Hello,
we need a snmp oid for monitoring active isdn calls on a cisco 3825 running 12.4(15)T7 with VWIC2-2MFT-T1/E1 modules. OID cpmISDNCfgBChannelsInUse doesn't work, we get always 0 even if there are active calls.

The CISCO-POP-MGMT-MIB has many caveats with the MAR/ISR platforms. It was designed only for the AS5xxx platforms. As a workaround for cpmISDNCfgBChannelsInUse, you can count the number of instances of isdnBearerOperStatus that return the status of active (integer 4).

thank you for your response. i know we can use the isdnBearerOperStatus object but we have 12 e1 interfaces that means we have to poll 360 b channels which is quiet inconvenient.

You might also try cpmDS1ActiveDS0s or cpmActiveDS0s, but they are also known to be buggy on this platform.

ok i'll check this

Hi Joseph,
You appear to know more than most about this issue, so I will dump my query below from another string in the forums:
Please note in the output below that your suggested use of the "isdnBearerOperStatus" variable does not work in my two routers as shown. There were most definitely active channels at the time that the query was run, yet the response is always the same - status: idle (1) so I remain unable to get these stats successfully across both routers.
Any suggestions ?
I am running into exactly the same issue and have tried everything I can find to get these individual PRI (count of channels/lines in use) statistics.
Just for the record, here are some of the SNMP OIDs that I have tried (the ISRs do respond to them, only thing is, the data they send back is mostly rubbish...) the output below is from two separate routers, with different versions of IOS running (which is shown in the sysdescr response):
Note that the query in red in the second router was responded to with a valid response in the FIRST router...
All of these OIDs have been suggested at various sites online as useable SNMP OIDs for the ISR, but at other sites, they are suggested to be faulty. I have found no definitive statement for ways to get these stats successfully on the ISR platform (which amazes me.) Output below is using net-snmp to collect the stats.
I welcome any suggestions as to how this can be done reliably for the ISR, and what IOS versions WILL work. (since I am getting way different reponses to the same OIDs on the two versions below).
You'll see that for the second (DC) router below, the values are always Zero.
Yet I can guarantee that the ACTUAL stats are NEVER zero during the time period queried.
