I am looking to read optical transmit and recieve power of XFPs in our ASR9k. The MIB used should be "CISCO-ENTITY-SENSOR-MIB" which is 1.3.6.1.4.1.9.9.91 and occording the ASR9000 documentation, this is available on ASR9k's: http://www.cisco.com/en/US/docs/routers/asr9000/mib/guide/asr9kmib3.html#wp2293135 If you scroll up, you will see that the MIB is in the supported list.

So, my question: am I missing something and should this information be available to SNMP, or is the Cisco documentation wrong here? And if it is available, how can I get to this information?

However show snmp mib object-name | i 1.3.6.1.4.1.9.9.91 gives me nothing neither does show snmp mib object-name | i Sensor

RP/0/RSP0/CPU0:router#show snmp mib object-name | i 1.3.6.1.4.1.9.9.91 Thu May 16 09:08:01.679 CET RP/0/RSP0/CPU0:router#show snmp mib object-name | i [sS]ensor Thu May 16 09:08:19.017 CET

The version:

RP/0/RSP0/CPU0:router#show version Thu May 16 09:07:14.437 CET

And the XFP I am trying to read:

RP/0/RSP0/CPU0:router#show inventory NAME: "module 0/0/CPU0", DESCR: "8-Port 10GE Low Queue Line Card, Requires XFPs" PID: A9K-8T-L, VID: V04, SN: FOC1641N6EH

To compare, this is the output from our 7606:

7606#show ver Cisco IOS Software, c7600s72033_rp Software (c7600s72033_rp-ADVIPSERVICESK9-M), Version 15.1(3)S4, RELEASE SOFTWARE (fc2)

Have you tried walking the MIB/OIDs in question from a management station? After having spent a lot of time w/firmware QA, I've noticed things like show commands are likely to not display correct info, even when the OIDs are poll-able. I recommend using and knowing Net-SNMP tools and utils as debug before trying to poll the information in cacti, observium, etc.

e.g. snmpwalk -v2c -c <community> <routername> 1.3.6.1.4.1.9.9.91 will say "No Such Object available on this agent at this OID" if it's not there

Walking 1.3.6.1.4.1.9 on my IOS-XE box gives a lot (I just need to add the MIBs for description). Then I have something to work with (including other gems that might benefit me for monitoring)

snmpwalk -v2c -c <community> <routername> 1.3.6.1.4.1.9

Check out the MIBs available for 4.2.x on the ASR 9000 @:

ftp://ftp.cisco.com/pub/mibs/supportlists/asr9000/asr9000-supportlist.html#Supported_and_Verified_MIBs_XE_4_2_X

That link says that the CISCO-ENTITY-SENSOR-MIB is available, and hasn't been updated since 2007. Edit: it appears that the asr9k-mgbl-p.pie package was not available on the router, as mapped in the ASR9000 MIB list above.

Supplemental info:

Cisco's MIB Locator tool is IOS-only, so check out the directories above above the asr9000 on the FTP link for more info.

Tool: http://tools.cisco.com/ITDIT/MIBS/MainServlet

SNMP ftp dir: ftp://ftp.cisco.com/pub/mibs/supportlists/

A really good Cisco SNMP links page: http://www.cisco.com/en/US/tech/tk648/tk362/tk605/tsd_technology_support_sub-protocol_home.html

  • I seem to be missing the Cisco IOS XR Manageability Package (asr9k-mgbl-p.pie). I will update this in a next service window. Thank you so much. – JelmerS May 16 '13 at 9:59
  • asr9k-mgbl-p.pie was missing? Possibly from an upgrade? Either way, I'm holding on to those SNMP links I just found - handy :) – lunistorvalds May 16 '13 at 10:05
  • I am new at this LIR, so I don't know the reason behind the missing pie. However, on a different ASR, the pie IS installed, and I can indeed get the Tx and Rx power in mW. – JelmerS May 16 '13 at 11:36

The mib 1.3.6.1.4.1.9.9.91 works on ASR1001s at least.

Running the following from my monitoring box:

snmpwalk -v2c -c <community-string> <asr1001-name> 1.3.6.1.4.1.9.9.91

Gives an output of:

CISCO-ENTITY-SENSOR-MIB::entSensorType.4 = INTEGER: amperes(5)
CISCO-ENTITY-SENSOR-MIB::entSensorType.5 = INTEGER: voltsAC(3)
CISCO-ENTITY-SENSOR-MIB::entSensorType.6 = INTEGER: voltsAC(3)
CISCO-ENTITY-SENSOR-MIB::entSensorType.7 = INTEGER: celsius(8)
CISCO-ENTITY-SENSOR-MIB::entSensorType.8 = INTEGER: celsius(8)

And so on. You'll just have to index it and find the particular sensor you wish to monitor.

(As a note, to get readable output, I had to install the CISCO-ENTITY-SENSOR-MIB on my server that was originating the snmpwalk.)
