[mrtg] Re: Monitoring traffic on modem cable behind DOCSIS and Terayon Gateway

[Cristian Piatnitchi]

Hi

Here in Canada the IP you get corresponds to a DNS records like this

CPE0007952497b4-CM400049186934.cpe.net.cable.rogers.com

You may easily see that the CPE means Customer Premise Equipment
And CM = Cable Modem. It never changes !! (the numbers are the MAC
addresses of the devices
The NIC card and the modem) The IP does.
Try to use this DNS name.

Please could you tell me how would you access the SNMP and the modem if
the modem is not under your management ?

Subject: [mrtg] Monitoring traffic on modem cable behind DOCSIS and
Terayon Gateway


Hi,

I'm actually using mrtg to monitor the traffic and the bandwidth usage
for some machines which have fix ip adresses. (especially DSL clients).
Now I would like to monitor the same kind of things for our cable
clients who are behind DOCSIS and Terayon Gateway. The problem is that
they didn't have a fix ip address. So the only way (I think?) to monitor
them directly is by using the Mac address of their cable modem. Is there
a tool using MRTG (a contrib?) to do such thing or can MRTG get the
informations I need (so the traffic per modem) by polling the DOCSIS /
Terrayon directly. (Is their an OID for that?)

I found on the net that it seems possible to monitor Terayon with snmp.
But how can I get infos per modem??? Thanks in advance for your tips!
