I have a 2821 router running 12.4(3g) with a channelised E1 interface, and I want to monitor how many DS0s are in use for capacity planning purposes.
I do this with some older 3640 routers by graphing the mib object cpmActiveDS0s (.126.96.36.199.188.8.131.52.184.108.40.206) and that works just fine, but the 2821 returns an absurdly high number as follows;
snmpwalk -c community -v 2c 2821_rtr .220.127.116.11.18.104.22.168.22.214.171.124
SNMPv2-SMI::enterprises.126.96.36.199.1.4.0 = Gauge32: 3615
There are only 12 channels on the system so the number 3615 is junk! Is CISCO-POP-MGMT-MIB not supported on the newer routers (2800 etc.)? If so how can we get the data that we need to manage the device effectively?
