Dynamically Applying QoS Policies to PPP Sessions on ATM VCs
The router allows you to dynamically apply QoS policy maps to PPPoA and PPPoEoA sessions using

the following attribute-value (AV) pairs on RADIUS to specify the name of the policy map to
dynamically apply to the session:
"ip:sub-qos-policy-in=<name of the QoS policy in ingress direction>"
"ip:sub-qos-policy-out=<name of egress policy>"
You define the AV-pairs in one of the following RADIUS profiles:
