Storm Control
A broadcast storm is the result of an excessive number of broadcast messages
simultaneously transmitted across a network by a single port. Forwarded message
responses can overload network resources and/or cause the network to time out.

responses can overload network resources and/or cause the network to time out.
The switch measures the incoming broadcast/multicast/unknown unicast packet rate per port
and discards packets when the rate exceeds the defined value. Storm control is enabled per
interface, by defining the packet type and the rate at which the packets are transmitted.
