OTAP Process
During the LAP boot process, the LAP uses different mechanisms in order to discover controllers that it can
join. The LAP keeps each of the controller that IP addresses it learned through the different methods in
different lists in order to reflect how the LAP learned about them. For example, the LAP can learn
management IP addresses of multiple controllers through the DNS entry for
CISCO−LWAPP−CONTROLLER.localdomain, DHCP option 43, through broadcasts on the local subnet,
locally stored controller IP address discovery, and through OTAP. Once the access point has completed the
LWAPP WLC Discovery steps, it chooses a WLC from the candidate WLC list and sends that WLC an
LWAPP Join Request.
