Chapter 24 Configuring QoS

Extending QoS for MLPPP

 

Command

Purpose

Step 4

 

 

match mpls experimental topmost

Matches the experimental (EXP) value in the topmost label header.

 

number

number—Multiprotocol Label Switching (MPLS) EXP field in the

 

 

 

Example:

topmost label header. Valid values are 0 to 7.

 

Note In this configuration packets with experimental bits of value 5 are

 

Router(config-cmap)# match mpls

 

matched. Repeat this step to configure more values. If any one of

 

experimental topmost 5

 

 

the values is matched, action pertaining to the class-map is

 

 

performed.

Step 5

 

 

exit

Exits class-map configuration mode.

 

Example:

 

 

Router(config-cmap)# exit

 

 

 

 

Configuring Class-map for Matching IP DSCP Value

This classification is required for all the packets flowing without an MPLS header like normal IP packets flowing through an MLPPP Interface.

Complete the following steps to configure class-map for matching IP DSCP Values.

SUMMARY STEPS

1.enable

2.configure terminal

3.class-map match-any class-map-name

4.match ip dscp [dscp-value...dscp-value]

5.exit

DETAILED STEPS

 

 

Command

Purpose

 

Step 1

 

 

 

enable

Enables privileged EXEC mode.

 

 

 

Enter your password if prompted.

 

 

Example:

 

 

 

 

 

 

Router> enable

 

 

 

 

 

Step 2

 

 

 

configure terminal

Enters global configuration mode.

 

 

Example:

 

 

 

 

 

 

Router# configure terminal

 

 

 

 

 

Step 3

 

 

 

class-map match-any class-map-name

Creates a class map to be used for matching packets to a specified class

 

 

 

and to enter QoS class-map configuration mode:

 

 

Example:

class-map-name—Name of the class for the class map. The class

 

 

Router(config)# class-map match-any

name is used for both the class map and to configure a policy for the

 

 

matchdscp

class in the policy map.
