Re: Storm control

I have seen this worded quite a few ways, every time I read it it looks or sounds a little different:

"Storm control (or traffic suppression) monitors incoming traffic statistics over a time period and compares the measurement with a predefined suppression level threshold."

"Storm control (or traffic suppression) monitors packets passing from an interface to the switching bus and determines if the packet is unicast, multicast, or broadcast. The switch counts the number of packets of a specified type received within the 1-second time interval and compares the measurement with a predefined suppression-level threshold."

"Per-port broadcast, multicast, and unicast storm control prevents faulty end stations from degrading overall systems performance."

I would interpret the first two as incoming, the third your guess is as good as mine :)

When configuring this feature remember one of the 3560 12.2(25)SE changes with the "level" options were modified for bps.

egress or both direction....
Thanks,
