Example
console(config-if-1/0/1)#storm-control multicast
level 5
storm-control unicast
Use the storm-control unicast command in Interface Configuration mode to
enable unknown unicast storm control for an interface. If the mode is
enabled, unicast storm recovery is active, and if the rate of unknown L2
unicast (destination lookup failure) traffic ingressing on an interface increases
beyond the configured threshold, the traffic will be dropped. Therefore, the
rate of unknown unicast traffic will be limited to the configured threshold.
When you use the no storm-control multicast command to "disable" storm-
control after having set the level or rate to a non-default value, that value is
still set but is not active until you re-enable storm-control.
