Anyone seen this one? I have a TAC case pending on it...
CER is Version 2.0.3
CCM is version 6.1(1)
CER is refusing to communicate via SNMP with the CUCM. CUCM communities have been checked and rechecked, they have also been tested with a 3rd party SNMP tool (GETIF) to make sure they do respond. Boxes can ping each other. CER does register it's route points.
Syslog error message thrown when the phone update processes is
08-16-2008 17:28:45 Local7.Debug 10.15.1.30 %CER_CER_AGGREGATOR-6-INFO:Device 10.15.1.10 is SNMP unreachable. Please check SNMP settings in CER and also on this CCM. Please confim proper access previlage ( READ_ONLY ) set on this box for SNMP service. Also, verify n/w connectivity.
The result is that CER isn't learning about any of the phones in the CUCM.
We have tried
removing CUCM from CER and put back
retype/recheck all SNMP community strings
reboot all involved servers
