Error: Config Sync failed on Standby for the usmdb: HA_send_usmDbApf80211BrxSenSopThresholdApSet

[awsalazar90]

Hi guys,

I have a pair of WLC 5520 in HA SSO and I have received an alarm through my cisco prime, could someone give me information regarding this alarm:

1. Message: Redundancy Failure Event trap triggered by Controller 'x.x.x.x' for the reason 'Error: Config Sync failed on Standby for the usmdb: HA_send_usmDbApf80211BrxSenSopThresholdApSet, ReasonCode: 1'

when I verify the secondary WLC I see the same message, I wanted to know what the message refers to; and if there is any way to validate if there is currently a problem.

The issue you are having sounds like a possible code bug,  What version of code are you running on the wireless controllers ?

Hi, the Software Version is 8.5.140.0

I very rarely also see config sync error messages. Typically waiting some hours or clicking on the Save button makes them disappear.
There would be a bit newer software out: https://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/crn85mr5.html

It fixes this bug: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCut85555
I don't think it's the same issue, but might share the same code source.
