I just installed CER 2.0
Do we need to have an specific IOS version on the switches in order for CER to be able to poll the devices through SNMP ?
I can only associate 26 phones out of 462 to the proper switch port. the 26 phones are plugged to the same switch. If I check the application log it says
Failed to retrieve SysOid of a device 172.16.1.10 Please check if device is SNMP reachable. However all of the devices are SNMP reachable
C:\Program Files\OPENXTRA\NET-SNMP\usr\bin>snmpwalk -v2c -cCC_CALC 172.16.1.10 SysObjectID SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.9.1.614
This device is running IOS 12.2(25)SEE2
And the only switch that worked is running IOS 12.2(35)SE5
Please let me know
