Applying Child Policies Under Priority Classes
Applying Child Policies Under Priority Classes
The Cisco 10000 series router allows you to apply a child policy with non-queuing features under a
priority class in Cisco IOS Release 12.2(31)SB2 and later releases. In a three-level hierarchical policy,
the priority class to which you attach the child policy must be in the middle-level policy. In a two-level
hierarchical policy (nested policy), the priority class to which you attach the child policy is in the parent
policy.
For more information, see the Child Service Policy Allowed Under Priority Class feature module for
Cisco IOS Release 12.2(31)SB2.
