I know the AP goes through a series of steps to discover a controller. I've read that it checks DHCP Option 43 **BEFORE** checking DNS for CISCO-LWAPP-CONTROLLER.localdomain. And, the AP compiles a list of candidate controllers.
My question is:
Does it use BOTH the set of controllers given in DHCP Option 43 -AND- in DNS? Or, if it sees an Option 43, does the discovery end there?
