Cisco CMTS SNMP OID's
All:
Does anyone out there have some valuable OID's for a Cisco CMTS?
The ones I am looking for are:
Signal to Noise per upstream channel
Cable Modem counts of all kinds
connected / online
ranging
offline
I opened a ticket through Cisco's help desk. I have a SmartNET contract for
the unit, but they were not very helpful. The OIDs they suggested did not
yield any useful data. ("0" when I know there are CMs connected, etc).
Thanks in advance.

Not that you wouldn't have looked already but at the moment too much
information for me to consume I figured it would be worthwhile mentioning I
case you didn't know or maybe others as well.
ftp://ftp.cisco.com/pub/mibs/oid/
I've had some custom ones around in the past and if I can figure out where they
are held I'll shoot them your way.

1. Did you get the MIB for the CMTS from the Cisco web site?
2. What did you see when you did a SNMPWALK of the device?

What I currently do is take the walk of the above OID and get all that are a 6 and call that online modems. sam

Thanks all for your suggestions. I am now successfully graphing SNR for each upstream channel. -Original Message- From: Yang Yu [mailto:yang.yu.l...@gmail.com] Sent: Sunday, January 24, 2016 5:11 PM To: Lorell Hathcock Cc: NANOG list Subject: Re: Cisco CMTS SNMP OID's On Sun, Jan 24, 2016 at 1:06 PM, Lorell Hathcock wrote: > Signal to Noise per upstream channel CISCO-CABLE-SPECTRUM-MIB::ccsUpSpecMgmtSNR http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=ccsUpSpecMgmtSNR > Cable Modem counts of all kinds > connected / online > ranging > offline Not there if there are OIDs for `show cable modem docsis version summary`
Re: Cisco CMTS SNMP OID's
This is from some internal PHP thing that isn't very good (well, it's
lovely actually.. the problem is that it uses a forking method to query
everything and isn't that fast. I'm trying to rewrite it)
Throw any of these into google if you're confused about them. It should
return the correct MIB (except for the Casa ones. I'm not sure how I
found those but you can ignore them if you don't have any Casa CMTS)
'.1.3.6.1.2.1.10.127.1.3.3.1.2' => 'macs',
'.1.3.6.1.2.1.10.127.1.3.3.1.3' => 'ips',

'.1.3.6.1.2.1.10.127.1.3.3.1.9' => 'status', // genericstatus 0-7
'.1.3.6.1.2.1.10.127.1.3.3.1.13' => 'snr',
'.1.3.6.1.2.1.10.127.1.3.3.1.5' => 'dwnchnl', // this is actually
upchannel ifindex
'.1.3.6.1.2.1.31.1.1.1.1' => 'ifname',
// this is probably for any Cisco Docsis3 CMTS
if ($cmts['DeviceModel']['name'] == 'UBR7225VXR') {
unset($oids['.1.3.6.1.2.1.10.127.1.3.3.1.5']); // remove
dwnchnl, we'll get that from SNR
unset($oids['.1.3.6.1.2.1.10.127.1.3.3.1.13']);
$oids['.1.3.6.1.4.1.4491.2.1.20.1.4.1.4'] = 'snr';
}
switch ($cmts['DeviceType']['name']) {
case 'cisco':
'.1.3.6.1.4.1.9.9.116.1.3.2.1.1' => 'status2', // cisco
specific status cdxCmtsCmStatusValue
'.1.3.6.1.4.1.9.9.114.1.1.5.1.18' => 'flapcount',
'.1.3.6.1.4.1.9.9.114.1.1.5.1.10' => 'flaptime'
break;
case 'Casa':
'.3.6.1.4.1.20858.10.22.2.1.1.1' => 'status3',
// casa specific status (totally different values from cisco)

things you need to pull from each cable modem:
system.sysUpTime.0
transmission.127.1.1.1.1.6.3 down_pwr
transmission.127.1.2.2.1.3.2 up_pwr
transmission.127.1.1.4.1.5.3 down_snr
You can also pull the modems log via an OID but I don't have that one handy.

Re: Cisco CMTS SNMP OID's
Hi Lorell,
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:
.1.3.6.1.4.1.9.10.59.1.2.1
cable modem registrations:
.1.3.6.1.2.1.10.127.1.3.3.1
if you don't have remote query capability, then you can load the cable
modem ip from the registered list, and hit it with:
transmission.127.1.2.2.1.3.2
transmission.127.1.1.4.1.5.3
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:
1.3.6.1.2.1.10.127.1.1.4.1.4.%d&1.3.6.1.2.1.10.127.1.1.4.1.4.%d
and for SNR:
1.3.6.1.2.1.10.127.1.1.4.1.5.%d&1.3.6.1.2.1.10.127.1.1.4.1.5.%d
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
tools.
