Explanation:
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 Layer 2 ports
by a broadcast, multicast, or unicast traffic storm on physical interfaces.
Traffic storm control (also called traffic suppression) allows you to monitor the levels of the incoming
broadcast, multicast, and unicast traffic over a 10-millisecond 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.
