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. -- Jason Hellenthal JJH48-ARIN On Jan 24, 2016, at 13:06, Lorell Hathcock <lorell@hathcock.org> wrote: All: Does anyone out there have some valuable OID's for a Cisco CMTS?

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.

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?

Not there if there are OIDs for `show cable modem docsis version summary`

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.2.1.10.127.1.3.3.1.9 I don't know of an OID that will say 'X number of modems online', if anyone does, please share. 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.list@gmail.com] Sent: Sunday, January 24, 2016 5:11 PM To: Lorell Hathcock <lorell@hathcock.org> Cc: NANOG list <nanog@nanog.org> Subject: Re: Cisco CMTS SNMP OID's On Sun, Jan 24, 2016 at 1:06 PM, Lorell Hathcock <lorell@hathcock.org> wrote:

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', '.1.3.6.1.2.1.10.127.1.3.3.1.6' => 'rxpwr', '.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) '.1.3.6.1.4.1.20858.10.11.1.2.1.10' => 'flaptime', '.1.3.6.1.4.1.20858.10.11.1.2.1.9' => 'flapcount' ---------------------------------------------------------------------------------------------------------------------- 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.
