When the Multicast threshold is exceeded Multicast, Broadcast, and
Unicat packets are dropped. The only thing that gets through are
Spanning-tree Packets. When the Unicast and Broadcast thresholds are
exceeded only that particular type of traffic is dropped. Multicast is
the only one to watch out for.

The important part of it is:
"Note When the rate of multicast traffic exceeds a set threshold, all
incoming traffic (broadcast, multicast, and unicast) is dropped until
the level drops below the threshold level. Only spanning-tree packets
are forwarded. When broadcast and unicast thresholds are exceeded,
traffic is blocked for only the type of traffic that exceeded the
threshold."

Hello everybody,
When using the storm-control command you can specify a rate limit for
incoming broadcast, multicast and unicast packets.
The Doc CD explains that if some kind of traffic exceeds the threshold,
all
the traffic of this kind will be dropped.
In a workbook i have read that if the multicast threshold is exceeded,
all
traffic of any kind(broadcast, multicast and unicast) will be dropped.
Could somebody tell me which one is correct? Who should i trust on?
Thanks
