I have configured option 43 on dhcp server, rebooted 1131 AP, but AP always try to resolve CISCO-LWAPP-CONTROLLER instead of ip provided by dhcp. How can I debug this?
Config on router:
ip dhcp pool seg20
option 43 hex f104.0a0f.64fd
A CUWN AP, goes through all methods of discovery. So it always attempts to use DNS, option 43, L3 broadcast, L2 broadcast. Once it has discovered, then it will unicast the Join request.
