Usage Guidelines If the variable interface-id is omitted, the show storm-control command displays storm-control settings
for all ports on the switch.
You can display broadcast, multicast, or unicast packet-storm information by using the corresponding
keyword. When no option is specified, the default is to display broadcast storm-control information.
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.
