on a port or to specify the action taken when a storm occurs on a port, use the storm-control command
in interface configuration mode. To disable storm control for broadcast, multicast, or unicast traffic or
to disable the specified storm-control action, use the no form of this command.
storm-control {{broadcast | multicast | unicast} {level level | level pps rate} [action [shutdown
| trap]]}
no storm-control {{broadcast | multicast | unicast} {level level | level pps rate} [action
[shutdown | trap]]}

Syntax Description

Command History
action Action taken when a storm occurs on an interface. By default, packets
are dropped when a storm occurs on a interface. Optionally,
specifying:
• shutdown—Disables the interface if a traffic storm occurs.
• trap—Sends an SNMP trap if a traffic storm occurs.
broadcast Enables broadcast address storm control on the interface.
multicast Enables multicast address storm control on the interface.
unicast Enables unicast address storm control on the interface.
level level Sets the rising suppression level as a percent of total bandwidth, up
to two decimal places. Valid values are from 0 (port forwards no
traffic) to 100 (no storm control active). When the value specified for
level is reached, the flooding of storm packets is blocked.
level pps rate Defines the rising suppression level in PPS. Valid values are 0 (port
forwards no traffic) to 42949672950.
