Storm control commands can be used to configure broadcast, multicast,

and unknown unicast storm control thresholds. Traffic storms may occur

when a device on your network is malfunctioning, or if application

programs are not well designed or properly configured. If there is too much

traffic on your network, performance can be severely degraded or

everything can come to complete halt.

You can protect your network from traffic storms by setting a threshold for

broadcast, multicast or unknown unicast traffic. Any packets exceeding the

specified threshold will then be dropped.
