line using the following syntax:

option 60 ascii ???VCI string???

For the VCI string, use the value from Table F-1. The quotation marks must be included.

Step 4 Add the Option 43 line using the following syntax:

option 43 hex hex string

The hex string is assembled by concatenating the TLV values shown below:

Type + Length + Value

Type is always f1(hex). Length is the number of controller management IP addresses times 4 in hex. Value is the IP address of the controller listed sequentially in hex.

For example, suppose that there are two controllers with management interface IP addresses, 10.126.126.2 and 10.127.127.2. The type is f1(hex). The length is 2 * 4 = 8 = 08 (hex). The IP addresses translate to 0a7e7e02 and 0a7f7f02. Assembling the string then yields f1080a7e7e020a7f7f02. The resulting Cisco IOS command added to the DHCP scope is listed below:

option 43 hex f1080a7e7e020a7f7f02
