Airwave monitoring ClearPass -> Down

Hi folks,

 

fresh installation of customer consists of Airwave version 8.2.5.1  and ClearPass 6.7.0.101814. We successfully added mulptile different device types to Airwave for monitoring. But when i add ClearPass, it shown UP for ~5 minutes and than it turns to DOWN. Double checked community string and SNMP version. Airwave and ClearPass Data/External port are on the same subnet (ClearPass Monitoring port is not reachable for Airwave)

 

Alerts/Events for ClearPass:

Re: Airwave monitoring ClearPass -> Down

Did you add the CPPM server in as CPPM, Aruba Device, or Universal Network Device?  I'll have to try this out in the lab when I get a chance, but might find faster resolution by opening a TAC case.

This might be related to ClearPass issue #43392, which describes a stop of the SNMP service in ClearPass 6.7.0 when specific counters are queried by Airwave.

 

I would advise you to open a TAC case on ClearPass to verify if that is the issue.
