Cable Modem Counters

Does anyone know the SNMP OID to access these numbers from a Cisco CMTS

Currently we poll the modems for ds/us byte counts but docsis 3 now requires multiple interfaces or service flows, and the CMTS seems to consolidate these numbers for accounting so there has to be some way for us to poll the cmts every 5 minutes using the mac address to get these counters..

Or a linux script to telnet

Or a linux script to SSH to the CMTS and dump the entries to an array for mrtg processing :)

Getting closer, using RANCID

Getting closer, using RANCID with Clogin to process the command in a bash script.. now I need to parse it and pump it to rrd :) anyone???

IPDR

Hi,

IPDR is a solution for you. It is basicaly what you need and it is meant to do what you're doing.

If you only need to parse this into rrd it's pretty straightforward:
You need to create rrd with 4 DS. They must be counters.
and you just do rrdtool update .rrd N:DS1:DS2:DS3:DS4

You can do this with bash script or prefferably python/perl/php

BR,
Bajo

I don't have an IPDR receptor

I don't have an IPDR receptor and it doesn't look as if there are many open source resources for it anymore. How are you grabbing the data or receiving it, and how do you know the timeframes.

Thanks for those OID's

Thanks for those OID's Johnson, where did you find the match to the show cable modem mac-address counters, are there ones for US Bytes and US Packets? I searched everywhere for those.
