CER 7 SNMP Switch port phone tracking

I have configured the snmp community strings and the switch ip in CER for Phone tracking. After running switch-port & phone update I am not able to see the switch under ERl membership Switch ports. How can I correct this issue? CER Log tracking below:

274: Mar 26 15:23:59.425 EDT %CER-CER_PHONETRACKINGENGINE-3-ERROR:CER Message Receiver T:SysOidPredicate      getSysOid            SnmpException - SnmpRequestTimeout on while performing SnmpGet at index = -1 for ipAddress=
275: Mar 26 15:23:59.425 EDT %CER-CER_PHONETRACKINGENGINE-3-ERROR:CER Message Receiver T:CoreSortSeedDevices  isSuccefullyAddedInD SNMP Error SnmpRequestTimeout on while performing SnmpGet at index = -1 in retrieving sysOid, ignoring device for this cycle of discovery

Any help is appreciated.

Configuration register is 0xF

Hi Emanuel,

SSH to the CER server, and run the following command : 'utils snmp get 2c'

Example : if the SNMP community string is test, the command would be utils snmp get 2c test

Check if you get the output of '' (

Also check if you can ping the switch from the CER server (utils network ping

From the switch perspective, check if the community string is configured exactly how it is done on CER (snmp-server community test RO)
