Voice T1/E1 SNMP

Anyone here know an easy way to configure an SNMP app like MRTG to monitor the utilization of a T1 Voice Channel Module. I would like to be able to monitor usage and determine when a new T1 would need to be ordered.

Re: Voice T1/E1 SNMP

I use MRTG to monitor usage on our 5300s but I can't seem to get it to work on a Cat. WS-X6608-T1 anyone know how to do it on the Catalyst?

On our AS5300s I use MRTG to monitor values in ciscoPopMgmtMIB. For a chassis total use cpmActiveDS0s ( and

cpmActiveDS0sHighWaterMark* (

*Note: This high water mark is simply a sum of the individual circuit high watermarks. It is NOT necessarily the maximum number of DS0s in use simultaneously. Would be nice if Cisco changed this to max. simultaneous in use.

For individual circuits monitor values in the cpmDS1DS0UsageTable: cpmActiveDS0s ( and cpmActiveDS0sHighWaterMark (

Unfortunately those OID's don't work on the 3640 / NM-HDV-T1 Card we are trying to monitor.

Hopefully more people will respond. :)
