storm-control
If you configure the action to be taken as shutdown (the port is error-disabled during a storm) when a
packet storm is detected, you must use the no shutdown interface configuration command to bring the
interface out of this state. If you do not specify the shutdown action, specify the action as trap (the
switch generates a trap when a storm is detected).
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.
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.
Examples
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.
