Hi,

we want to create a report (or even better, a graph on the node details page) about Bearer Channels (each one is an interface).

 

We would like to see a graph with min/max/average amount of those channels being used on that node.

Has anyone already created something similar?!?

Hi,

I have browsed for all kinds of MIBs but none seem to be reliable for BRI and PRI.

What I have done to solve the problem is create a custom poller for OID 1.3.6.1.2.1.10.20.1.2.1.1.2 (returns a table with all B-channels and shows if they are active etc.) and created an advanced SQL query report to give me the maximum amount of channels used per day and per device.

Now I have it as a report which is fine for me but is there any way to implement that into a graph for each node? Or if there is not have the report be displayed on each node but have that report automatically filter so that only that one node will be displayed?

What kind of device/hardware are the POTS interfaces on?  Are you looking for utilization on the min/max/avg utlization on the interfaces or looking for how many of the interfaces are being used?

I am monitoring this OID for active calls on a PRI:

1.3.6.1.4.1.9.10.19.1.1.9.1.3 (CISCO-POP-MGMT-MIB:cpmDS1ActiveDS0s)

You have to add the slot/port number to the end; e.g. "1.3.6.1.4.1.9.10.19.1.1.9.1.3.0.0" for slot 0/ port 0. Add this as a UnDP and plot it with whatever graph you like.

See the following for info about different ISDN MIB's.  PRI and BRI are in different places.  For PRI (E1 and T1 lines), the physical interfaces are managed by the DS1/E1 MIB.  See the following:

http://www.cisco.com/en/US/docs/ios/12_0t/12_0t1/feature/guide/isdn_mib.html

Functional Description

The ISDN MIB RFC 2127 is designed so that network management systems and agents on routers will work together to provide important data and statistics about the ISDN interfaces.

The implementation of the new ISDN MIB RFC 2127 does not remove the current support of Cisco's proprietary ISDN MIB.

The support for the ISDN MIB RFC 2127 needs to be bundled with Cisco's proprietary ISDN MIB because the MIB RFC 2127 uses the current MIB's trap generation.

Cisco's ISDN MIB and RFC 2127 work independently; therefore, one can be disabled while the other is enabled.

The ISDN MIB RFC 2127 consists of five groups:

•ISDN Physical Interface Group

•B (Bearer) Channel Group

•D (Signaling) Channel Group

•Terminal Endpoint Group

•Directory Number Group (optional)

ISDN Physical Interface Group

This group provides information regarding the physical BRIs. For PRI (E1 and T1 lines), the physical interfaces are managed by the DS1/E1 MIB, which is not a part of this feature.

Hey,

This is exactly what I'm trying to work out at the moment :) I've been collecting the data using the same OID you mentioned for a while now, but as my SQL knowledge is minimal at best I'm having trouble extracting a usable report from it. Care to share how you went about it?

Cheers in advance,

Jason

I do, thanks :)

Well except of putting it into a graph and hiding the report on the nodes page if the custom poller is not assigned to that node... :(
