cpmDS1DS0UsageTable cover only some interface

[sb-txr-cco]

Hi,

i use cpmDS1DS0UsageTable MIB to monitor how many DS0 are used for each DS1.

But not all active interface are covered. In specific i have 4 E1 interface (two in VWIC0, one in VWIC1 and one in NM):

0/0/0

0/0/1

0/1/0

1/0/0

in the snmp walk i can see only 3 of those interface (no cover for interface 0/1/0). the output of snmpwalk is:

SNMPv2-SMI::enterprises.9.10.19.1.1.9.1.3.0.0 = Gauge32: 0

SNMPv2-SMI::enterprises.9.10.19.1.1.9.1.3.0.1 = Gauge32: 0

SNMPv2-SMI::enterprises.9.10.19.1.1.9.1.3.1.0 = Gauge32: 0

the mapping is:

0/0/0 9.0.0

0/0/1 9.0.1

0/1/0 not covered

1/0/0 9.1.0

Someone has an idea of why one interface is not seen??

Thanks

Stefano

You're not going to get reliable CISCO-POP-MGMT-

MIB support from non AS5XXX platforms. See http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Network%20Infrastructure&topic=Network%20Management&CommCmd=MB%3Fcmd%3Dpass_through%26location%3Doutline%40%5E1%40%40.1dddf22e/0#selected_message and CSCee16176 for more details.

Thanks, now it's clear but i don't find any other MIB that gives the DS0 usage inside the specific E1.

Any idea on which MIB has the same function?? the bug toolkit doesn't report any useful alternative.

Depending on the configuration, the ISDN-MIB and the isdnBearerOperStatus object may be of use.

That MIB gives you the status of the single DS0. What i'm looking for is the value of used DS0 inside a DS1 (how many DS0 is simultanuosly used).

That object gives wrong information like show isdn active. As you can see from this output 10 outgoing calls are reported as active but no B channel are up (last call was at least 12 hours before):

The other choices for this platform are trying to use the CISCO-VOICE-DIAL-CONTROL-MIB or the DIAL-CONTROL-MIB (e.g. see the callActiveTable), or write a script to parse the CLI, and perform the calculation you need.

For the latter solution, assuming you're running 12.3(2)T or higher, you can use the embedded tclsh engine to build a customer show command to provide this data. See http://www.cisco.com/en/US/products/sw/iosswrel/ps5207/products_feature_guide09186a00801a75a7.html for more on TCL scripting in IOS.
