Overview
The Cisco Aironet 1130AG Series Access Point is available in autonomous and lightweight
configurations. The autonomous access points can support standalone network configurations with all
configuration settings maintained within the access points. The lightweight access points operate in
conjunction with a Cisco wireless LAN controller with all configuration information maintained within
the controller.
Product Terminology
The following terms refer to the autonomous and lightweight products:
•
•
•
•
•
The term access point describes both autonomous and lightweight products.
The term autonomous access point describes only the autonomous product.
The term lightweight access point describs only the lightweight product.
The term access point describes the product when configured to operate as an access point.
The term bridge describes the product when configured to operate as a bridge.
Autonomous Access Points
Cisco Aironet 1130AG Series Access Point (models: AIR-AP1131AG and AIR-AP1131G) supports a
management system based on Cisco IOS software. The 1130AG series access point is a Wi-Fi certified,
wireless LAN transceiver. The 1131AG access point uses dual integrated radios (IEEE 802.11g and
IEEE-802.11a). The 1131G access point uses a single integrated radio (IEEE 802.11g).
The access point serves as the connection point between wireless and wired networks or as the center
point of a stand-alone wireless network. In large installations, wireless users within radio range of an
access point can roam throughout a facility while maintaining uninterrupted access to the network.
You can configure and monitor the access point using the command-line interface (CLI), the
browser-based management system, or Simple Network Management Protocol (SNMP).
Lightweight Access Points
The Cisco Aironet 1130AG Series Access Point (models: AIR-LAP1131AG and AIR-LAP1131G) is
part of the Cisco Integrated Wireless Network Solution and requires no manual configuration before they
are mounted. The lightweight access point is automatically configured by a Cisco wireless LAN
controller (hereafter called a controller) using the Lightweight Access Point Protocol (LWAPP).

Chapter 1 Overview
Guidelines for Using 1130AG Series Lightweight Access Points
The lightweight 1131AG access point contains two integrated radios: a 2.4-GHz radio (IEEE 802.11g)
and a 5-GHz radio (IEEE 801.11a). The lightweight 1131G access point contains one integrated radio:
a 2.4-GHz radio (IEEE 802.11g). Using a controller, you can configure the radio settings.
In the Cisco Centralized Wireless LAN architecture, access points operate in the lightweight mode (as
opposed to autonomous mode). The lightweight access points associate to a controller. The controller
manages the configuration, firmware, and controls transactions such as 802.1x authentication. In
addition, all wireless traffic is tunneled through the controller.
LWAPP is an Internet Engineering Task Force (IETF) draft protocol that defines the control messaging
for setup and path authentication and run-time operations. LWAPP also defines the tunneling mechanism
for data traffic.
In an LWAPP environment, a lightweight access point discovers a controller by using LWAPP discovery
mechanisms and then sends it an LWAPP join request. The controller sends the lightweight access point
an LWAPP join response allowing the access point to join the controller. When the access point is joined,
the access point downloads its software if the versions on the access point and controller do not match.
After an access point joins a controller, you can reassign it to any controller on your network.
LWAPP secures the control communication between the lightweight access point and controller by
means of a secure key distribution, using X.509 certificates on both the access point and controller.
This chapter provides information on the following topics:
•
•
•
Guidelines for Using 1130AG Series Lightweight Access Points
You should keep these guidelines in mind when you use a 1130AG series lightweight access point:
•
•
•
The access points can communicate only with 2006 or 4400 series controllers. Cisco 4100 series,
Airespace 4012 series, and Airespace 4024 series controllers are not supported because they lack
the memory required to support access points running Cisco IOS software.
The access points do not support Wireless Domain Services (WDS). The access points communicate
only with controllers and cannot communicate with WDS devices. However, the controller provides
functionality equivalent to WDS when the access point associates to it.
The access points support eight BSSIDs per radio and a total of eight wireless LANs per access
point. When a lightweight access point associates to a controller, only wireless LANs with IDs 1
through 8 are pushed to the access point.
•
•
The access points do not support Layer 2 LWAPP. They must get an IP address and discover the
controller using DHCP, DNS, or IP subnet broadcast.
The access point console port is enabled for monitoring and debuging purposes (all configuration
commands are disabled after connecting to a controller).

Hardware Features
Single or Dual-Radio Operation
The 1131AG access point supports simultaneous radio operation using a 2.4-GHz 802.11g radio and a
5-GHz 802.11a radio. The 1131G access point supports a single 2.4-GHz 802.11g radio. Each radio uses
dual-diversity integrated antennas.
The 5-GHz radio incorporates an Unlicensed National Information Infrastructure (UNII) radio
transceiver operating in the UNII 5-GHz frequency bands. The 802.11g radio is called Radio0 and the
802.11a radio is called Radio1.
Ethernet Port
The auto-sensing Ethernet port accepts an RJ-45 connector, linking the access point to your 10BASE-T
or 100BASE-T Ethernet LAN. The access point can receive power through the Ethernet cable from a
power injector, switch, or power patch panel. The Ethernet MAC address is printed on the label on the
back of the access point (refer to the “Locating the Product Serial Number” section on page xiii). The
Note
Do not attempt to connect a cable with a protective boot to the access point Ethernet port. Because of
limited space in the connection area, booted connectors might not fit.
Console Port
The serial console port can be used to monitor the access point power-up sequences using a terminal
emulator program. The port is located in a cable bay area that is hidden by the top cover (see Figure 1-1).
Use an RJ-45 to DB-9 serial cable to connect your computer’s COM port to the access point’s serial
pinouts.) Assign the following port settings to a terminal emulator to open the management system
pages: 9600 baud, 8 data bits, No parity, 1 stop bit, and no flow control.
Note
Do not attempt to connect a cable with a protective boot to the access point console port. Because of
limited space in the connection area, booted connectors might not fit.
LEDs
The access point has three LEDs to indicate Ethernet activity, radio activity, and status indications (see
•
•
The Status LED provides general operating status and error indications (top cover closed).
The Ethernet LED is located in the cable bay area under the access point top cover. This LED signals
Ethernet traffic on the wired Ethernet LAN and provides Ethernet error indications.
•
The Radio LED is located in the cable bay area under the access point top cover. This LED signals
that wireless packets are being transmitted or received over the radio interface and provides radio
error indications.
Note
The access point cover must be closed to view the Status LED but the cover must be open to view the
Ethernet and the Radio LEDs.

Power Sources
The access point can receive power from an external power module or from inline power using the
Ethernet cable. The access point supports the IEEE 802.3af inline power standard and Cisco CDP Power
Negotiation. Using inline power, you do not need to run a power cord to the access point because power
is supplied over the Ethernet cable.
Warning
Caution
This product must be connected to a Power over Ethernet (PoE) IEEE 802.3af compliant power source
or an IEC60950 compliant limited power source. Statement 353
Be careful when handling the access point; the bottom plate might be hot.
The access point supports the following power sources:
•
•
Power module
Inline power:

–
Other inline power switches supporting the IEEE 802.3af inline power standard
Note
Some switches and patch panels might not provide enough power to operate the access point when
configured with both 2.4-GHz and 5-GHz radios. At power-up, if the access point is unable to determine
that the power source can supply sufficient power, the access point automatically deactivates both radios
to prevent an over-current condition. The access point also activates a Status LED low power error
UL 2043 Certification
The access point has adequate fire resistance and low smoke-producing characteristics suitable for
operation in a building's environmental air space, such as above suspended ceilings, in accordance with
Section 300-22(c) of the NEC, and with Sections 2-128, 12-010(3) and 12-100 of the Canadian

Network Examples with Autonomous Access Points
This section describes the autonomous access point’s role in three common wireless network
configurations. The autonomous access point’s default configuration is as a root unit connected to a
wired LAN or as the central unit in an all-wireless network. The repeater or workgroup bridge roles
require a specific configurationsetting.
The autonomous 1130AG series access point supports these operating wireless modes:
•
•
Root access point—Connected to a wired LAN and supports wireless clients.
Repeater access point—Not connected to a wired LAN, associates to a root access point, and
supports wireless clients
•
Workgroup bridge—Not connected to a wired LAN, associates to a root access point or bridge, and
supports wired network devices.

Network Examples with Autonomous Access Points
Root Unit on a Wired LAN
An autonomous access point connected directly to a wired LAN provides a connection point for wireless
users. If more than one autonomous access point is connected to the LAN, users can roam from one area
of a facility to another without losing their connection to the network. As users move out of range of one
access point, they automatically connect to the network (associate) through another access point. The
roaming process is seamless and transparent to the user. Figure 1-4 shows access points acting as root
units on a wired LAN.

Network Examples with Autonomous Access Points
Repeater Unit that Extends Wireless Range
An autonomous access point can be configured as a stand-alone repeater to extend the range of your
infrastructure or to overcome an obstacle that blocks radio communication. The repeater forwards traffic
between wireless users and the wired LAN by sending packets to either another repeater or to an access
point connected to the wired LAN. The data is sent through the route that provides the best performance
for the client. Figure 1-5 shows an autonomous access point acting as a repeater. Consult the Cisco IOS
Software Configuration Guide for Cisco Aironet Access Points for instructions on setting up an access
point as a repeater.
Note
Non-Cisco client devices might have difficulty communicating with repeater access points.

Network Example with Lightweight Access Points
In Figure 1-8, the autonomous unit is configured in workgroup bridge mode and is associated to a Cisco
Aironet root bridge as a wireless bridge device. This configuration allows the Ethernet-enabled devices
pass Ethernet traffic to and from the main LAN using the workgroup bridge. The main advantage of this
configuration is that the wireless communication link can be over a longer distance than an access point
supports. Typically, an access point can communicate over approximately a 1-mile range; however, the
bridge-to-bridge wireless link can communicate over approximately a 21-mile range.

Network Example with Lightweight Access Points
The lightweight access points support Layer 3 network operation. Lightweight access points and
controllers in Layer 3 configurations use IP addresses and UDP packets, which can be routed through
large networks. Layer 3 operation is scalable and recommended by Cisco. Figure 1-9 illustrates a typical
network configuration containing lightweight access points.

Chapter 2 Installing the Access Point
Basic Installation Guidelines
Basic Installation Guidelines
Because the access point is a radio device, it is susceptible to interference that can reduce throughput
and range. Follow these basic guidelines to ensure the best possible performance:
•
•
Ensure a site survey has been performed to determine the optimum placement of access points.
For lightweight access points, check the latest release notes to ensure that your controller software
version supports the access points to be installed. You can find the controller release notes by
selecting your controller under Wireless LAN Controllers at this URL:
Ensure that access points are not mounted closer than 20 cm (7.9 in) from the body of all persons
Do not mount the access point within 3 feet of metal obstructions.
•
•
•
.
Install the access point away from microwave ovens. Microwave ovens operate on the same
frequency as the access point and can cause signal interference.
•
•
Do not mount the access point outside of buildings.
Do not mount the access points on walls or other vertical surfaces.
Controller Discovery Process for Lightweight Access Points
The lightweight access point supports these controller discovery processes:
•
•
•
DHCP server discovery—Uses DHCP Option 43 to provide controller IP addresses to the
lightweight access points. Cisco switches support a DHCP server option. For additional information,
DNS server discovery—The lightweight access point uses the name
CISCO-LWAPP-CONTROLLER.<local domain> to discover the controller IP addresses from a
DNS server. Where <local domain> is the access point domain name.
Locally stored controller IP addresses—If the lightweight access point was previously associated to
a controller, the IP addresses of the primary, secondary, and tertiary controllers are stored in the
access point non-volitile memory. The process of storing controller IP addresses in access points for
later deployment is called priming the lightweight access point. For additional information, refer to
You can also manually configure controller information using CLI commands on new
(out-of-the-box) access points that are not connected to a controller. For additional information refer
Cisco recommends that you configure a DHCP server with Option 43 to provide the controller IP
addresses to your lightweight access points. Cisco switches provide a DHCP server option that is
typically used for this purpose.

Deploying the Access Points on the Wireless Network
Deploying the Access Points on the Wireless Network
Prior to beginning the actual access point deployment, perform these tasks:
•
•
•
Ensure that a site survey has been preformed.
Ensure that your network infrastructure devices are operational and properly configured.
For lightweight access points, perform these tasks:
–
–
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.
To deploy your access points, follow these steps:
Step 1
Step 2
Obtain the access point location map created during your building site survey.
Review the access point locations and identify the specific mounting methods required for each access
point location.
Step 3
For each access point perform these steps:
a. For lightweight access points, record the access point MAC address on the access point location
map. When you have completed the access point deployment, return the access point MAC addresses
and the access point locations on the access point location maps or floor plans to your network
planner or manager. The network operators can use the MAC address and location information to
create maps for precise wireless system management.
b. Attach your access point to the mounting plate (see the “Attaching the Access Point to the Mounting
c. Mount the access point at the indicated destination using the specified mounting method. For
specific mounting instructions, see these sections:

Checking Basic Settings
Mismatched basic settings are the most common causes of lost connectivity with wireless clients. If the
access point does not communicate with client devices, check the following areas.
Default IP Address Behavior
When you connect an 1130AG access point running Cisco IOS Release 12.3(2)JA or later software with
a default configuration to your LAN, the access point requests an IP address from your DHCP server,
and if it does not receive an IP address, it continues to send requests indefinitely.
Default SSID and Radio Behavior
In Cisco IOS Relese 12.3(2)JA2 and earlier, the access point radios are enabled by default and the default
SSIDs are tsunami.
In Cisco IOS Release 12.3(4)JA and later, the access point radios are disabled by default, and there are
no default SSIDs. You must create an SSID and enable the radio before the access point will allow
wireless associations from other devices. These changes to the default configuration improve the
security of newly installed access points. Refer to the Cisco IOS Software Configuration Guide for Cisco
section on page 3-5 for instructions on enabling the radio interfaces.

Enable Radio Interfaces
To enable the radio interfaces, follow these instructions:
Step 1
Step 2
Use your web-browser to access your access point.
When the Summary Status page displays, click Network Interfaces > Radio0-802.11B or
Radio0-802.11G and the radio status page displays.
Step 3
Step 4
Step 5
Step 6
Step 7

Click Network Interfaces > Radio0-802.11A and the radio status page displays.
Click Settings and the radio settings page displays.
Click Enable in the Enable Radio field.
Click Apply.
Step 10 Close your web-browser.
SSID
Wireless clients attempting to associate with the access point must use the same SSID as the access point.
If a client device’s SSID does not match the SSID of an access point in radio range, the client device will
not associate. The access point default SSID is tsunami. Refer to the Cisco IOS Software Configuration
Guide for Cisco Aironet Access Points for instructions on how to configure an SSID.
Note
The default SSID (tsunami) is not supported in access points running Cisco IOS Release 12.3(4)JA or
later. You must configure an SSID before client devices can associate to the access point.
WEP Keys
The WEP key you use to transmit data must be set up exactly the same on your access point and any
wireless devices with which it associates. For example, if you set WEP Key 3 on your client adapter to
0987654321 and select it as the transmit key, you must also set WEP Key 3 on the access point to exactly
the same value. The access point does not need to use Key 3 as its transmit key, however.
Refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points for instructions
on setting the access point’s WEP keys.
Security Settings
Wireless clients attempting to authenticate with your access point must support the same security options
configured in the access point, such as EAP or LEAP, MAC address authentication, Message Integrity
Check (MIC), WEP key hashing, and 802.1X protocol versions.

Chapter 3 Troubleshooting Autonomous Access Points
Low Power Condition for Autonomous Access Points
If a wireless client is unable to authenticate with your access point, contact the system administrator for
proper security settings in the client adapter and for the client adapter driver and firmware versions that
are compatible with the access point settings.
Note
The access point MAC address that appears on the Status page in the Aironet Client Utility (ACU) is the
MAC address for the access point radio. The MAC address for the access point Ethernet port is printed
on the label on the back of the access point.
Low Power Condition for Autonomous Access Points
Warning
This product must be connected to a Power over Ethernet (PoE) IEEE 802.3af compliant power source
or an IEC60950 compliant limited power source. Statement 353
The access point can be powered from the 48-VDC power module or from an in-line power source. The
access point supports the IEEE 802.3af power standard, Cisco Pre-Standard PoE protocol, and Cisco
Intelligent Power Management for in-line power sources.
For full operation, the access point requires 12.95 W of power. The power module and Cisco Aironet
power injectors are capable of supplying the required power for full operation, but some inline power
sources are not capable of supplying 12.95 W. Also, some high-power inline power sources, might not
be able to provide 12.95 W of power to all ports at the same time.
Note
Note
An 802.3af compliant switch (Cisco or non-Cisco) is capable of supplying sufficient power for full
operation.
If your access point is connected to in-line power, do not connect the power module to the access point.
Using two power sources on the access point might cause the access point to shut down to protect internal
components and might cause the switch to shut down the port to which the access point is connected. If
your access point shuts down, you must remove all power and reconnect only a single power source.
On power up, the access point is placed into low power mode (both radios are disabled), Cisco IOS
software loads and runs, and power negotiation determines if sufficient power is available. If there is
sufficient power then the radios are turned on; otherwise, the access point remains in low power mode
with the radios disabled to prevent a possible over-current condition. In low power mode, the access
point activates the Status LED low power error indication, displays a low power message on the browser
and serial interfaces, and creates an event log entry (see the “Checking the Autonomous Access Point
Intelligent Power Management
The access point requires 12.95 W of power for full power operation with both radios, but only needs
6.3 W of power when operating in low power mode with both radios disabled. To help avoid an
over-current condition with low power sources and to optimize power usage on Cisco switches, Cisco
developed Intelligent Power Management, which uses Cisco Discovery Protocol (CDP) to allow
powered devices (such as your access point) to negotiate with a Cisco switch for sufficient power.

Chapter 3 Troubleshooting Autonomous Access Points
Low Power Condition for Autonomous Access Points
The access point supports Intelligent Power Management and as a result of the power negotiations, the
access point will either enter full power mode or remain in low power mode with the radios disabled.
Note
Independent of the power negotiations, the access point hardware also uses the 802.3af classification
scheme to indicate the power required from the power source. However, the power source cannot report
the power available to the access point unless the power source also supports Intelligent Power
Management.
Some Cisco switches that are capable of supplying sufficient power require a software upgrade to
support Intelligent Power Management. If the software upgrade is not desired, you can configure the
access point to operate in pre-standard compatibility mode and the access point automatically enters full
power mode if these Cisco switches are detected in the received CDP ID field.
When the access point determines that sufficient power is not available for full power operation, an error
message is logged and the Status LED turns amber to indicate low power mode (see the “Checking the
Tip
If your switch is capable of supplying sufficient power for full operation but the access point remains in
low-power mode, your access point or your switch (or both) might be misconfigured (see Table 3-2 and
If your inline power source is not able to supply sufficient power for full operation, you should consider
these options:
•
•
•
Upgrade to a higher-powered switch
Use a Cisco Aironet power injector on the switch port
Use the 48-VDC power module to locally power the access point
Inline Power Status Messages

Chapter 3 Troubleshooting Autonomous Access Points
Low Power Condition for Autonomous Access Points
Configuring Power Using the CLI
Intelligent Power Management support is dependent on the version of software resident in the Cisco
switch that is providing power to the access point. Each Cisco switch should be upgraded to support
Intelligent Power Management. Until the software is upgraded, you can configure the access point to
operate with older Cisco switch software using the following Cisco IOS CLI command:
[no]power inline negotiation {prestandard source |injector {installed | override | H.H.H}}
(prestandard source indicates the Cisco switch does not support Intelligent Power
Management. injector installed indicates a power injector is installed on the current
switch port. injector override indicates a power injector is installed and the access
point is configured to override the inline power checks. When you move the access point,
H.H.H is used to specify the MAC address of the new switch port where the access point was
moved. A MAC address of 0.0.0 is invalid.)
Caution
Note
When using the power inline negotiation injector override command, a power injector must always be
installed to prevent a possible overload condition with an underpowered power source.
The power inline negotiation injector installed command will fail if CDP is disabled.
When using the p;ower inline negotiation injector override command, you must use a power injector to
prevent possiblly overloading underpowered power sources.
You can use this Cisco IOS CLI command to inform the access point of the following:
•
•
•
The Cisco switch does not support Intelligent Power Management but should be able to supply
sufficient power.
A power injector is being used to supply sufficient power and the Cisco switch does not support
Intelligent Power Management.
The access point was moved to a new Cisco switch port and a power injector is being used to supply
sufficient power.
Caution
Note
If the access point receives power through PoE, the output current of the power sourcing equipment
(PSE) cannot exceed 400 mA per port. The power source must comply with IEEE802.3af or IEC60950
for limited power sources.
After completing your configuration changes, you must remove the serial console cable from the access
point.

Chapter 4 Troubleshooting Lightweight Access Points
Guidelines for Using 1130AG Series Lightweight Access Points
Guidelines for Using 1130AG Series Lightweight Access Points
Keep these guidelines in mind when you use a 1130AG series lightweight access point:
•
The access points can only communicate with Cisco 2006 series or 4400 series controllers.
Note
Cisco 4100 series, Airespace 4012 series, and Airespace 4024 series controllers are not
supported because they lack the memory required to support access points running Cisco
IOS software.
•
•
The access points do 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 points support eight BSSIDs per radio and a total of eight wireless LANs per access
point. When a lightweight access point associates to a controller, only wireless LANs with IDs 1
through 8 are pushed to the access point.
•
•
The access points do not support Layer 2 LWAPP. They must get an IP address and discover the
controller using DHCP, DNS, or IP subnet broadcast.
The access point console port is enabled for monitoring and debug purposes (all configuration
commands are disabled when connected to a controller).
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. For additional informataion, refer to the “Configuring
Checking the Lightweight Access Point LEDs
If your access point is not working properly, check the Status LED on the top panel or the Ethernet and
Radio LEDs in the cable bay area. You can use the LED indications to quickly assess the unit’s status.

Chapter 4 Troubleshooting Lightweight Access Points
Low Power Condition for Lightweight Access Points
Low Power Condition for Lightweight Access Points
Warning
This product must be connected to a Power over Ethernet (PoE) IEEE 802.3af compliant power source
or an IEC60950 compliant limited power source. Statement 353
The lightweight access point can be powered from the 48-VDC power module or from an in-line power
source. The access point supports the IEEE 802.3af power standard, Cisco Pre-Standard PoE protocol,
and Cisco Intelligent Power Management for in-line power sources.
For full operation, the access point requires 12.95 W of power. The power module and Cisco Aironet
power injectors are capable of supplying the required power for full operation, but some inline power
sources are not capable of supplying 12.95 W. Also, some high-power inline power sources, might not
be able to provide 12.95 W of power to all ports at the same time.
Note
Note
An 802.3af compliant switch (Cisco or non-Cisco) is capable of supplying sufficient power for full
operation.
If your access point is connected to in-line power, do not connect the power module to the access point.
Using two power sources on the access point might cause the access point to shut down to protect internal
components and might cause the switch to shut down the port to which the access point is connected. If
your access point shuts down, you must remove all power and reconnect only a single power source.
On power up, the access point is placed into low power mode (both radios are disabled), Cisco IOS
software loads and runs, and power negotiation determines if sufficient power is available. If there is
sufficient power then both radios are turned on; otherwise, the access point remains in low power mode
with one or both radios disabled to prevent a possible over-current condition. In low power mode, the
access point activates the Status LED low power error indication (see the “Checking the Lightweight
Intelligent Power Management
The access point requires 12.95 W of power for full power operation with both radios, but only needs
6.3 W of power when operating in low power mode with both radios disabled. To help avoid an
over-current condition with low power sources and to optimize power usage on Cisco switches, Cisco
developed Intelligent Power Management, which uses Cisco Discovery Protocol (CDP) to allow
powered devices (such as your access point) to negotiate with a Cisco switch for sufficient power.
The access point supports Intelligent Power Management and as a result of the power negotiations, the
access point will either enter full power mode or remain in low power mode with one or both radios
disabled.
Note
Independent of the power negotiations, the access point hardware also uses the 802.3af classification
scheme to indicate the power required from the power source. However, the power source cannot report
the power available to the access point unless the power source also supports Intelligent Power
Management.

Low Power Condition for Lightweight Access Points
Some Cisco switches that are capable of supplying sufficient power require a software upgrade to
support Intelligent Power Management. If the software upgrade is not desired, you can configure the
access point to operate in pre-standard compatibility mode and the access point automatically enters full
power mode if these Cisco switches are detected in the received CDP ID field.
When the access point determines that sufficient power is not available for full-power operation, one or
both readios are deactivated and the Status LED turns amber to indicate low power mode (see Table 4-1).
If your Cisco switch is capable of supplying sufficient power for full operation but the access point
remains in low-power mode, your access point or your switch (or both) might be misconfigured (see
If your inline power source is not able to supply sufficient power for full operation, you should consider
•
•
•
Upgrade to a higher-powered switch
Use a Cisco Aironet power injector on the switch port
Use the 48-VDC power module to locally power the access point
Configuring Power Using Controller CLI Commands
Intelligent Power Management support is dependent on the version of software resident in the Cisco
switch that is providing power to the access point. Each Cisco switch should be upgraded to support
Intelligent Power Management. Until the software is upgraded, you can use your controller to configure
the access point to operate with older switch software using these controller CLI commands:
1) config ap power pre-standard enable <ap>
where <ap> is the access point name on the controller
2) config ap power injector enable <ap> <switch port MAC address>
(where <ap> is the access point name on the controller
and <switch port MAC address> is the MAC address of the switch port to which the
access point is connected)
Note
Refer to your controller documentation for instructions on using these commands.
You can use these controller CLI commands to inform the access point of the following:
•
The Cisco switch does not support Intelligent Power Management but should be able to supply
sufficient power.
•
A power injector is being used to supply sufficient power and the Cisco switch does not support
Intelligent Power Management.
Caution
If the access point receives power through PoE, the output current of the power sourcing equipment
(PSE) cannot exceed 400 mA per port. The power source must comply with IEEE 802.3af or IEC60950
for limited power sources.

2. Power injector must be AIR-PWRINJ3 or AIR-PWRINJ-FIB.
3. Cisco switches that support Intelligent Power Management always configure the use of a power injector at the switch.
Manually Configuring Controller Information Using the Access
Point CLI
In a new installation, when your access point is unable to reach a DHCP server, you can manually
configure needed controller information using the access point CLI. For information on how to connect
Note
The CLI commands in this section can be used only on an access point that is not associated to a
controller.
The static information configured with the CLI commands are used by the access point to connect with
a controller. After connecting with the controller, the controller reconfigures the access point with new
controller settings, but the static IP addresses for the access point and the default gateway are not
changed.

Chapter 4 Troubleshooting Lightweight Access Points
Returning the Access Point to Autonomous Mode
Configuring Controller Information
To manually configure controller information on a new (out-of -the-box) access point using the access
point CLI interface, you can use these EXEC mode CLI commands:
AP# lwapp ap ip address <IP address> <subnet mask>
AP# lwapp ip default-gateway IP-address
AP# lwapp controller ip address IP-address
AP# lwapp ap hostname name
Where name is the access point name on the controller.
Note
The default (out-of-box) Enable password is Cisco.
Clearing Manually Entered Controller Information
When you move your access point to a different location in your network, you must clear the manually
entered controller information to allow your access point to associate with a different controller.
Note
This command requires the controller configured Enable password to enter the CLI EXEC mode.
To clear or remove the manually entered controller information, you can use these EXEC mode CLI
commands:
clear lwapp ap ip address
clear lwapp ip default-gateway
clear lwapp controller ip address
clear lwapp ap hostname
Manually Resetting the Access Point to Defaults
You can manually reset your access point to default settings using this EXEC mode CLI command:
Note
This command requires the controller configured Enable password to enter the CLI EXEC mode.
clear lwapp private-config
Returning the Access Point to Autonomous Mode
You can return a lightweight access point to autonomous mode by loading a Cisco IOS release that
supports autonomous mode (such as Cisco IOS Release 12.3(7)JA or earlier). If the access point is
associated to a controller, you can use the controller to load the Cisco IOS release. If the access point is
not associated to a controller, you can load the Cisco IOS release using TFTP.

Priming Lightweight Access Points Prior to
Deployment
This section describes an optional procedure designed to prime or stage your lightweight access points
in a convenient location rather than after they are installed in possibly difficult to reach locations. This
process can be used when a DHCP server is not reachable by your deployed access point and it helps
limit potential installation problems to primarily Ethernet and power areas.
Figure F-1 illustrates a typical priming configuration for your lightweight access points.

Appendix F Priming Lightweight Access Points Prior to Deployment
Before deploying your lightweight access points to their final locations, follow these steps to prime your
access points:
Step 1
Step 2
In a Layer 2 environment, where the lightweight access points are located on the same subnet as the
controller, the access point communicates directly with the controller.
In a Layer 3 environment, ensure a DHCP server (typically on your switch) is enabled on the same subnet
as your lightweight access points. The access points will receive its IP address and controller information
using DHCP Option 43.
The lightweight access point must be able to find the IP address of the controller. This can be
accomplished using DHCP, DNS, OTAP, or IP subnet broadcast. This guide describes the DHCP method
to convey the controller IP address. For more information, refer to the “Configuring DHCP Option 43
Note
For a Layer 3 access point on a different subnet than the controller, ensure ensure the route to
the controller has destination UDP ports 12222 and 12223 open for LWAPP communications.
Ensure the routes to the primary, secondary, and tertiary controllers allow IP packet fragments.
Step 3
Step 4
Ensure that your controller is connected to a switch trunk port.
Configure the controller in LWAPP Layer 3 mode and ensurethat its DS Port is connected to the switch.
Use the CLI, web-browser interface, or Cisco WCS procedures as described in the appropriate controller
guide.
a. In multi-controller environments, You can set one controller’s DS port to Master (you can use the
config network master-base disable CLI command or you can use the controller GUI) so that new
access points always associate with it. You can use the show network config CLI command to
determine if the controller DS port is the master.
All access points associate to the master controller. From one location, you can configure access
point settings such as primary, secondary, and tertiary controllers. This allows you to redistribute
your access points to other controllers on the network.
You can also use a Cisco WCS server to control, configure, and redistribute all your access points
from a single location.
Step 5
Apply power to the lightweight access points:
a. Connect your lightweight access points to untagged access ports on your POE capable switch. You
can optionally use power modules or power injectors to power your access points.
b. After you power up the lightweight access point, it begins a power-up sequence that you can check
by observing the access point LEDs. All LEDs blink sequentially back and forth, indicating that the
access point is trying to find a controller.
Note
If the lightweight access point remains in this mode for more than 5 minutes, the access point is
unable to find the master controller. Check the connection between the access point and the
controller and ensure they are on the same subnet.
c. If the lightweight access point shuts down (all LEDs off), check to ensure that sufficient power is
available.
d. When the lightweight access point associates with the controller, if the access point code version
differs from the controller code version, the access point downloads the operating system code from
the controller. All the access point LEDs blink simultaneously during the download.

Appendix F Priming Lightweight Access Points Prior to Deployment
Step 6
Step 7
Step 8
Step 9
If the operating system download is successful, the lightweight access point reboots. Normal operation
is indicated when the radio LED is blinking to indicate radio activity.
Use controller CLI, controller GUI, or Cisco WCS to configure the lightweight access point with
primary, secondary, and tertiary controller names.
If the lightweight access point is in a Controller Mobility Group, use the controller CLI, controller GUI,
or Cisco WCS to configure the Controller Mobility Group name.
Use controller CLI, controller GUI, or Cisco WCS to configure the access point-specific 802.11a,
802.11b, and 802.11g network settings.
Step 10 If the configuration priming was successful, the radio LED is blinking to indicate normal operation.
Step 11 Repeat Steps 4 to 9 for each access point.
When you successfully complete the configuration priming of all your lightweight access points, ensure
Master setting is disabled on your controller. You can begin deploying the access points to their final
destinations.

Appendix G Configuring DHCP Option 43 for Lightweight Access Points
Overview
Overview
This section contains a DHCP Option 43 configuration example on a Windows 2003 Enterprise DHCP
server for use with Cisco Aironet lightweight access points. For other DHCP server implementations,
consult the DHCP server documentation for configuring DHCP Option 43. In Option 43, you should 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 and 1500 series 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’s DHCP Vendor Class
Identifier (VCI) string (DHCP Option 60). The VCI strings for Cisco access points capable of operating

<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”
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:

P
A basic message unit for communication across a network. A packet usually includes routing
packet
information, data, and sometimes error detection information.
Q
QPSK
Quadruple phase shift keying is a modulation technique used by IEEE
802.11b-compliant wireless LANs for transmission at 2 Mbps.
R
A linear measure of the distance that a transmitter can send a signal.
range
A measurement of the weakest signal a receiver can receive and still correctly
translate it into data.
receiver sensitivity
Radio frequency. A generic term for radio-based technology.
RF
A feature of some Access Points that allows users to move through a facility
while maintaining an unbroken connection to the LAN.
roaming
A connector type unique to Cisco Aironet radios and antennas. Part 15.203 of
the FCC rules covering spread spectrum devices limits the types of antennas that
may be used with transmission equipment. In compliance with this rule, Cisco
Aironet, like all other wireless LAN providers, equips its radios and antennas
with a unique connector to prevent attachment of non-approved antennas to
radios.
RP-TNC
S
A radio transmission technology that spreads the user information over a much
wider bandwidth than otherwise required in order to gain benefits such as
improved interference tolerance and unlicensed operation.
spread spectrum
Service set identifier (also referred to as Radio Network Name). A unique
identifier used to identify a radio network and which stations must use to be able
to communicate with each other or to an access point. The SSID can be any
alphanumeric entry up to a maximum of 32 characters.
SSID
T
The power level of radio transmission.

W
Wireless Domain Services. An access point providing WDS on your wireless
LAN maintains a cache of credentials for CCKM-capable client devices on your
wireless LAN. When a CCKM-capable client roams from one access point to
another, the WDS access point forwards the client's credentials to the new access
point with the multicast key. Only two packets pass between the client and the
new access point, greatly shortening the reassociation time.
WDS
Wired Equivalent Privacy. An optional security mechanism defined within the
802.11 standard designed to make the link integrity of wireless devices equal to
that of a cable.
WEP
Wireless LAN Solutions Engine. The WLSE is a specialized appliance for
managing Cisco Aironet wireless LAN infrastructures. It centrally identifies and
configures access points in customer-defined groups and reports on throughput
and client associations. WLSE's centralized management capabilities are further
enhanced with an integrated template-based configuration tool for added
configuration ease and improved productivity.
WLSE
Wireless Network Manager.
WNM
A computing device with an installed client adapter.

WPA
Wi-Fi Protected Access is a standards-based, interoperable security enhancement
that strongly increases the level of data protection and access control for existing
and future wireless LAN systems. It is derived from and will be
forward-compatible with the upcoming IEEE 802.11i standard. WPA leverages
TKIP (Temporal Key Integrity Protocol) for data protection and 802.1X for
authenticated key management.
