THanx for the info.

I found a private mib that may be of use. locIfInPktsSec and
locIfOutPktsSec.
So if I understand you correctly, if I want to monitor collisions on the
Cisco's Ethernet interface i should just convert the locIfCollisions to
Pkts/sec and then divide the result with locIfOutPktsSec?

To get a percentage, you need to divide by the number of packets.  I don't
know if there is a private Cisco MIB for that or not.  We usually use the
sum of the public MIBs if InUcastPkts, ifInNUcastPkts, ifOutUcastPkts and
ifOutNUcastPkts.  Maybe you could just use the two ifOut* MIBs since
collisions only occur on transmitted packets.

        Hi!

        If I want to find out the collision % on a cisco router what packet
counter
        should i use?

        Since the locIfCollisions in the cisco-MIB is messured in total
number of
        packets, *Octets won't be correct right? I can't seem to find a
MIB-variable
        that counts the total number of packets (like etherStatsPkts from
the
        RMON-MIB). I assume, that is the type of counter I need.
