5.2.13.21. storm-control unicast action
This command configures the unicast storm recovery action to either shutdown or trap for all interfaces (Global
Config mode) or one or more interfaces (Interface Config mode).
If configured to shutdown, the interface that receives unicast packets at a rate above the threshold is
diagnostically disabled. The option trap sends trap messages approximately every 30 seconds until unicast storm
control recovers.

(GlobalConfig mode) or one or more interfaces (Interface Config mode).

Interface Config
5.2.13.23. storm-control unicast level
This command configures the unicast storm recovery threshold for all interfaces (Global Config mode) or one or
more interfaces (Interface Config mode) as a percentage of link speed, and enables unicast storm recovery.
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.This command also
enables unicast storm recovery mode for an interface.
