The Storm Control feature protects against this condition. The switch software provides broadcast, multicast, and unicast storm recovery for individual interfaces. Unicast Storm Control protects against traffic whose MAC addresses are not known by the system. For broadcast, multicast, and unicast storm control, if the rate of traffic ingressing on an interface increases beyond the configured threshold for that type, the traffic is dropped. To configure storm control, you will enable the feature for all interfaces or for individual interfaces, and you will set the threshold (storm control level) beyond which the broadcast, multicast, or unicast traffic will be dropped.

Example #1: Enter a Description for a Port
This example specifies the name “Test” for port 1/g17:
console#configure
console(config)#interface ethernet 1/g17

Storm Control
A traffic storm occurs when incoming packets flood the LAN resulting in network performance
degradation. The Storm Control feature protects against this condition.
The switch software provides broadcast, multicast, and unicast storm recovery for individual interfaces.
Unicast Storm Control protects against traffic whose MAC addresses are not known by the system.
For broadcast, multicast, and unicast storm control, if the rate of traffic ingressing on an interface
increases beyond the configured threshold for that type, the traffic is dropped.
To configure storm control, you will enable the feature for all interfaces or for individual interfaces, and
you will set the threshold (storm control level) beyond which the broadcast, multicast, or unicast traffic
will be dropped.
