User Guidelines
Broadcast storm control can only be enabled on Ethernet interfaces. It cannot
be configured on port channels.
Setting the level, rate or action enables broadcast storm control. When
enabled, broadcast storm control can issue a trap and drop traffic in excess of
the configured rate (level) or shut down the port if the rate is exceeded.
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.
