Command History

Release Modification

This command was introduced.

Usage Guidelines

Storm control can act only on ingress traffic and not egress traffic.

If an interface configured with storm-control is part of the port-channel, storm-control is not active on the port-channel and only acts on the interface.

Storm control only drops traffic that is above the suppression level.

Examples

The following is an example of storm control configuration:


nfvis(config-switch)# interface gigabitEthernet 1/0
nfvis(config-switch-if)# storm-control broadcast level 20
nfvis(config-switch-if)# commit
nfvis(config-switch-if)# end
