Configuring QoS
Configuration Examples for Policy Maps
These steps activate all Gigabit Ethernet ports:
Switch(config)#
interface range GigabitEthernet1/17-18
Switch(config-if-range)# no shutdown
Switch(config-if-range)# exit
Modifying Output Policies and Adding or Deleting a Class
This section provides examples of updating an existing set of output policy maps to add or delete entire classes. The
modification in the output policy map might be required due to a change in the service provisioning requirements or a
change in the input service policy. To make this change, you must shut down all active ports on the switch. For this kind
of update to any output policy map, all customers could potentially be affected. To avoid this, we recommend that you
consider possible future upgrades when you configure classes in output service policies.
In the initial configuration, Gigabit Ethernet ports 1 and 2 are NNIs and are enabled by default.
This is the overall sequence of configuration:

Shut down all active ports.

Detach the output policies from all Ethernet ports.

Delete the class.

Reattach the output policies to the Ethernet ports.

Take the Ethernet ports out of the shutdown state.
These steps shut down all active and applicable Ethernet ports:
Switch(config)# interface range GigabitEthernet1/17-18
Switch(config-if-range)# shutdown
Switch(config-if-range)# exit
These steps detach all output policies from the affected Ethernet ports:
Switch(config)# interface range GigabitEthernet1/17-18
Switch(config-if-range)# no service-policy output output-g1-2
Switch(config-if-range)# exit
These steps delete a class from all output policy maps and input policy maps; the input policy can be left attached or
can be detached:
Switch(config)#
policy-map output1-8
Switch(config-pmap)# no class bronze-out
Switch(config-pmap-c)# exit
Switch(config)#
policy-map output9-12
Switch(config-pmap)# no class bronze-out
Switch(config-pmap-c)# exit
Switch(config)#
policy-map output-g1-2
Switch(config-pmap)# no class bronze-out
Switch(config-pmap-c)# exit
Switch(config)#
policy-map input-all
Switch(config-pmap)# no class bronze-in
Switch(config-pmap-c)# exit
These steps reattach all policies to the Ethernet ports:
Switch(config)#
interface range GigabitEthernet1/17-18
Switch(config-if-range)# service-policy output output9-12
