Queuing PPP Sessions on ATM VCs
Example of Configuring PPP Session Queuing on ATM VCs
The following example shows how to configure PPPoA or PPPoEoA session queuing. In the example, a
hierarchical QoS policy named pm_hier2_0_2 is associated with Virtual-Template555, which is applied
to the broadband aggregation group named pppoeoa-group.

Example of Configuring and Applying an Hierarchical Policy Map
Example 17-31
shows how to configure a hierarchical policy and apply it to a virtual template. The
example contains a child policy map named child1 with QoS features defined for the gold and bronze
traffic classes. The child1 policy is applied to the parent policy map, which is shaped to 512000 bps. The
hierarchical policy is applied to the virtual template named virtual-template 1.
Example 17-31 Configuring an Hierarchical Policy Map
Router(config)# policy-map child1
Router(config-pmap)# class gold
Router(config-pmap-c)# priority
Router(config-pmap-c)# police percent 40
Router(config-pmap-c)# class bronze
