Airespace WLC: Interface 802.11b/g down on controller ''

chris.van.krieken — Sun, 04 Jul 2021 18:25:45 GMT

I am using 13 WLC4404-100 switches (version 3.1.105.0)., with about 200 1010 APs. We are regularily getting messages in the eventlog like :

AP 'ap:25:1d:e0', interface '802.11b/g' is down on Controller ''.

After 1 minute: AP 'ap:25:1d:e0', interface '802.11b/g' is up on Controller '195.130.142.36'.

There is no disassociate or associate message preceding this.

Does some one know what this message indicates and why is the radio interface going down ?

I think the issue is link flaps.The problem may be with the interface like

1.speed

2.duplex mismatch

3.encapsulation mismatch.
