Configuring PPP Session Queuing on ATM VCs

You can apply hierarchical shaping policies to sessions using a virtual template or RADIUS. When you
apply shaping policies to sessions, do not apply a policy at the VC level on the same VC.
To configure PPP session queuing on ATM VCs, perform one of the following configuration tasks:
•

Configuring PPP Session Queuing Using a Virtual Template

To configure PPPoA or PPPoEoA session queuing using a virtual template, perform the following
configuration tasks:
•
•
•
Configuring an Hierarchical QoS Policy
To configure a hierarchical QoS policy, enter the following commands, beginning in global configuration
mode:
Command
Step 1
Router(config)# policy-map
policy-map-name
OL-7433-09
If the same ATM category (for example, shaped unspecified bit rate (UBR)) contains both high and
low bandwidth VCs, the SAR mechanism can cause low throughput for high bandwidth VCs. The
workaround for this issue is to use different ATM classes for low and high bandwidth VCs. For
example, configure low bandwidth VCs as shaped UBR and high bandwidth VCs as variable bit
rate-nonreal-time (VBR-nrt) or constant bit rate (CBR).
When you apply queuing policies to sessions, do not apply a policy at the VC level on the same VC.
The CLASS-BASED QOS MIB does not include statistics for service policies applied to sessions.
RADIUS accounting does not include queuing statistics.
The router ignores the VC weight when it is configured on a VC with PPP session queuing
configured.

Creates or modifies the child policy. Enters policy-map
configuration mode.
policy-map-name is the name of the child policy map. The name
can be a maximum of 40 alphanumeric characters.
