How to Configure QoS Congestion Management on Cisco IOS XR Software

	Command or Action	Purpose
Step 4
	police {cir {kbps percent percent}} [bc	Configures traffic policing.
	conform-burst] [be peak-burst][conform-action	The traffic policing feature works with a token bucket
	action [exceed-action action] [pir kbps]
	[violate-action action]	algorithm.
		The action argument is specified by one of the following
	Example:	keywords:
	RP/0/RP0/CPU0:router(config-pmap-c)# police cir	• drop—Drops the packet.
	250 conform-action set mpls experimental
	topmost 3 exceed-action set mpls experimental	• set dscp dscp-value—Sets the DSCP value and sends
	topmost 4	the packet.
		• set prec new-precedence—Sets the IP precedence and
		sends the packet.
		• set mpls experimental topmost—Sets the EXP value
		on the MPLS packet topmost label
		• set discard class—Sets the discard class and QoS
		group identifiers on IP Version 4 (IPv4) or
		Multiprotocol Label Switching (MPLS) packets.
		Note The pir and violate-actionkeywords are not
		supported on the Cisco XR 12000 Series Router.
Step 5
	exit	Returns the router to policy map configuration mode.
	Example:
	RP/0/RP0/CPU0:router(config-pmap-c)# exit
Step 6
	exit	Returns the router to global configuration mode.
	Example:
	RP/0/RP0/CPU0:router(config-pmap)# exit
Step 7
	interface type instance	Enters configuration mode and configures an interface.
	Example:
	RP/0/RP0/CPU0:router(config)# interface POS
	0/5/0/0
Step 8
	service-policy {input output} policy-map	Attaches a policy map to an input or output interface to be
		used as the service policy for that interface.
	Example:	• The traffic policy evaluates all traffic leaving that
	RP/0/RP0/CPU0:router(config-if) service-policy	interface.
	input policy1
