Simultaneous QoS Policy Map on an Interface and PPP Session
•
•
The BRAS recognizes that simultaneous policy maps exist and applies the appropriate QoS services to
the packets that are subject to both policies. The BRAS aggregates all of the packets of sessions at the
interface level. For example, if policing is applied on a traffic class in an interface policy, the BRAS
polices the aggregate of all of the packets on any of the sessions that match that class.

Simultaneous Policies and Displaying Statistical Information

To display information about simultaneous policies and their associated statistical information, the
output from the show commands display information at both the interface level and the session level. At
the session level, a unique session owns each policy, and the QoS actions and statistics displayed apply
to that unique session. At the interface level, however, the BRAS treats all of the sessions in aggregate.
The information the BRAS gathers for display represents the aggregate QoS actions and statistics of all
of the sessions passing over the PVC or VLAN.
For simultaneous policies, the way in which the BRAS processes actions at one policy level and at a
subsequent policy level is consistent with the behavior of the BRAS when processing hierarchical input
policies.

14-2
Session-level policy—You associate this service policy with a PPP session on the VAI or LAC. This
policy must contain only non-queuing QoS actions such as policing and set actions. You can
statically configure this policy under a virtual template or use RADIUS Attributes 37 and 39 to
dynamically associate the policy with the PPP session. The BRAS applies this policy only at the PPP
session level.
Interface-level policy—You apply this service policy to a main interface, an ATM PVC, or an
Ethernet-based subinterface such as a VLAN subinterface. This policy can contain queuing-related
features, but it cannot have hierarchical policing policies. The BRAS applies this policy to the
aggregate traffic associated with a specific interface.
