Information About Traffic Storm Control

A traffic storm occurs when packets flood the LAN, creating excessive traffic and degrading network
performance. You can use the traffic storm control feature to prevent disruptions on Ethernet interfaces by a
broadcast, multicast, or unknown unicast traffic storm.
Traffic storm control (also called traffic suppression) allows you to monitor the levels of the incoming broadcast,
multicast, and unicast traffic over a 10-microsecond interval. During this interval, the traffic level, which is
a percentage of the total available bandwidth of the port, is compared with the traffic storm control level that
you configured. When the ingress traffic reaches the traffic storm control level that is configured on the port,
traffic storm control drops the traffic until the interval ends.
