Chapter 24 Configuring QoS

Configuring Quality of Service (QoS)

Step 5 Use the match command to specify the match criteria for the class map. You can define a variety of match criteria including CoS, DSCP, MPLS Exp, or QoS group value.

Router(config-cmap)# match qos-group 7

Note Class-default queue matches packets with qos-group 0.

Step 6 Exit configuration mode.

Router(config-cmap)# end

Creating a Policy Map for Applying a QoS Feature to Network Traffic

A policy map allows you to apply a QoS feature to network traffic based on the traffic classification. Complete the following steps to create and configure a policy map that uses an existing class map.

Step 1 Enter enable mode.

Router> enable

Step 2 Enter the password.

Password: password

When the prompt changes to Router, you have entered enable mode.

Step 3 Enter global configuration mode.

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Step 4 Use the policy-mapcommand to define a new policy map and enter policy map configuration mode.

Router(config)# policy-map policy1

Router(config-pmap)#

Step 5 Use the class command to specify a traffic class to which the policy applies. This command enters policy-map class configuration mode, which allows you to define the treatment for the traffic class.

Router(config-pmap)# class class1

Router(config-pmap-c)#

Use the bandwidth command to specify the bandwidth allocated for a traffic class attached to the policy map. You can define the amount of bandwidth in kbps, a percentage of bandwidth, or an absolute amount of bandwidth. This step is optional.

Note GigabitEthernet interfaces only support bandwidth defined as a percentage or remaining percent.

Router(config-pmap-c)# bandwidth percent 50

Step 6 Exit configuration mode.

Router(config-cmap)# end
