HP MSR2000/3000/4000 Router Series ACL and QoS Command Reference

Parameters
policy-name: Specifies a policy by its name, a string of 1 to 31 characters. If the policy does not exist, it
is automatically created.
Usage guidelines
You can nest a QoS policy in a traffic behavior to re-classify the traffic class associated with the behavior
and take actions defined in the policy on the re-classified traffic.
With policy nesting, you can perform the associated behavior defined in the parent policy for a class of
traffic, and in addition, use the child policy to further classify the class of traffic and perform the
behaviors defined in the child policy.
Follow these guidelines when you nest QoS policies:
• 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 in a behavior.
• A child policy cannot contain CBQ 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.
Examples
# Nest the child policy child in traffic behavior database of the parent policy.
<Sysname> system-view
[Sysname] traffic behavior database
[Sysname-behavior-database] traffic-policy child
