OL-7433-09
shows how to configure a three-level hierarchical policy. This example configuration
A bottom-level child policy contains two policy maps named DefaultMeter and BusinessMeter.
These policy maps define marking and policing for the associated traffic classes.
A Middle-Level policy defines queuing services for the classes. In the Middle-Level policy map, the
bottom-level BusinessMeter policy is applied to the Business class and the bottom-level
DefaultMeter policy is applied to the Non-Business class.
The Middle-Level policy is applied to the class-default class in the parent policy map named
Top-Level, which shapes the traffic to 8000 kbps.
The hierarchical policy is attached to PVC 1/32 on the point-to-point ATM subinterface 1/0/0.1 in
the outbound direction.
