One of our Access-Point is continually failed to register on the controller.
Any idea what it could be or what can be done.
Have you verified that option 43 is configured for the scope that these APs are supposed to be in? Are they additions to an existing network?
I have tried resetting the port but is is bouncing, and when I do a search on the WLC via mac-address it won't find it.
It worked fine for a while when we swapped to a different port and now it happening again.
Can you console into the AP that WON'T register/associate to the WLC? If so, do the following:
1. Make sure the AP can ping the WLC Management IP Address; and
2. Type the command: lwapp ap controller ip address
Does this help?
On the CLI of the controller, run the following debugs:
debug mac addr < mac address of the AP>
debug lwapp events enable
debug pm pki enable
This should help you narrow down why the AP is not joining the controller.
