Purpose
Enter global configuration mode.
Enter interface configuration mode, and enter the port to configure.
Configure broadcast, multicast, or unicast storm control.
Specify the rising threshold level for either broadcast, multicast, or
unicast traffic. The storm control action occurs when traffic
utilization reaches this level.
(Optional) Specify the falling threshold level. The normal
transmission restarts (if the action is filtering) when traffic drops
below this level.
Specify the action to be taken when a storm is detected.
The default is to filter out the traffic and not to send out traps.
Select the shutdown keyword to error-disable the port during a
storm.
Select the trap keyword to generate an SNMP trap when a storm is
detected.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
