New to MIB's

Unanswered Question
Sep 9th, 2008

Is there anywhere where I can find what MIB number means what?

I am getting this information from our switch and don't know what I should look at....I checked the switch via show tech and did not see anything wrong

MIB for this device, a 6 is "

enterprises.cisco.ciscoMgmt.ciscoEnvMonMIB.ciscoEnvMonObjects.ciscoEnvMo

nFanStatusTable.ciscoEnvMonFanStatusEntry.ciscoEnvMonFanState.202 =

notFunctioning(6)

Does anyone no where I can get information on this?

Thanks,

Mike

Thanks for the link it was great. I thought it was pretty evident as to what it was until I looked at the fans, all working, and then reviewed the output of show tech and saw nothing failed, so I thought it might be something else as I am pretty new to understanding MIB's and what goes to what.

Any ideas what could be causing this false reading?

What does "show env status" say about the fan(s)?

It could be akin to link flapping. It may be back to working for now as a one-time anomaly, or a precursor to eventual permanent failure. I'd open a case with TAC so the next time it happens, there's proof of prior occurence to request an RMA.

Also....it is still reporting it as bad now and I see nothing wrong.

ciscoEnvMonFanStatusEntry.ciscoEnvMonFanStatusDescr.11 = chassis-1

Chassis Fan Tray 1

ciscoEnvMonFanStatusEntry.ciscoEnvMonFanStatusDescr.12 = chassis-1 Power

Supply 1 Fan

ciscoEnvMonFanStatusEntry.ciscoEnvMonFanStatusDescr.13 = chassis-1 Power

Supply 2 Fan

ciscoEnvMonFanStatusEntry.ciscoEnvMonFanStatusDescr.201 = chassis-2

Chassis Fan Tray 1

ciscoEnvMonFanStatusEntry.ciscoEnvMonFanStatusDescr.202 = chassis-2

Power Supply 1 Fan

ciscoEnvMonFanStatusEntry.ciscoEnvMonFanStatusDescr.203 = chassis-2

Power Supply 2 Fan

ciscoEnvMonFanStatusEntry.ciscoEnvMonFanState.11 = normal(1)

ciscoEnvMonFanStatusEntry.ciscoEnvMonFanState.12 = normal(1)

ciscoEnvMonFanStatusEntry.ciscoEnvMonFanState.13 = normal(1)

ciscoEnvMonFanStatusEntry.ciscoEnvMonFanState.201 = normal(1)

ciscoEnvMonFanStatusEntry.ciscoEnvMonFanState.202 = notFunctioning(6)

ciscoEnvMonFanStatusEntry.ciscoEnvMonFanState.203 = notFunctioning(6)

But I look at the Power supply fans and they are working.

We have found the issue stems from IOS bug CSCso57334:

Symptom:
