Chapter 26 Configuring Port-Based Traffic Control

Configuring Storm Control

	Command	Purpose
Step 3
	storm-control {broadcast multicast	Configure broadcast, multicast, or unicast storm control. By
	unicast} level {level [level-low] bps bps	default, storm control is disabled.
	[bps-low] pps pps [pps-low]}	The keywords have these meanings:
		• For level, specify the rising threshold level for broadcast,
		multicast, or unicast traffic as a percentage (up to two decimal
		places) of the bandwidth. The port blocks traffic when the
		rising threshold is reached. The range is 0.00 to 100.00.
		• (Optional) For level-low, specify the falling threshold level as
		a percentage (up to two decimal places) of the bandwidth. This
		value must be less than or equal to the rising suppression
		value. The port forwards traffic when traffic drops below this
		level. If you do not configure a falling suppression level, it is
		set to the rising suppression level. The range is 0.00 to 100.00.
		If you set the threshold to the maximum value (100 percent),
		no limit is placed on the traffic. If you set the threshold to 0.0,
		all broadcast, multicast, and unicast traffic on that port is
		blocked.
		• For bps bps, specify the rising threshold level for broadcast,
		multicast, or unicast traffic in bits per second (up to one
		decimal place). The port blocks traffic when the rising
		threshold is reached. The range is 0.0 to 10000000000.0.
		• (Optional) For bps-low, specify the falling threshold level in
		bits per second (up to one decimal place). It can be less than or
		equal to the rising threshold level. The port forwards traffic
		when traffic drops below this level. The range is 0.0 to
		10000000000.0.
		• For pps pps, specify the rising threshold level for broadcast,
		multicast, or unicast traffic in packets per second (up to one
		decimal place). The port blocks traffic when the rising
		threshold is reached. The range is 0.0 to 10000000000.0.
		• (Optional) For pps-low, specify the falling threshold level in
		packets per second (up to one decimal place). It can be less
		than or equal to the rising threshold level. The port forwards
		traffic when traffic drops below this level. The range is 0.0 to
		10000000000.0.
		For BPS and PPS settings, you can use metric suffixes such as k,
		m, and g for large number thresholds.
Step 4
	storm-control action {shutdown trap}	Specify the action to be taken when a storm is detected. The default
		is to filter out the traffic and not to send traps.
		• Select the shutdown keyword to error-disable the port during
		a storm.
		• Select the trap keyword to generate an SNMP trap when a
		storm is detected.
Step 5
	end	Return to privileged EXEC mode.
