Configuring Modular Quality of Service Congestion Management on Cisco IOS XR Software

How to Configure QoS Congestion Management on Cisco IOS XR Software

	Command or Action	Purpose
Step 4
	bandwidth {kbps percent value}	Enters policy map class configuration mode.
		• Specifies the bandwidth allocated for a class belonging
	Example:	to a policy map.
	RP/0/RP0/CPU0:router(config-pmap-c)# bandwidth	• In this example, class class1 is guaranteed 50 percent of
	percent 50
		the interface bandwidth.
Step 5
	bandwidth remaining percent value	Specifies how to allocate leftover bandwidth to various
		classes.
	Example:	• The remaining bandwidth of 40 percent is shared by
	RP/0/RP0/CPU0:router(config-pmap-c)# bandwidth	class class1 and class2 (see Steps 8 and 9) in a 20:80
	remaining percent 20	ratio: class class1 receives 20 percent of the 40 percent,
		and class class2 receives 80 percent of the 40 percent.
Step 6
	exit	Returns the router to policy map configuration mode.
	Example:
	RP/0/RP0/CPU0:router(config-pmap-c)# exit
Step 7
	class class-name	Specifies the name of a different class whose policy you
		want to create or change.
	Example:
	RP/0/RP0/CPU0:router(config-pmap)# class class2
Step 8
	bandwidth {kbps percent value}	Specifies the bandwidth allocated for a class belonging to a
		policy map.
	Example:	• In this example, class class2 is guaranteed 10 percent of
	RP/0/RP0/CPU0:router(config-pmap-c)# bandwidth	the interface bandwidth.
	percent 10
Step 9
	bandwidth remaining percent value	Specifies how to allocate leftover bandwidth to various
		classes.
	Example:	• The remaining bandwidth of 40 percent is shared by
	RP/0/RP0/CPU0:router(config-pmap-c)# bandwidth	class class1 (see Steps 4 and 5) and class2 in a 20:80
	remaining percent 80	ratio: class class1 receives 20 percent of the 40 percent,
		and class class2 receives 80 percent of the 40 percent.
Step 10
	exit	Returns the router to policy map configuration mode.
	Example:
	RP/0/RP0/CPU0:router(config-pmap-c)# exit
Step 11
	exit	Returns the router to global configuration mode.
	Example:
	RP/0/RP0/CPU0:router(config-pmap)# exit
Step 12
	interface type instance	Enters interface configuration mode and configures an
		interface.
	Example:
	RP/0/RP1/CPU0:router(config)# interface POS
	0/2/0/0
