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

Subject: Re: Collisions
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.
