Usage guidelines

You can nest a QoS policy in a traffic behavior to reclassify traffic of the class associated with the

behavior and take actions defined in the policy on the reclassified traffic.

After you nest a child policy in a behavior of a parent policy, the system does the following:

• Performs the associated behavior defined in the parent policy for a class of traffic.

• Uses the child policy to further classify the class of traffic and perform the behaviors defined in the

child policy.

When you nest QoS policies, follow these guidelines:

• A parent policy can nest up to two layers of child policies. This child policy cannot be the parent

policy itself.

• You can nest only one child policy at one layer of a behavior.

• To configure CBQ in the child policy successfully, configure GTS in the parent policy. Make sure the

configured GTS bandwidth is greater than CBQ bandwidth configured in the child policy.

• If GTS bandwidth is set in percentage in the parent policy, you must set CBQ bandwidth in

percentage in the child policy. If GTS bandwidth is set as an absolute value in the parent policy, you

can set CBQ bandwidth in percentage or as an absolute value in the child policy.

• A child policy cannot contain GTS actions.

• Policy nesting is available for IPv4 and IPv6 packets.

• To delete the child policy after you apply the parent policy to an interface, first remove the child

policy from the parent policy.
