Hi everyone!
A customer's WLC its droping APs, in the log says the physical port was up then down, (logs attached), I look into the sw which is connected to the WLC but i couldn't find anything. could be possible that a speed mismatch or some PoE issue causes the port to restart ?
I'd really apreciate your help!
Kind regards!

Is this match with the WLC uptime ?
As you can see those stats, there is no indication of any layer 2 errors

Yup, the customer told me they turned off the WLC and some switches in order to install a new UPS, but the issue was before this disconnection.
I understand since the counters were cleared we can not see any further information, right? or is there a way ?
Kind regards!
