Chapter 7 Controlling Lightweight Access Points

Autonomous Access Points Converted to Lightweight Mode

• In controller software release 4.2, all Cisco lightweight access points support 16 BSSIDs per radio

and a total of 16 wireless LANs per access point. In previous releases, they supported only 8 BSSIDs

per radio and a total of 8 wireless LANs per access point. When a converted access point associates

to a controller, only wireless LANs with IDs 1 through 16 are pushed to the access point.

• Access points converted to lightweight mode do not support Layer 2 LWAPP. Access Points

converted to lightweight mode must get an IP address and discover the controller using DHCP, DNS,

or IP subnet broadcast.

• After you convert an access point to lightweight mode, the console port provides read-only access

to the unit.

• The 1130AG and 1240AG access points support hybrid-REAP mode. See Chapter 12 for details.

• The upgrade conversion tool adds the self-signed certificate (SSC) key-hash to only one of the

controllers on the Cisco WiSM. After the conversion has been completed, add the SSC key-hash to

the second controller on the Cisco WiSM by copying the SSC key-hash from the first controller to

the second controller. To copy the SSC key-hash, open the AP Policies page of the controller GUI

(Security > AAA > AP Policies) and copy the SSC key-hash from the SHA1 Key Hash column

under AP Authorization List (see Figure 7-21). Then, using the second controller’s GUI, open the

same page and paste the key-hash into the SHA1 Key Hash field under Add AP to Authorization

List. If you have more than one Cisco WiSM, use WCS to push the SSC key-hash to all the other

controllers.

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.
