Enter the storm-control level command to enable traffic storm control on the interface, configure the traffic storm-control level, and apply the traffic storm-control level to all traffic storm-control modes that are enabled on the interface.
The period (.) is required when you enter the fractional-suppression level.
The suppression level is a percentage of the total bandwidth. A threshold value of 100 percent means that no limit is placed on traffic. A threshold value of 0 or 0.0 (fractional) percent means that all specified traffic is blocked on a port.
Use the show interfaces counters storm-control command to display the discard count.
