storm-control

When a storm occurs and the action is to filter traffic, if the falling suppression level is not specified, the

switch blocks all traffic until the traffic rate drops below the rising suppression level. If the falling

suppression level is specified, the switch blocks traffic until the traffic rate drops below this level.

Storm control is supported on physical interfaces. You can also configure storm control on an

EtherChannel. When storm control is configured on an EtherChannel, the storm control settings

propagate to the EtherChannel physical interfaces.

When a broadcast storm occurs and the action is to filter traffic, the switch blocks only broadcast traffic.

For more information, see the software configuration guide for this release.

This example shows how to enable broadcast storm control with a 75.5-percent rising suppression level:

Switch(config-if)# storm-control broadcast level 75.5

This example shows how to enable unicast storm control on a port with a 87-percent rising suppression

level and a 65-percent falling suppression level:

Switch(config-if)# storm-control unicast level 87 65

This example shows how to enable multicast storm control on a port with a 2000-packets-per-second

rising suppression level and a 1000-packets-per-second falling suppression level:

Switch(config-if)# storm-control multicast level pps 2k 1k

This example shows how to enable the shutdown action on a port:

Switch(config-if)# storm-control action shutdown

You can verify your settings by entering the show storm-control privileged EXEC command.
