Chapter 5 Dynamic Service Policy Modifications

ATM Virtual Circuit QoS Policy

When the downstream interface on the BRAS-to-DSLAM is an ATM port, the subscriber session
terminates on the ATM PVC. The router uses the ANCP-signaled rate to set up the policing rate for
priority services such as voice and video. Therefore, you are not required to define a shaping rate for the
ATM port. Instead, you can define the ATM QoS policy-map using any of the QoS actions available to
child policies. For more information, see the QoS actions listed in the
Actions" section on page
In the absence of a QoS policy, the router applies the default ATM QoS policy to the ATM PVC on
which the session terminates.

Dynamic and Default QoS Policy Precedence

You can have only one policy-map applied to a subscriber session at any given time. When present, the
ISG always applies the dynamic policy. The dynamic policy always has precedence over the default
policy.
In the absence of a dynamic policy, the default policy provides the minimum shaping capability. The
ISG uses the default policy when ANCP communication is not established (for example, during ISG
startup) and when the ISG fails to establish the dynamic QoS policy.

Parameterized Actions

This section lists the actions supported for service and QoS policy parameterization and includes the
following topics:
•
•
•
Note The default values for the RADIUS VSA parameters are the same as the default values for the equivalent
modular QoS CLI (MQC) commands.
