Thanks Bob, but I'm not the one looking for the information on how to track
number of channels on the 26xx. I'm already tracking this successfully on a
5350 using the OID I listed.
However, my application is a little different than Dave's. I am tracking
B-channel usage on a remote access dial-in server fed by multiple PRI lines.
Dave wants to track B-channel usage on a VOIP gateway. The principle is the
same however; if the device supports CISCO-POP-MGMT-MIB the OID I use should
also work for Dave. This is not a table entry, just a regular gauge.
A couple other OIDs in this MIB that might work are:
cpmISDNCfgBChanInUseForAnalog
.1.3.6.1.4.1.9.10.19.1.1.2.0
The number of configured ISDN B-Channels that are
currently occupied by analog calls.
cpmISDNCfgBChannelsInUse
.1.3.6.1.4.1.9.10.19.1.1.3.0
The number of configured ISDN B-Channels that are
currently occupied by both Digital and Analog calls.
cpmPPPCalls
.1.3.6.1.4.1.9.10.19.1.1.5.0
The current number of active PPP calls received
by the managed device
cpmV120Calls
.1.3.6.1.4.1.9.10.19.1.1.6.0
The current number of active V.120 calls received
by the managed device
cpmV110Calls
.1.3.6.1.4.1.9.10.19.1.1.7.0
The current number of active V.110 calls received
by the managed device
There's also a table called cpmDS1DS0UsageTable, which has values broken
down by individual DS1 interfaces. For example, cpmDS1ActiveDS0s
(.1.3.6.1.4.1.9.10.19.1.1.9.1.3.3.x, where x is the DS1 number starting at
0) shows the number of B-Channels in use on each PRI. I just noticed that
cpmDS1ActiveDS0sHighWaterMark (.1.3.6.1.4.1.9.10.19.1.1.9.1.4.3.x) actually
gives the maximum number of channels that have ever (since last reset) been
used on each DS1, while cpmActiveDS0sHighWaterMark
(.1.3.6.1.4.1.9.10.19.1.1.8.0), which should be the aggregate of all DS1's,
doesn't work. Probably some bug in the agent.
Here's a section of my config. Note that the Max. Users number I have in
there doesn't work; but no one ever asked to have it fixed...

Jerry,
The CISCO-POP-MGMT-MIB is supported in V1 and V2 format for certain IOS
releases on the 26xx platform.
However, in order to access the information, you would have to look into a
table using three indexes (cpmDS1SlotIndex, cpmDS1PortIndex,
cpmChannelIndex);
The below information looks like it might give you utilization information
for a single ds0.
As far as summing them up with MRTG, I'd be interested in seeing the cfg
file (assuming this works). It may require some pre processing before
sending it to MRTG.
