I have been running two 4402 controllers and about 40 LWAPP access points locally (region) for some time now. I have been leveraging the option 43 I believe in DHCP and specifying my controllers for some time now since I wasn't going to bother with DNS resolution for CISCO-LWAPP-CONTROLLER.corp.cox.com
Well now someone at a corporate level has gone and setup DNS resolution for CISCO-LWAPP-CONTROLLER.corp.cox.com and my AP's are now resolving this and connecting to those controllers.
Even when I connect via the console to the AP and try to specify lwapp controller ip address I get:
ERROR!!! Command is disabled.
I know Cisco tried to make life a little easier for others in doing this but its pretty stupid.
