SNMP MIB/OID for Cisco 2800 ISR

I have several 2800 series routers setup as MGCP gateways with T1 PRI connections to the PSTN. Does anyone know what MIBs/OIDs to monitor for individual DS0 and DS1 activity? I opened a TAC case, but it wasn't very fruitful. Basically I just want to know how many active calls per PRI, averages, totals, uptime, etc.

For the 2800 about the best you can do is look at the CISCO-ISDN-MIB. unfortunately the ISR series routers do not fully support the CISCO-POP-MGMT-MIB.

If you are lucky you might be able to get some objects working in the POP-MGMT MIB

Re: SNMP MIB/OID for Cisco 2800 ISR

Do you know specifically which mibs will show what information though? For instance when I enter "sho snmp mib" I litterally get thousands of different mibs. If I enter "sho snmp mib | i isdn" that narrows it down quite a bit, but I still don't know what is relevant. isdnbearerentry.X, isdnendpointentry.x, isdndirectoryentry.x, etc, etc. Do you know which mib will tell me any good info with regards to monitoring call activity?

Re: SNMP MIB/OID for Cisco 2800 ISR

your best bet is to read the actual mib at:

You can read the text file and get a description of each object.

Some that you may want to look at include:

IsdnSignalingStatsEntry ::= SEQUENCE {

isdnSigStatsInCalls Counter32,

isdnSigStatsInConnected Counter32,

isdnSigStatsOutCalls Counter32,

isdnSigStatsOutConnected Counter32,

isdnSigStatsChargedUnits Counter32


If you're looking for something more voice specific:



DIAL-CONTROL-MIB: "callActiveTable"


DIAL-CONTROL-MIB: "callActiveCallState"
