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 a product operating as an access point.

• The term bridge describes a product operating as a bridge.

Autonomous Access Points

Cisco Aironet 1200 Series Access Points (models: AIR-AP1200, AIR-AP1210, AIR-AP1220B,
AIR-AP1230B, AIR-AP1220A, AIR-AP-1230A, AIR-AP1231G, and AIR-AP1232AG) provide a
secure, affordable, and easy-to-use wireless LAN solution that combines mobility and flexibility with
the enterprise-class features required by networking professionals. With a management system based on
Cisco IOS software, the 1200 series access point is a Wi-Fi certified, wireless LAN transceiver.

The 1200 series access point can contain two radios: a 2.4-GHz radio (IEEE 802.11b or IEEE 802.11g)

n an internal mini-PCI slot and a 5-GHz radio module (IEEE 802.11a) in an external, modified cardbus

i
slot. The access point supports one radio of each type, but it does not support two 2.4-GHz or two 5-GHz
radios. You can configure the radios separately, using different settings on each radio.

The access point serves as the connection point between wireless and wired networks or as the center

nt of a stand-alone wireless network. In large installations, wireless users within radio range of an

poi
access point can roam throughout a facility while maintaining seamless, uninterrupted access to the
network.

You can configure and monitor the access point using the command-line interface (CLI), the

owser-based management system, or Simple Network Management Protocol (SNMP).

Lightweight Access Points

The Cisco Aironet 1200 Series Access Points (modes: AIR-LAP1231G and AIR-LAP1232AG) combine
mobility and flexibility with the enterprise-class features required by networking professionals. These
access points are part of the Cisco Integrated Wireless Network Solution and require no manual
configuration before they are mounted. The access point is automatically configured by a Cisco wireless
LAN controller (hereafter called a controller) using the Lightweight Access Point Protocol (LWAPP).

The access point contains two integrated radios: a 2.4-GHz radio (IEEE 802.11g) and a 5-GHz radio

EEE 802.11a). Using a controller, you can configure the radios separately with different settings on

(I
each.

Note The 1200 series lightweight does not support the 802.11b radio or the 802.11a RM20A radio module.

In the Cisco Centralized Wireless LAN architecture, access points operate in the lightweight mode (as
opp

osed to autonomous mode). The access points associate to a controller. The controller manages the
configuration, firmware, and control 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

r setup and path authentication and run-time operations. LWAPP also defines the tunneling mechanism

fo
for data traffic.

In an LWAPP environment, a lightweight access point discovers a controller by using LWAPP discovery
m

echanisms and then sends it an LWAPP join request. The controller sends the access point an LWAPP
join response allowing the access point to join the controller. When the access point is joined, the access
point attempts to download new operating system software if the software 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 access point and controller by means of a secure

ey distribution, utilizing X.509 certificates on both the access point and controller.

Chapter 1 Overview

Guidelines for Using 1200 Series Lightweight Access Points

Guidelines for Using 1200 Series Lightweight Access Points

You should keep these guidelines in mind when you use a 1200 series lightweight access point:

• The access points can only communicate with Cisco 2006 series wireless LAN controllers 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) 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).

Hardware Features

This section describes access point features. Refer to Appendix C, “Access Point Specifications,” for a
list of access point specifications.

Key hardware features of the 1200 series access point include:

• Dual-Radio Operation, page 1-4

• LEDs, page 1-5

• Ethernet Port, page 1-5

• Console Port, page 1-6

• Power Sources, page 1-6

• UL 2043 Certification, page 1-6

Hardware Features

Dual-Radio Operation

The access point can be initially configured at the factory for single- or dual-radio operation. You can
also upgrade an access point configured for single-radio operation to support dual-radio operation using
a 5-GHz radio module or a 2.4-GHz mini-PCI radio card. The access point supports one radio of each
type, but it does not support two 2.4-GHz or two 5-GHz radios.

The 1200 series access point supports these radios:

• 2.4-GHz IEEE 802.11b mini-PCI radio card: MP20B, hereafter called 802.11b radio.

• 2.4-GHz 802.11g mini-PCI radio cards: MP21G or MP31G, hereafter called the 802.11g radio.

• 5-GHz 802.11a radio modules:

AIR-RM22A-x-K9—802.11a radio module with external RP-TNC antenna connectors,
hereafter called the RM22A radio module.

Note The autonomous access points require Cisco IOS Release 12.3(2)JA or later.

Note Cisco Aironet CB20A client radios can sometimes fail to associate to the RM21A or RM22A radio

modules because the CB20A client radio does not support all the channels supported by the radio
modules. The default channel setting for the RM21A or RM22A radio module, least congested, often
results in the access point settling on one of these frequencies that the CB20A client radio does not
support: channel 149 (5745 GHz), channel 153 (5765 GHz), channel 157 (5785 GHz), and channel 161
(5805 GHz). To avoid this problem, set the channel on the RM21A or RM22A radio module to one of
the channels supported by the CB20A client radio. For additional information, refer to the Cisco IOS

Software Configuration Guide for Cisco Aironet Access Points or the Cisco IOS Software Configuration
Guide for Cisco Aironet Access Points.

Hardware Features

All 5-GHz radio modules incorporate an Unlicensed National Information Infrastructure (UNII) radio
transceiver operating in the UNII 5-GHz frequency bands. The RM21A radio modules contains dual
integrated omnidirectional antennas and directional antennas for diversity operation. For autonomous
access points, the 802.11g radio is called Radio0 and the 802.11a radio is called Radio1.

The three LEDs on the top of the access point report Ethernet activity, association status, and radio
activity.

• The Ethernet LED signals Ethernet traffic on the wired LAN, or Ethernet infrastructure. This LED

is normally green when an Ethernet cable is connected and blinks green when a packet is received
or transmitted over the Ethernet infrastructure. The LED is off when the Ethernet cable is not
connected.

• The status LED signals operational status. Green indicates that the access point is associated with

at least one wireless client. Blinking green indicates that the access point is operating normally but
is not associated with any wireless devices.

• The radio LED signals wireless traffic over the radio interface. The light is normally off, but it blinks

green whenever a packet is received or transmitted over the access point radio.

Root Access Point 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 1-2 shows access points acting as root
units on a wired LAN.

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 1-3 shows an autonomous access point acting as a repeater. Consult the Ci

Chapter 2 Installing the Access Point

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 that 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:

http://www.cisco.com/en/US/products/hw/wireless/tsd_products_support_category_home.html

• Ensure that access points are not mounted closer than 20 cm (7.9 in) from

• Do not mount the access point within 3 ft (91.4 cm) 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 building perimeter walls unless outside coverage is desired.

Basic Installation Guidelines

the body of all persons

.

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 access

points. Cisco switches support a DHCP server option. For additional information, refer to the

“Configuring DHCP Option 43 for Lightweight Access Points” section on page G-1.

• DNS server discovery—The 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 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 access point. For additional information, refer to the “Priming

Lightweight Access Points Prior to Deployment” section on page F-1.

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

(
to the “Manually Configuring Controller Information Using the Access Point CLI” section on

page 7-5.

Cisco recommends that you configure a DHCP server with Option 43 to provide the controller IP

dresses to your access points. Cisco switches provide a DHCP server option that is typically used for

ad
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 Obtain the access point location map created during your building site survey.

Step 2 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 lightweight 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. Mount the access point at the indicated destination using the specified mounting method. For

specific mounting instructions, see these sections:

–

Attaching the access point to the mounting plate (see the “Attaching the Access Point to the

Mounting Bracket” section on page 3-8).

–

Horizontal or vertical surface, such as a ceiling or wall (see the “Mounting on a Horizontal or

Vertical Surface” section on page 3-3).

–

Below a suspended ceiling (see the “Mounting Below a Suspended Ceiling” section on

page 3-4).

–

Above a suspended ceiling (see the “Mounting Above a Suspended Ceiling” section on

page 3-5).

c. Optionally secure the access point using a padlock or security cable (see the “Securing the Access

Point to the Mounting Bracket” section on page 3-8).

d. Connect the access point cables (Ethernet, optional power, optional antennas). For instructions see

the “Connecting the Ethernet and Power Cables” section on page 2-9.

e. On power up, verify that the access point is associated to a controller and operating normally. For

additional information, refer to the “Checking the Top Panel LEDs” section on page 6-2.

The product compliance label always occupies the top space (location 1). The two spaces below the
product compliance label (locations 2 and 3) contain the radio compliance labels. Whether or not
locations 2 or 3 contain labels depends on how your access point is configured. For example, the access
point could have two radio compliance labels (one for each radio device installed), or the access point
could have only a product compliance label, depending on how it was ordered.

Make sure that your access point has the correct labels after you install or upgrade its radio configuration

hat it will be in compliance with regulations in your country.

Checking the Top Panel LEDs

If your access point is not communicating, check the three LEDs on the top panel. You can use them to
quickly assess the unit’s status. Figure 6-1 shows the LEDs.

Figure 6-1 Access Point LEDs

Chapter 6 Troubleshooting Autonomous Access Points

The LEDs signals have the following meanings (for additional details refer to Table 6-1):

• The Ethernet LED signals traffic on the wired LAN, or Ethernet infrastructure. This LED is

normally green when an Ethernet cable is connected, and blinks green when a packet is received or
transmitted over the Ethernet infrastructure. The LED is off when the Ethernet cable is not
connected.

• The status LED signals operational status. Steady green indicates that the access point is associated

with at least one wireless client. Blinking green indicates that the access point is operating normally
but is not associated with any wireless devices.

• The radio LED blinks green to indicate radio traffic activity. The light is normally off, but it blinks

green whenever a packet is received or transmitted over the access point’s radio.

Checking Basic Settings

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 a 1200 series 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, continues to send requests indefinitely.

When you connect a 1200 series access point running Cisco IOS Release 12.2(15)JA or earlier 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, the access point assigns a default IP address of 10.0.0.1

Default SSID and Radio Behavior

Chapter 6 Troubleshooting Autonomous Access Points

In Cisco IOS Release 12.3(2)JA and earlier, the access point radio is enabled by default and the default
SSID is tsunami.

In Cisco IOS Release 12.3(4)JAand later, the access point radio is disabled by default for security
reasons, and there is no default SSID. 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 Aironet Access Points for instructions on configuring the SSID and the “Enabling the

Radio Interfaces” section on page 6-4 for instructions on enabling the radio interface.

Enabling the Radio Interfaces

In Cisco IOS Release 12.3(4)JA and later, the access point radios are disabled by default, and there is no
default SSID. You must create an SSID and enable the radios 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 Aironet
Access Points for instructions on configuring the SSID.

To enable the radio interfaces, follow these instructions:

Step 1 Use your internet browser to access your access point.

Step 2 At the prompt, enter the administrator username and password. The default username is Cisco and the

default password is Cisco. The username and password are case sensitive.

Step 3 When the Summary Status page displays, click Network Interfaces > Radio0-802.11b or Network

Interfaces > Radio0-802.11g and the radio status page displays.

6-4

Step 4 Click Settings and the radio settings page displays.

Step 5 Click Enable in the Enable Radio field and click Apply.

Step 6 Click Radio1-802.11A and the radio status page displays.

Step 7 Repeat Steps 3 and 4.

Cisco Aironet 1200 Series Access Point Hardware Installation Guide

OL-8370-04

Chapter 6 Troubleshooting Autonomous Access Points

Step 8 Close your internet 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. In Cisco IOS Release 12.3(2)JA2 and earlier, the access point default SSID is tsunami.

Note In Cisco IOS Release 12.3(4)JA and later, there is no default SSID. 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.

Running the Carrier Busy Test

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.

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.

Running the Carrier Busy Test

You can use the carrier busy test to find the least congested channel for a radio interface (802.11b/g or

802.11a). You should typically run the test several times to obtain the best results and to avoid temporary
activity spikes.

OL-8370-04

Cisco Aironet 1200 Series Access Point Hardware Installation Guide

6-5

Running the Ping or Link Test

Note The carrier busy test is primarily used for a single access point or a bridge environment. For sites with

multiple access points, a site survey is typically performed to determine the best operating locations and
operating frequencies for the access points.

Note All associated clients on the selected radio will be disassociated during the 6 to 8 seconds needed for the

carrier busy test.

Perform these steps to activate the carrier busy test:

Step 1 Use your web browser to open the access point interface.

Chapter 7 Troubleshooting Lightweight Access Points

Guidelines for Using 1200 Series Lightweight Access Points

Guidelines for Using 1200 Series Lightweight Access Points

Keep these guidelines in mind when you use a 1200 series lightweight access point:

• The access points can only communicate with 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 Basic Service Set Identifiers (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 associated with 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 information, refer to the Appendix G,

“Configuring DHCP Option 43 for Lightweight Access Points.”

Checking the Top Panel LEDs

If your access point is not communicating, check the three LEDs on the top panel. You can use them to
quickly assess the unit’s status. Figure 7-1 shows the LEDs.

Figure 7-1 Access Point LEDs

Checking the Top Panel LEDs

The LEDs signals have the following meanings (for additional details refer to Table 7-1):

• The Ethernet LED signals traffic on the wired LAN, or Ethernet infrastructure. This LED is

normally green when an Ethernet cable is connected, and blinks green when a packet is received or
transmitted over the Ethernet infrastructure. The LED is off when the Ethernet cable is not
connected.

• The status LED signals operational status. Steady green indicates that the access point is associated

with at least one wireless client. Blinking green indicates that the access point is operating normally
but is not associated with any wireless devices.

• The radio LED blinks green to indicate radio traffic activity. The light is normally off, but it blinks

green whenever a packet is received or transmitted over the access point’s radio.

Manually Configuring Controller Information Using the Access Point CLI

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
to the console port, see the “Connecting to the Access Point Locally” section on page 7-9.

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.

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 <
AP# lwapp ip default-gateway
AP# lwapp controller ip address
AP# lwapp ap hostname

Where

name

is the access point name on the controller.

Note The default (out-of-box) Enable password is Cisco.

IP address

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

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(8)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.

Using a Controller to Return the Access Point to Autonomous Mode

Follow these steps to return a lightweight access point to autonomous mode using a controller:

Step 1 Log into the CLI on the controller to which the access point is associated and enter this command:

config ap tftp-downgrade

(where:

tftp-server-ip-address

a)

filename

b)
D:/Images/

c)
gondolier.)

Step 2 Wait until the access point completes the reboot, as indicated by the Status LED turning green to indicate

a client is associated or blinking green to indicate a client is not associated.

Step 3 After the access point reboots, reconfigure it using the access point GUI or the CLI.

tftp-server-ip-address filename access-point-name

is the full path and filename of the access point image file, such as

c1200-k9w7-tar.123-8.JA.ta

Returning the Access Point to Autonomous Mode

Using the MODE Button to Return the Access Point to Autonomous Mode

Follow these steps to return a lightweight access point to autonomous mode using the access point MODE
button and a TFTP server:

Note The access point MODE button is enabled by default, but you need to verify that the MODE button is

enabled (see the “MODE Button Setting” section on page 7-7).

Step 1 Set the static IP address of the PC on which your TFTP server software runs to an address between

10.0.0.2 and 10.0.0.30.

Step 2 Make sure that the PC contains the access point image file (such as c1200-k9w7-tar.123-8.JA.tar for a

1200 series access point) in the TFTP server folder and that the TFTP server is activated.

Step 3 Rename the access point image file in the TFTP server folder to c1200-k9w7-tar.default.

Step 4 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.

Step 5 Disconnect power from the access point.

Step 6 Press and hold the MODE button while you reconnect power to the access point.

Step 7 Hold the MODE button until the Radio LED turns red (approximately 20 to 30 seconds) and then

release.

Step 8 Wait until the access point reboots, as indicated by all LEDs turning green followed by the Status LED

blinking green.

Step 9 After the access point reboots, reconfigure it using the access point GUI or the CLI.

MODE Button Setting

The access point MODE button is configured from your controller. Use these controller CLI commands
