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

 

 

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
