MC3G60 System Uptime with SNMP

Hi All,

I would like to monitor our MC3G60 linecards on our UBR10k systems by SNMP,

and found this OID:

cefcModuleUpTime -

1.3.6.1.4.1.9.9.117.1.2.1.1.8

(ciscoEntityFRUControlMIB)

when I try to walk this OID, the system returns a 'No Such Instance currently exists at this OID'

Is this the correct OID to fetch the uptimes for our linecards ?

UBR is running on 12.2(33)SCG4

Dag Joost,

I assume you can get other OID's from this device without a problem?

What you must understand is that there is an OID and an instance. To obtain the instance(s) you should walk the OID.  

So under 1.3.6.1.4.1.9.9.117.1.2.1.1.8 you may find that there are 4 instances for your card. I make up something here to paint you the picture:

1.3.6.1.4.1.9.9.117.1.2.1.1.8.1

1.3.6.1.4.1.9.9.117.1.2.1.1.8.123

1.3.6.1.4.1.9.9.117.1.2.1.1.8.124

1.3.6.1.4.1.9.9.117.1.2.1.1.8.1001

These 4 entries are then for you to collect to have the uptime of each card.

Now if the device says 1.3.6.1.4.1.9.9.117.1.2.1.1.8 does not exist when you try to do a snmpwalk, it could be a number of things.

  • A SNMP view on the device could block at part of the MIB.( Chec kconfig e.g. exclude cisco 1.3.6.1.4.1.9.)
  • There could be a problem with the device agent (on device console try  debug snmp [packets|event|all].  Compare with other devices )
  • And last but not least, cisco has (like other vendors) the habit of implementing mibs partialy   :-|  It is possible that a documented OID simply does not work (yet). (sometimes the releasenotes shed some light on this)

Cheers,

Michel
