config traffic control

	latter of which will now provide shutdown, recovery and trap
	notification functions for the Switch.
Parameters	<portlist> − Used to specify a range of ports to be configured for
	traffic control. This is specified by listing the lowest switch number
	and the beginning port number on that switch, separated by a
	colon. Then the highest switch number, and the highest port
	number of the range (also separated by a colon) are specified.
	The beginning and end of the port list range are separated by a
	dash. For example, 1:3 specifies switch number 1, port 3. 2:4
	specifies switch number 2, port 4. 1:3-2:4 specifies all of the ports
	between switch 1, port 3 and switch 2, port 4 − in numerical order.
	all − Specifies all ports are to be configured for traffic control on
	the Switch.
	broadcast [enabled disabled] − Enables or disables broadcast
	storm control.
	multicast [enabled disabled] − Enables or disables multicast
	storm control.
	dlf [enabled disabled] − Enables or disables dlf traffic control.
	action – Used to configure the action taken when a storm control
	has been detected on the Switch. The user has two options:
	• drop - Utilizes the hardware Traffic Control mechanism,
	which means the Switch’s hardware will determine the
	Packet Storm based on the Threshold value stated and drop
	packets until the issue is resolved.
	• shutdown - Utilizes the Switch’s software Traffic Control
	mechanism to determine the Packet Storm occurring. Once
	detected, the port will deny all incoming traffic to the port
	except STP BPDU packets, which are essential in keeping
	the Spanning Tree operational on the Switch. If the
	countdown timer has expired and yet the Packet Storm
	continues, the port will be placed in Shutdown Forever mode
	and is no longer operational until the user manually resets
	the port using the config traffic control_recover command.
	Choosing this option obligates the user to configure the
	time_interval field as well, which will provide packet count
	samplings from the Switch’s chip to determine if a Packet
	Storm is occurring.
	threshold <value 0-2047>− The upper threshold at which the
	specified traffic control is switched on. The <value> is the number
	of broadcast/multicast/dlf packets, in kilopackets per second
	(Kpps), received by the Switch that will trigger the storm traffic
	control measures.
	countdown - The countdown timer is set to determine the amount
	of time, in minutes, that the Switch will wait before shutting down
	the port that is experiencing a traffic storm. This parameter is only
	useful for ports configured as shutdown in the action field of this
	command and therefore will not operate for Hardware based
	Traffic Control implementations.
	• value 0 - 0 is the default setting for this field and 0 will
	denote that the port will never shutdown.
	• value 5-30 – Select a time from 5 to 30 minutes that the
	Switch will wait before shutting down. Once this time expires
