Cisco CUCM IP Phone SNMP OID keep changing http://developer.cisco.com/c/message_boards/find_thread?p_l_id=&threadId=4869633 2013-05-22T19:27:00Z 2013-05-22T19:27:00Z subash cobi http://developer.cisco.com/c/message_boards/find_message?p_l_id=&messageId=4869632 2011-12-09T08:41:34Z 2011-12-09T08:38:21Z

Hi, I have a CUCM 7.X which send SNMP alerts to a 3rd party SNMP server. We notice that the OID value for all individual IP Phone keep changing from the SNMP server. Example: 23/11/2011 ------------- OID=.1.3.6.1.4.1.9.9.156.1.2.1.654 OID=ccmPhoneDescription.654 Value=Zulkarnean bin Zainal Abidin OID=.1.3.6.1.4.1.9.9.156.1.2.1.703 OID=ccmPhoneDescription.703 Value=Norhayu binti Razli 06/12/2011 ------------- OID=.1.3.6.1.4.1.9.9.156.1.2.1.923 OID=ccmPhoneDescription.923 Value=Zulkarnean bin Zainal Abidin OID=.1.3.6.1.4.1.9.9.156.1.2.1.754    OID=ccmPhoneDescription.754 Value=Norhayu binti Razli   Is there a way to ensure the OID of each IP Phones remains the same. This is because the SNMP server has to match these individual phone based on the OID to an Floor layout, so users would know where exactly are the phones located.   Attached is screen shot of the MIB browser on the 23/11/2011 and 06/12/2011. You can see that the same phones get different OID for these 2 days.   Appriciate any comments on how to get this right.   Thanks, Subash
