storm-control
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.
