WLC Controller Discovery

Is there a way to clear the "Previously known" list from the Access Point so it does not use those controllers to join without wiping the entire AP configuration?

Discover Process:

Local Broadcast Layer 2: Used on 10x0 and 1510 AP’s that support the LWAPP Layer 2 protocol.
Local Broadcast Layer 3: Supported by all AP’s, this discovery method uses UDP with destination 255.255.255.255
Option 43
DNS
Previously known
Statically configured from WLC
Over the Air Provisioning (OTAP): AP’s put the radios in “listening” mode to try to hear neighbor exchanges between nearby AP’s
Statically configured from AP

Depending on the firmware/IOS of your AP.

Power up the AP (don't connect to the LAN) and in enable mode enter the command "clear lwapp ap controller ip address".

If the error message "Command disabled" comes up then you need to boot to the "rcv" image. This can be achieved by making sure you have a "rcv" image in the AP and deleting the LWAP IOS on the AP. Reload the AP and run the command again.
