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
Reset Button on Access Points Converted to Lightweight Mode” section on page 7-33
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.
