Hi Rene,
I have an issue with an AP not joining the WLC, I have 3 AP’s on the WLC, one of them keeps drop the connection, when I check it by show cdp nei deta it has the correct IP address and it’s up on the switch, I can bring it back up by bouncing the port but it will come up for less than 3 minutes or so, please check the debug below on the WLC.
Note: the IP address and MAC address is hidden for privacy purposes.
Thanks in advance
