show storm-control
Use the show storm-control user EXEC command to display broadcast, multicast, or unicast storm
control settings on the switch or on the specified interface or to display storm-control history.
show storm-control [interface-id] [broadcast | multicast | unicast] [ | {begin | exclude | include}
expression]
Syntax Description
Command Modes User EXEC
Command History
Usage Guidelines When you enter an interface-id, the storm control thresholds appear for the specified interface.
If you do not enter an interface-id, settings appear for one traffic type for all ports on the switch.
If you do not enter a traffic type, settings appear for broadcast storm control.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output
do not appear, but the lines that contain Output appear.
Examples This is an example of a partial output from the show storm-control command when no keywords are
entered. Because no traffic-type keyword was entered, the broadcast storm control settings appear.
