Creating Fair Queues at Two Levels of Hierarchy

To create fair queues at two levels of hierarchy, enter the following commands beginning in global
configuration mode:
Use the following commands to configure both the child and parent policies. Configure the bottom-level
Note
child policy first and then the top-level parent policy. For information about additional actions you can
specify in child policies, see the
Command
Step 1
Router(config)# policy-map
policy-map-name
Step 2
Router(config-pmap)# class class-map-name
OL-7433-09
Define child policies before you define the parent policy. For example, for a nested policy, define
the bottom-level policy and then the top-level parent policy. For a three-level policy, define the
bottom-level policy, the middle-level policy, and then the top-level parent policy.
Do not specify the input or output keyword in the service-policy command when configuring a
child policy within another child policy or within a parent policy.
Do not configure a child policy in a traffic class of a bottom-level policy. Configure child policies
only in middle-level and top-level parent policies.
