Chapter 7 Controlling Lightweight Access Points

Autonomous Access Points Converted to Lightweight Mode

Reverting from Lightweight Mode to Autonomous Mode

After you use the upgrade tool to convert an autonomous access point to lightweight mode, you can

convert the access point from a lightweight unit back to an autonomous unit by loading a Cisco IOS

release that supports autonomous mode (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. In either method, the

access point must be able to access a TFTP server that contains the Cisco IOS release to be loaded.

Using a Controller to Return to a Previous Release

Follow these steps to revert from lightweight mode to autonomous mode using a wireless LAN

controller:

Step 1 Log into the CLI on the controller to which the access point is associated.

Step 2 Enter this command:

config ap tftp-downgrade tftp-server-ip-address filename access-point-name

Step 3 Wait until the access point reboots and reconfigure the access point using the CLI or GUI.

Using the MODE Button and a TFTP Server to Return to a Previous Release

Follow these steps to revert from lightweight mode to autonomous mode by using the access point

MODE (reset) button to load a Cisco IOS release from a TFTP server:

Step 1 The PC on which your TFTP server software runs must be configured with a static IP address in the range

of 10.0.0.2 to 10.0.0.30.

Step 2 Make sure that the PC contains the access point image file (such as c1200-k9w7-tar.123-7.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 for a 1200

series access point.

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.

Note The MODE button on the access point must be enabled. Follow the steps in the “Disabling the

Reset Button on Access Points Converted to Lightweight Mode” section on page 7-34 to check

the status of the access point MODE button.

Step 7 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds), and release the

MODE button.
