ACCESS UNABLE TO JOIN CONTROLLER

[ugwuugochukwukizito]

Hello All, 

I have a 2504 WLC at the office, and about 2 AIR-LAP1142N-E-K9. We moved to a new office space and since then, the access points have not been able to join the controller.

I have attached the debug output.

Kindly assist!!!

Cant see it in the log attached, but check out

Both that WLC and AP model are affected by this field notice

Hello Andrew,

Many thanks for your response. I read through the field notice you attached and it was helpful.

I issued the commands below on the controller:

ap cert-expiry-ignore ssc enable

ap cert-expiry-ignore mic enable

In addition to the commands above, I changed the time on the controller to an earlier date and the Access points were able to register.

Thanks once more.
