Error in query for information for an AP

[renzanjo-caparas]

Hi!

I have received this event message in our monitoring tool. 

%APMGR_TRACE_MESSAGE-3-EWLC_RRM_QUERY_ERR: Chassis 1 R0/0: wncd: Error in Query for information for an AP

I've checked the AP and it's been up and reachable from the controller for weeks already.

Anybody experienced this issue as well?

WLC use RRM to assign correct RF for each AP' 

Here your AP can not talk to other AP to send info to WLC.

Hi @MHM Cisco World ,

Thank you for this input. Apologies as this is one I am not familiar with. But how could I check whether it's working fine now or issue is still persisting? The alarm was only triggered once around 2 hours ago as of this writing and I don't see any same alarms now.

Thanks!

Hi @MHM Cisco World ,

I am trying to read your input back and forth and I think I got your point.

WLC uses RRM to assign correct RF For each AP. And while RRM is in process, AP cannot talk to the other AP and send info to WLC.

Am I correct?

Hi 

Yes' AP talk to each other and send result to wlc' elc run RRM to select correct RF

Check this

Thanks

Hi! I have noted this. However, do we have any updated document for this? I am trying my best to check for any updated document for this but i cannot see any which explicitly states that AP cannot hear each other.
