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

How to Configure QoS Congestion Management on Cisco IOS XR Software

Shaping performed on incoming interfaces is done at the Layer 3 level and does not include the Layer 2 header in the rate calculation.

Restrictions

The bandwidth, priority, and shape average commands should not be configured together in the same class.

SUMMARY STEPS

1.configure

2.policy-map policy-name

3.class class-name

4.shape average {percent value kbps}

5.exit

6.exit

7.interface type instance

8.service-policy {input output} policy-map

9.end or commit

10.show policy-map interface type instance [input output]

DETAILED STEPS

	Command or Action	Purpose
Step 1
	configure	Enters global configuration mode.
	Example:
	RP/0/RP0/CPU0:router# configure
Step 2
	policy-map policy-name	Enters policy map configuration mode.
		• Creates or modifies a policy map that can be attached to
	Example:	one or more interfaces to specify a service policy.
	RP/0/RP0/CPU0:router(config)# policy-map
	policy1
Step 3
	class class-name	Enters policy map class configuration mode.
		• Specifies the name of the class whose policy you want
	Example:	to create or change.
	RP/0/RP0/CPU0:router(config-pmap)# class class1
Step 4
	shape average {percent value kbps}	Shapes traffic to the indicated bit rate according to average
		rate shaping in kilobits or the interface bandwidth in
	Example:	percentage.
	RP/0/RP0/CPU0:router(config-pmap-c)# shape
	average percent 50
