Here's ones that I used to use for DOCSIS 2 UBR's years ago. For the
remote query table, you will obviously need to turn on remote query.
remote query table:
cable modem registrations:
if you don't have remote query capability, then you can load the cable
modem ip from the registered list, and hit it with:
which gives you transmit power and SNR from the modem, which was all that
I cared about tracking. I would keep historical logs of the values and
graph over time - but never cleared it when the modem was returned and
re-issued, which yielded interesting graphs as the modem moved from
different plants over its lifetime.
For CMTS upstream errors, I graphed the following via MRTG:
and for SNR:
with %d being the ifindex of the upstream interface(s).
Your mileage may vary - this was from my toolsets for DOCSIS 1 and DOCSIS
2 environments, and I was out of the cable business when DOCSIS 3 became
affordable for smaller operators, so never had to worry about updating
