Excessive Multicasts

Counter

Excessive Multicasts is a counter that can be used to monitor fluctuations in the number of multicast messages 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 multicasts. An alarm event can also be generated based on an absolute number of multicasts over time.

The default is 400 multicast packets per second on a 100MB network.
