Syntax Description
Specifies the action taken when a storm occurs on a port. The default action is to filter
traffic and to not send an Simple Network Management Protocol (SNMP) trap. action
Disables the port during a storm. shutdown
Sends an SNMP trap when a storm occurs. trap
Enables broadcast storm control on the interface. broadcast
Enables multicast storm control on the interface. multicast
Enables unicast storm control on the interface.
unicast
Specifies the rising and falling suppression levels as a percentage of total bandwidth
of the port.
level
Rising suppression level, up to two decimal places. The range is 0.00 to 100.00. Block
the flooding of storm packets when the value specified for level is reached. level
(Optional) Falling suppression level, up to two decimal places. The range is 0.00 to
100.00. This value must be less than or equal to the rising suppression value. If you
do not configure a falling suppression level, it is set to the rising suppression level. level-low
Specifies the rising and falling suppression levels as a rate in bits per second at which
traffic is received on the port. level bps
Rising suppression level, up to 1 decimal place. The range is 0.0 to 10000000000.0.
Block the flooding of storm packets when the value specified for bps is reached.
You can use metric suffixes such as k, m, and g for large number thresholds.
