OIDs to Monitor In/Out Bits Per Sec?

Unanswered Question
Feb 21st, 2007


I am trying to setup a new MRTG NMS to monitor In & Out Bps on various Cisco routers. I have found two OIDs for this:



My question is, since Cisco have indicated this is an "old" MIB, provided the NMS has up-to-date MIBs will it recognize these OIDs or must I load in the specific "old" MIB following the specific ordering by Cisco?



I have this problem too.

You will need to load the OLD-CISCO-INTERFACES-MIB into MRTG to have it recognize these objects. However, these objects are deprecated; and while they should work, there may be bugs. You should instead consider using the ifInOctets and ifOutOctets objects from the IF-MIB, and do the conversion to bits by multiplying by eight.

Additionally, if the interfaces in which you are interested are high-speed interfaces, you may find these bit counters roll over too quickly. If you then switch to using the ifHCInOctets and ifHCOutOctets from the IF-MIB (ifXTable). These are 64-bit counters, and will provide more accurate measurements for high-speed interfaces.

thanks for your response. I knew there had to be some sort of work around for a more updated MIB.
