Excessive Collisions
Counter
Excessive Collisions is a counter that can be used to monitor fluctuations in the
number of collisions or the absolute number of collisions over a period of time per
segment. A delta threshold for this counter can be set in Expert Alarms to establish
what is considered excessive collisions. An alarm event can also be generated based
on an absolute number of collisions over time.
The Excessive Collision counter is incremented by counting runt packets and by
counting packets with CRC errors. The Excessive Collisions counter only applies to
Ethernet networks.
