Security Commands 1044
Either the level or the rate threshold may be configured, but not both.
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

configuration to the default.
