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

How to Configure QoS Congestion Management on Cisco IOS XR Software

Restrictions

The amount of bandwidth configured should be large enough to also accommodate Layer 2 overhead.

A policy map can have all class bandwidths specified in kilobits per second or percentages but not a mixture of both in the same class.

The bandwidth command is supported only on policies configured on outgoing interfaces.

SUMMARY STEPS

1.configure

2.policy-map policy-name

3.class class-name

4.bandwidth {kbps percent value}

5.bandwidth remaining percent value

6.exit

7.class class-name

8.bandwidth {kbps percent value}

9.bandwidth remaining percent value

10.exit

11.exit

12.interface type instance

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

14.end or commit

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