Three-Level Hierarchical Policies - Cisco ASR 9000 Series Service Configuration Manual

Configuring Hierarchical Modular QoS on Cisco ASR 9000 Series Routers
Two-Level Hierarchical Queueing Policy
A hierarchical Queueing Policy is generally applied on egress, and can be configured by modifying the
hierarchical policing policy in

shape a Frame Relay PVC to a maximum rate (effectively creating an interface with a specific
bandwidth) and then manage the bandwidth of the PVC.
This example is valid only on the SIP 700 for the ASR 9000.
