Configuring QoS
Configuration Examples for Policy Maps
QoS Configuration for Customer A
This section provides examples of the initial configuration and activation of QoS policies for a customer switch. Input and
output QoS service policies are configured based on the requirements and attached to relevant ports.
In the initial configuration for Customer A, Gigabit Ethernet ports 1 and 2 are network node interfaces (NNIs) and are
enabled by default.
This is the overall sequence for initial configuration:
 Configure classes and policies.
 Shut down all active ports.
 Attach policies to ports to be activated.
 Take the ports out of the shut-down state.
 Leave unused ports shut down.
Note these restrictions for configuring output policies:
 You can define up to three classes in the output policy map.
 The defined classes must be the same as other output policy maps.
 The number of defined classes in each output policy map must be same.
 You must assign an action to each class; that is, there can be no empty class.
 Each class configuration must be based on the classification/marking done in the input policy-map.
This example configures classes for input service policies and defines three classes of service: gold, silver, and bronze.
Because a match-all classification (the default) can have only single classification criterion, the match-any classification
is used so that you can add classification criteria in the future.
Switch# config terminal
Switch(config)# class-map match-any gold-in
Switch(config-cmap)# match ip dscp af11
Switch(config-cmap)# exit
Switch(config)# class-map match-any silver-in
Switch(config-cmap)# match ip dscp af21
Switch(config-cmap)# exit
Switch(config)# class-map match-any bronze-in
Switch(config-cmap)# match ip dscp af31
Switch(config-cmap)# exit
This example shows how to configure an input policy map that marks the gold class and polices the silver class to
50 Mb/s and the bronze class to 20 Mb/s.
Switch(config)# policy-map input-all
Switch(config-pmap)# class gold-in
Switch(config-pmap-c)# set ip dscp af43
Switch(config-pmap-c)# exit
Switch(config-pmap)# class silver-in
Switch(config-pmap-c)# police 50000000
Switch(config-pmap)# class bronze-in
Switch(config-pmap-c)# police 20000000
Switch(config-pmap-c)# exit
