Seeing the radio interfaces reset if RLDP is enabled is expected.  The AP needs to reset the radios because while RLDP is running the state of the radios has to be changed so that it can associate to other AP's.  There are bugs filed to have the trap messages be clearer to why the radios reset.

I am having similar problems, but we have not RLDP configured.

Whenever a AP changes channels, to reduce noise or interference, I recieve alarms stating as below;

802.11b/g/n interface of AP THA-A-AP-04 is down: Controller 10.218.100.251 Reason: Unknown.

802.11b/g/n interface of AP THA-A-AP-04 is up: Controller 10.218.100.251 Reason: Unknown.

Is there a way to reduce these messages or mitigate them? I still want to know if the AP goes down, but not every time there is a change in channel.

thanks

Hi

I upgraded my controllers version to 7.x and I don’t receive these kind of messages at all, usually I used to receive these kind of messages 10 times daily but right now I don’t receive it. May be you can try upgrading the software version.

Hi,

I have the same problem with LAP 1140 and WLC 6.0.199.0. I have also problems association and disassociation of the AP (from the wlc) and interruption of service for customers.

Deliver alarms (events) by WCS are as follows:

* 802.11b/g/n interface of AP AP02-AGP10-ERP is up: Controller 10.31.100.5

* 802.11b/g/n interface of AP AP02-AGP10-ERP is down: Controller 10.31.100.5

and

* AP 'AP02-AGP10-ERP' disassociated from Controller '10.31.100.5'.

* AP 'AP02-AGP10-ERP' associated with Controller '10.31.100.5' on Port number '...

The upgrade to the 7.x version in WLC was recommended by TAC?
