Configuration Examples for QoS
Switch(config-if)# exit
Switch(config)# exit
Switch#
This example shows that when a child-level policy map is attached below a class, an action must be specified
for the class:
Switch(config)# policy-map vlan-plcmap
Switch(config-pmap)# class cm-5
Switch(config-pmap-c)# set dscp 7
Switch(config-pmap-c)# service-policy port-plcmap-1
This example shows how to configure a class map to match IP DSCP and IPv6:
Switch(config)# class-map cm-1
Switch(config-cmap)# match ip dscp 10
Switch(config-cmap)# match protocol ipv6
Switch(config-cmap)# exit
Switch(config)# class-map cm-2
Switch(config-cmap)# match ip dscp 20
Switch(config-cmap)# match protocol ip
Switch(config-cmap)# exit
Switch(config)# policy-map pm1
Switch(config-pmap)# class cm-1
Switch(config-pmap-c)# set dscp 4
Switch(config-pmap-c)# exit
Switch(config-pmap)# class cm-2
Switch(config-pmap-c)# set dscp 6
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
Switch(config)# interface G1/0/1
Switch(config-if)# service-policy input pm1
This example shows how to configure default traffic class to a policy map:
Switch# configure terminal
Switch(config)# class-map cm-3
Switch(config-cmap)# match ip dscp 30
Switch(config-cmap)# match protocol ipv6
Switch(config-cmap)# exit
Switch(config)# class-map cm-4
Switch(config-cmap)# match ip dscp 40
Switch(config-cmap)# match protocol ip
Switch(config-cmap)# exit
Switch(config)# policy-map pm3
Switch(config-pmap)# class class-default
Switch(config-pmap)# set dscp 10
Switch(config-pmap-c)# exit
Switch(config-pmap)# class cm-3
Switch(config-pmap-c) set dscp 4
Switch(config-pmap-c)# exit
Switch(config-pmap)# class cm-4
Switch(config-pmap-c)# trust cos
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
This example shows how the default traffic class is automatically placed at the end of policy-map pm3 even
though class-default was configured first:
Switch# show policy-map pm3
Policy Map pm3
Class cm-3
set dscp 4
Class cm-4
trust cos
Class class-default
