C H A P T E R

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.

Antenna Configurations

The 1552 access point supports a variety of antennas designed for outdoor use with radios operating in

the 2.4-GHz and 5-GHz frequency bands. In addition to an integrated antenna array, the 1552 supports

the external antennas listed in the following sections.

Two mounting configurations are available, the cable strand mount and the pole mount (refer to

“Mounting the Access Point” section on page 2-14.)

Using an optional antenna mounting bracket kit, the directional antennas AIR-ANT2413P2M-N and

AIR-ANT5114P2M-N can be mounted directly on an access point in a strand mount or pole mount

environment. The antenna bracket kit contains four bracket sections and fasteners that you can assemble

in multiple configurations to position and aim the directional antenna in a range of positions. For more

information on mounting the antenna with the optional mounting bracket, refer to Installing

Directional-Antenna Mounting Kits on Cisco 1550 Series Outdoor Mesh Access Points.

The AIR-CAP1552E-x-K9 model must always be operated with the three external antennas attached.

Figure 1-10 shows the antenna port locations for model 1552E.

Low Profile Dual-Band 2.4/5-GHz Omni Antenna Array

The Low Profile Dual-Band 2.4/5 GHz Omni Antenna Array has the following basic features:

•

Contains an array of three dual-band omni antennas—The three omni antennas are contained within

this single radome, which greatly reduces the antenna’s visual footprint and reduces the possibility

of snagging the antenna on the cable bundle, the RF cable, or test cables.

•

Operates over both 2.4 GHz and 5 GHz bands—Each of the three omni antennas is a dual-band

antenna, covering both the 2.4–2.5 GHz band, and the 5.2–5.9 GHz bands.

•

Gain of about 2 dBi at 2.4 GHz, 4 dBi at 5 GHz.

Cisco Light Gray weatherproof radome for outdoor operation.

Chapter 1 Overview

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

(2.4 GHz and 5 GHz)

(5 GHz)

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.

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)

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 1 Overview

Network Deployment Examples

Point-to-Multipoint Mesh Network

The access point is typically deployed in a mesh network configuration. In a typical mesh deployment,

one or more RAPs have a wired network connection through a switch to a controller. Other remote MAPs

without wired network connections use the backhaul feature to optimally link to a RAP that is connected

to the wired network. In the mesh network, the links between the access points are referred to as the

backhaul links.

Intelligent wireless routing is provided by the Adaptive Wireless Path protocol (AWPP). This enables

each MAP to identify its neighbors and intelligently choose the optimal path to the RAP with the wired

network connection by calculating the cost of each path in terms of signal strength and the number of

hops required to get to a controller with signal strength given priority since signal strength determines

the data rate available for backhaul.

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.

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:

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/).

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

series of standards. To meet CAN/CSA-C22.2 No. 60950-22-07/UL60950-22 requirements, the installer

may use alternative components to provide this additional protection. Those components may comply

with ANSI/IEEE C62.11, CSA Certification Notice No. 516, CSA C22.2 No. 1, or UL 1449. Suitability

of the components for the application must be determined for the intended installation. (For example,

some devices are suitable for installation on the load side of the service entrance only, and some are

suitable for use with cord-connected equipment only.)

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).

Chapter 2 Installing the Access Point

Grounding the Access Point

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

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.

Step 2

Step 3

Choose SECURITY > MAC Filtering > New.

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

Step 5

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

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

Step 7

Step 8

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

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

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

Step 2

Log into your controller using a web browser.

Click Wireless. When your access point associates to the controller, the name of the access point appears

in the AP Name list.

Step 3

Step 4

Step 5

Step 6

Step 7

Double-click your access point name.

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

Click Apply.

Repeat Steps 2 through 5 for each RAP.

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

Chapter 2 Installing the Access Point

What to Do Next

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

Log into your controller using a web browser.

Step 1

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

Step 4

Step 5

Step 6

Step 7

Double-click on an access point name.

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

Click Apply.

Repeat Steps 2 through 5 for each access point.

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.

Chapter 3 Troubleshooting

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.

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.

Note

The access point MAC address and barcode is located on the bottom of the unit. When two MAC

addresses are shown, use the top MAC address.

To view the MAC addresses added to the controller MAC filter list, you can use the controller CLI or the

controller GUI:

•

Controller CLI—Use the show macfilter summary controller CLI command to view the MAC

addresses added to the controller filter list.

•

Controller GUI—Log into your controller web interface using a web browser, and choose

SECURITY > AAA > MAC Filtering to view the MAC addresses added to the controller filter list.

Chapter 3 Troubleshooting

Using DHCP Option 43

You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling

the access point to find and join a controller. Refer to the product documentation for your DHCP server

for instructions on configuring DHCP Option 43. For additional information, refer to the “Configuring

DHCP Option 43” section on page F-1.

Monitoring the Access Point LEDs

If your access point is not working properly, look at the LEDs on the bottom of the unit. You can use

them to quickly assess the status of the unit. Figure 3-1 shows the location of the access point LEDs.

Chapter 3 Troubleshooting

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

Step 2

Log into your controller using a web browser.

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

Name list.

Step 3

Step 4

Step 5

Step 6

Step 7

Click on an access point name.

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

Click Apply.

Repeat Steps 2 through 5 for each access point.

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

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.

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

Step 2

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

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

Step 4

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.

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:

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

Step 2

Enter configuration mode at the Cisco IOS CLI.

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

Step 4

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.

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
