Controller Discovery Process

The access point supports these controller discovery processes:

•Layer 2 LWAPP discovery—Only sent on the same subnet as the access point and uses encapsulated Ethernet frames containing MAC addresses for communication between the access point and the controller. Encapsulated Ethernet frames are not suitable for Layer 3 deployments where the controller is not on the same subnet as the access points.

•Over-the-air wireless discovery—If enabled on the controller, all the associated access points transmit wireless LWAPP neighbor messages. New access points receive the controller IP address from the wireless LWAPP neighbor messages. This feature should be disabled when all access points are installed. Also, this feature is only supported by Cisco1000 series lightweight access points and Cisco 4400 controllers.

•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-volatile 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 Access Points Prior to Deployment” section on page E-1.
