storm-control Chapter 2 IE 3000 Switch Cisco IOS Commands 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. Note 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. 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.
