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.
