After you have created an output policy map, you attach it to an egress port. See the
Policy to an Interface" section on page
Use the no form of the appropriate command to delete an existing policy map or class map or to cancel
the priority queuing or policing for the priority class or the bandwidth setting for the other classes.
This example shows how to use the priority with police commands to configure out-class1 as the
priority queue, with traffic going to the queue limited to 20000000 bps so that the priority queue never
uses more than that. Traffic above that rate is dropped. The other traffic queues are configured as in the
previous example.
Switch(config)# policy-map policy1
Switch(config-pmap)# class out-class1
Switch(config-pmap-c)# priority
Switch(config-pmap-c)# police 200000000
Switch(config-pmap-c)# exit
Switch(config-pmap)# class out-class2
Switch(config-pmap-c)# bandwidth percent 50
Switch(config-pmap-c)# exit
Switch(config-pmap)# class out-class3
Switch(config-pmap-c)# bandwidth percent 20
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# service-policy output policy1
Switch(config-if)# exit

Configuring Output Policy Maps with Weighted Tail Drop

Weighted tail drop (WTD) adjusts the queue size (buffer size) associated with a traffic class. You
configure WTD by using the queue-limit policy-map class configuration command.

33-62
Purpose
Set output bandwidth limits for the policy-map class in kilobits
per second (the range is 64 to 1000000) or a percentage of the
total bandwidth (the range is 1 to 100 percent) or specify the
average class-based shaping rate in bits per second (the range is
64000 to 1000000000).
Return to policy-map configuration mode.
Return to global configuration mode.
Enter interface configuration mode for the interface to which you
want to attach the policy.
Attach the policy map (created in Step 3) to the egress interface.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
