Configuring QoS
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
This example configures classes for output service policies with three classes of service: gold, silver, and
bronze. The gold class is configured to match the marked value in the input service policy. 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-out
Switch(config-cmap)# match ip dscp af43
Switch(config-cmap)# exit
Switch(config)# class-map match-any silver-out
Switch(config-cmap)# match ip dscp af21
Switch(config-cmap)# exit
Switch(config)# class-map match-any bronze-out
Switch(config-cmap)# match ip dscp af31
Switch(config-cmap)# exit
This example configures one output service policy to be applied to both Gigabit Ethernet NNIs,
providing priority with rate-limiting to the gold class, class-based shaping for the silver class, and a
minimum bandwidth guarantee of 10 percent to the bronze class.
Switch(config)# policy-map output-g1-2
Switch(config-pmap)# class gold-out
Switch(config-pmap-c)# priority
Switch(config-pmap-c)# police 50000000
Switch(config-pmap-c)# exit
Switch(config-pmap)# class silver-out
Switch(config-pmap-c)# shape average 200000
Switch(config-pmap-c)# exit
Switch(config-pmap)# class bronze-out
Switch(config-pmap-c)# bandwidth percent 10
Switch(config-pmap-c)# exit
