Overview
The Cisco Aironet 1570 Series Outdoor Access Point (hereafter called the access point or AP) is a
wireless outdoor access point which is designed for use in a variety of network configurations. The
access point supports wireless client access, point-to-point bridging, point-to-multipoint bridging, and
point-to-multipoint mesh wireless connectivity.
About the Access Point
The Cisco Aironet 1570 Series Outdoor Access Point (hereafter called the access point or AP) is a high
performance outdoor access point designed for service in outdoor and mesh networks.
All versions of the access point have simultaneous dual-band radio consisting of an 802.11ac Wave 1
4x4:3 5 GHz radio and 4x4:3 802.11n 2.4 GHz radio. The access point versions which have a cable
modem, support up to 16x8 channel bonding.
The 1570 series access points have both internal and external antenna versions.
The internal antenna versions (AIR-AP1572IC versions) are optimized for service provider applications
using cable modem or fiber for data backhaul, rely on power-over-cable as the primary power source,
and provide GPS capability as an option.
The external antenna versions (AIR-AP1572E versions) have four dual band capable external antennas
ports. These versions support power over Ethernet input (AIR-AP1572EAC version only), power over
Ethernet output supporting up to 802.3at devices, internal AC or power over cable power supply options.
The access point can be 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 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. The access point can also be deployed
in an autonomous mode and be configured via the CLI.

Warning
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023
Caution
Power injectors must be used indoors only. Do not place a power injector in an unprotected outdoor
environment because water could get into the power injector and cause a short circuit and possible fire.
Caution
When the access point is installed outdoors or in a wet or damp location, the AC branch circuit that is
powering the access point should be provided with ground fault protection (GFCI), as required by Article
210 of the National Electrical Code (NEC).
Depending on the version of the access point, you may have the following power options available in
your access point:
•
Power-over-cable (PoC) - The only source for internal antenna versions (AIR-AP1572I versions)
•
AC
•
DC
•
UPOE (or AIR-PWRINJ1500-2 power injector)
The external antenna versions (AIR-AP1572E versions) support power over Ethernet input (on the AC
version only), power over Ethernet output supporting up to 802.3at devices, internal AC or power over
cable power supply options.
If multiple power sources are available, the access point will select the power source which is higher
on the following prioritization list. If a power source is removed, access point will automatically switch
to the next available power source, as per this list:
1.
Power-over-cable or AC (whichever is available on your AP)
2.
External DC input
3.
PoE (available in AC powered versions of AP)
Power-over-Cable
All versions of AIR-AP1572I and some versions of AIR-AP1572E are equipped with a
power-over-cable (PoC) power supply. The power supply can accept quasi-AC signals in the 40 to 90
V RMS range.
Versions of the AP that have a PoC power supply, also have a shunt/fuse interface providing direct
in-line access to the PoC AC signal. The AP comes with a shunt in the shunt/fuse location. By removing
the shunt or fuse, field technicians can immediately remove power to the AP for service and repairs,
and then restore power by re-installing the shunt or fuse. You can install a fuse in the shunt/fuse
location to limit the maximum sustained current supplied to the AP to prevent damage to the AP or to
the cable plant. Fuses of various amperage are available, and so you can select the appropriate fuse
rating depending on the configuration and operating voltage.

The access point also supports an Ethernet uplink port (PoE-In). The access point Ethernet uplink port
uses an RJ-45 connector (with weatherproofing) to link the access point to the 10BASE-T, 100BASE-T
or 1000BASE-T network. The Ethernet cable is used to send and receive Ethernet data and to
optionally supply inline power from the power injector or a suitably powered switch port.
Tip
The access point senses the Ethernet and power signals and automatically switches internal circuitry to
match the cable connections.
The Ethernet cable must be a shielded outdoor rated Category 5e (CAT5e) or better cable. The access

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 (hereafter called a RAP) or a mesh
(non-root) access point (hereafter called a MAP), which is the default role of all access points. When the
access point has a fiber or wired Ethernet 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 connection to the controller (through a switch),
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 which has an Ethernet connection through a switch to the controller.
MAPs may 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 1-1). 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.

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 1-2. 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.

The access points can also support point-to-point bridging under autonomous mode. In this autonomous
mode, the bridging can be done on the 2.4 or 5 GHz radio, but not both. In this mode, one access point
is designated as the root and the other end is designated as the non-root bridge.

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 1-4 illustrates an example
of access point-to-multipoint bridging.

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.
Figure 1-6 illustrates a typical mesh configuration using MAPs and RAPs.

not to come into contact with such circuits, because they may cause serious injury or death. For
proper installation and grounding of the antenna, please refer to national and local codes (for
example, U.S.:NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code,
Section 54). Statement 1052
Caution
Before connecting or disconnecting a power cord, you must remove power from the power cord using a
suitable service disconnect.
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.

Avoiding Damage to Radios in a Testing Environment
•
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:
•
Note
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.
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.
For a radiated test bed, the following equation describes the relationships among transmit power, antenna
gain, attenuation, and receiver sensitivity:
txpwr +
Where:
txpwr =
tx gain
rx gain
tx gain + rx gain - [attenuation due to antenna spacing] < max rx input level
Radio transmit power level
= transmitter antenna 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:

•
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.
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.
Site surveys reveals problems that can be resolved before the network is operational. Because
802.11a/b/g/n operates in an unlicensed spectrum, there may be sources of interference from other
802.11a wireless devices (especially in multi-tenant buildings) that could degrade your 802.11 signals.
A site survey can determine if such interference exists at the time of deployment.
A proper site survey involves temporarily setting up mesh links and taking measurements to determine
whether your antenna calculations are accurate. Determine the correct locations and antenna types
before you drill holes and route cables and mounting equipment.
Consider the following operating and environmental conditions when performing a site survey:
•
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.
•
How far is your wireless link?
•
Has a previous site survey been conducted?
•
Do you have a clear Fresnel zone between the access points or radio line of sight?
•
What is the minimum acceptable data rate within the link?
•
Do you have the correct antenna (if more than one antenna is being offered?)
•
Do you have access to both of the mesh site locations?

One PMK is designed specifically for the 1570I series and another PMK is designed specifically for the
1570E series.
The 1570I PMK allows the AP to be mounted in a horizontal orientation with antennas downward when
attached to a horizontal pole, vertical pole, or wall. The 1570E PMK allows the AP to be mounted
vertically when attached to a horizontal pole, vertical pole, or wall. Arbitrary off angle poles are not
supported. Both PMKs can be mounted to poles in diameter from 2 to 16 inches. Both PMKs maintain
a low profile with approximately 1 inch clearance between the pole/wall and the AP.
Pedestal Mount Kits
The 1570I series AP has a pedestal mount kit that allows it to be installed into a Channell 1420 pedestal
housing. The 1570E has a pedestal mount allowing it to be installed into a Channell 1212 pedestal
housing.
Access Point Mounting Orientation
When mounting an access point on a horizontal or vertical surface, you must ensure that the access
point is oriented with the LED indicators pointing down. This positioning allows LEDs to be visible
to someone on the ground below the access point.
You must also ensure the access point is mounted in such a way as to ensure that all antenna ports and
the console port are accessible for future use.
Note
Omnidirectional antennas are vertically polarized and should be mounted vertically.

Installing Antennas
Non-Cisco Antennas
Cisco does not support any third-party antennas. RF connectivity and compliance of third party antennas
is the customer’s responsibility. Cisco does not recommend any third-party antennas, and Cisco
Technical Assistance Center will not be able to provide any support for third-party antennas. Cisco’s
FCC Part 15 compliance is only guaranteed with Cisco antennas or antennas that are of the same design
and gain as Cisco antennas.
Safety Precautions when Installing Antennas
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
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.
Antenna Configurations
Integrated Antenna Option
The AP1572I uses an Integrated Low Profile Dual-Band 2.4-5 GHz Dipole Antenna Array. The antenna
contains an array of three dual-band dipole antennas. The three dipole antennas are contained within this
single radome, thereby greatly reducing the antenna’s visual footprint, and greatly reducing the
possibility of snagging the antenna on the cable bundle, the RF cable, or test cables. Each of thee three

Installing a Lightning Arrestor
Overvoltage transients can be created through lightning static discharges, switch processes, direct
contact with power lines, or through earth currents. The Cisco Aironet AIR-ACC245LA-N Lightning
Arrestor limits the amplitude and duration of disturbing interference voltages and improves the over
voltage resistance of in-line equipment, systems, and components. A lightning arrestor installed
according to these mounting instructions balances the voltage potential, thus preventing inductive
interference to parallel signal lines within the protected system.

Chapter 2
Installing the Access Point
Installing Antennas
Installation Considerations
Cisco recommends that you bulkhead mount the lightning arrestor so it can be installed as a wall-feed
through on the wall of the protected space.
The importance of obtaining a good ground and bonding connection cannot be overstressed. Consider
these points when grounding the lightning arrestor:
•
Connect the lightning arrestor components directly to the grounding point.
•
The contact points of the ground connection must be clean and free of dust and moisture.
•
Tighten threaded contacts to the torque specified by the manufacturer.
Installation Notes
This lightning arrestor is designed to be installed between the antenna cable that is attached to an outdoor
antenna and the Cisco Aironet wireless device. You can install the lightning arrestor either indoors or
outdoors. It can be connected directly to a wireless device having an external N connector. It can also be
mounted inline or as a feed-through. Feed-through installations require 5/8 in. (16 mm) hole to
accommodate the lightning arrestor.
Note
This lightning arrestor is part of a lightning arrestor kit. The kit contains a lightning arrestor and a
grounding lug.
Note
When you install the lightning arrestor, follow the regulations or best practices applicable to lightning
protection installation in your local area.
Installing the Lightning Arrestor Outdoors
If you install the lightning arrestor outdoors, use the supplied ground lug and a heavy wire (#6 solid
copper) to connect it to a good earth ground, such as a ground rod. The connection should be as short as
possible.

Cable for the Lightning Arrestor
Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. The cable should be
kept as short as possible because cable length also determines the amount of signal loss (the longer the
run, the greater the loss).
Cisco recommends a high-quality, low-loss cable for use with the lightning arrestor.
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
In all outdoor installations and when powering the access point with AC power, you must follow these
instructions to properly ground the case:
Step 1
If using insulated 6-AWG copper ground wire, strip the insulation as required for the grounding lug.

Statement 1001
The 1572 access point supports these power sources:
•
DC power – 24- 57 VDC
•
Power-over-Ethernet (PoE)
The 1572 access point can be powered via the PoE input from an in-line power injector or a suitably
powered switch port. Depending on the configuration and regulatory domain, the required power for full
operation is UPoE. For the 1572E, 802.3at power is sufficient for all regulatory domains and full 2x2
MIMO operation on both 2.4 and 5 GHz radios. Either the AIR-PWRINJ4= or the AIR-PWRINJ1500-2=
power injector can be used.
For the 1572I, UPoE powered switch port or the AIR-PWRINJ1500-2= power injector is required for
full operation of the 3x3 MIMO on the 2.4 GHz radio in the regulatory domains that allow for high 2.4
GHz transmit power (Regulatory domains -A, -D, -F, -K, -N, -Q, -T, -Z). If the 1572I is powered by a
PoE+ (802.3at power) switch port or the AIR-PWRINJ4= power injector, then the access point will
automatically disable one of the 2.4 GHz transmitters and the radio will operate in 2x3 MIMO mode.

What to Do Next
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 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.
•
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). If the wired ports are operational, the RAP can potentially spend several
minutes on each port prior to connecting to a controller.
•
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.

Chapter 3
Troubleshooting
Controller MAC Filter List
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.
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
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.
Note
It is expected that there will be small variations in LED color intensity and hue from unit to unit. This is
within the normal range of the LED manufacturer specifications and is not a defect.
The access point LED signals are listed in Table 3-1.

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.

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, 1532 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.

Configuring Option 43 for 1000, 1500, and 1570 Series Access Points
Configuring Option 43 for 1000, 1500, and 1570 Series Access
Points
To configure DHCP Option 43 for Cisco 1000, 1500, and 1570 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 1570 Series Access Points
To configure DHCP Option 43 for Cisco Aironet 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1570
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 AP1570
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:
