Does anybody know the OID or how I I can SNMP poll my CCM (4.1.3) to collect active PRI channels on my gatways?


Since I'm MGCP I figured I need to poll at the CCM and not the Gateway(s)


I've skimmed over the CISOC-CCM-MIB and saw nothing.

Kevin,


Here's the CCO documentation of CCM Perfmon Counters, RTMT and CCM-MIB.

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/service/4_2_3/ccmsrvs/ssappdxa.html


On that page you can find the Gateway Information for Performance Counters, RTMT, and CISCO-CCM-MIB.


http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/service/4_2_3/ccmsrvs/ssappdxa.html#wp1012907


The gateway information table includes information about a T1-PRI or E1 - PRI device. Each registered T1/E1 PRI port in Cisco IOS Gateway creates one instance of Cisco MGCP PRI Device. In the CCM-MIB, the ccmGatewayTable stores each T1/E1 PRI port as one device. Based on the registration status, ccmActiveGateways, ccmInActiveGateways, ccmRegisteredGateways, ccmUnregisteredGateways, and ccmRejectedGateways counters get updated.


Now go to the MIB Navigator, and locate the ccmGatewayTable. Its OID is 1.3.6.1.4.1.9.9.156.1.3.1, and its description is given as: "The table containing the list of all gateway devices which have tried to register with the local call manager at least once." Within that table, there's an object called ccmGatewayStatus, whose OID is 1.3.6.1.4.1.9.9.156.1.3.1.1.5 and whose desciption is "The status of the gateway. The Gateway status changes from Unknown to Registered when the Gateway registers itself with the local CCM." the values that this object returns are:

1:unknown

2:registered

3:unregistered

4:rejected

5:partiallyregistered

The CCM MIBS are located here:

Hope this helps.


Regards,

Michael.

I was wondering if anyone managed to get the OID to poll active channels from the CCM?

The OIDs mentioned in this conversation only tells you if the channels are registered/unregistered, etc, but nothing that can tell me if the channels are in use. Since I'm running in backhaul mode on the gateways, I can not see anything there either.


Thanks for any informatin.


Jorge.
