Either the trap action or the shutdown action may be specified, but not both.
The trap action issues a log message and a trap when the configured threshold
is exceeded. Traffic exceeding the threshold is dropped.
The shutdown action shuts down the interface, puts the interface into the D-
disable state, issues a log message (WARNING) and a trap. The operator may
bring the port back into service using the no shutdown command.
Use the show storm-control action and show storm-control all commands to
display the storm control settings.
Example
The following example configures any port to drop excess broadcast traffic
and issue a log and trap if the received broadcast traffic exceeds 10% of link
bandwidth:
console(config)#interface range gi1/0/1-24
console(config-if)#storm-control broadcast level 10
console(config-if)#storm-control broadcast action trap
console(config-if)#exit
storm-control multicast
Use the storm-control multicast command in Interface Configuration mode
to enable multicast storm storm control for an interface.
Use the no form of the command to disable storm-control in order to return
the configuration to the default.
