Can anyone please help, my 1242 access points will not join my controller, I have done a debug and can see the Access point sending a discovery request, then the controller says discovery request sent, but then nothing happens, any ideas what this could be? I can ping the AP fine.
There are a number of things that could cause the join request to not show up. If there are no other controllers that the AP could be sending its join request to check to make sure there isn't a duplicate IP with your AP manager interface. Next if you are running LAG make sure the port-channel load-balancing on the switch that the controller is connected to is set to src-dst-ip.
