The AAA Per VC QoS Policy Support feature provides the ability to modify an existing quality of 
service (QoS) profile applied to a session while that session remains active using new Cisco 
attribute-value (AV) pairs that specify service policy output and service policy input.

Use Cisco Feature Navigator to find information about platform support and Cisco IOS software image 
support. Access Cisco Feature Navigator at 

. You must have an account on 

Cisco.com. If you do not have an account or have forgotten your username or password, click Cancel at 
the login dialog box and follow the instructions that appear. 

You should be familiar with defining policy maps for managing subscriber sessions, and with 
configuring QoS traffic conditioning. See the

topics.
