Christian,

Sorry for the delay in replying, but it appears that no one provided you
with the RMON MIB for collisions.  If you have a device/probe with RMON
capabilities, then it is another possible source of monitoring collisions.
It is in the RMON etherStats table, which is at

        .1.3.6.1.2.1.16.1.1.1.13

        Collision counter MIB variables are in the Ethernet MIB and in
various
        vendor enterprise MIBs.

        The snmp_mibs directory on your NV system should contain the
Ethernet MIB
        either in its January 1993 version as RFC1398, or a later version. (
        RFC1398 has subsequently been updated and made obsolete by RFC1623,
then
        RFC1643, then, for SMI v2, RFC1650, RFC2358, and finally RFC2665. I
suggest
        you load the latest one of these that you can find on your system.)

        However, even RFC1398 has a dot3StatsTable which has (among other
counters):
        dot3StatsSingleCollisionFrames
        dot3StatsMultipleCollisionFrames
        dot3StatsLateCollisions
        dot3StatsExcessiveCollisions

        Various vendor enterprise MIBs also have collision counters, so I
would
        also look in the appropriate enterprise MIBs for your
hub/switch/routers,
        try Gets on both sets of variables and compare them.

        Finally, I would, if possible, put a protocol analyser on for a
short
        period to verify that correct counts are being reported in the SNMP
MIB
        variables.
