Configuring PPP Session Queuing Using RADIUS

To configure PPPoA or PPPoEoA session queuing using RADIUS, perform the following configuration
tasks:
•
•
Configuring the Policy Map
The router allows you to use RADIUS to apply QoS policy maps to PPPoA or PPPoEoA sessions. The
actual configuration of the policy map, however, occurs on the router using the modular QoS CLI
(MQC).
To configure QoS policy maps and apply them to virtual template interfaces, see the
Hierarchical QoS Policy" section on page 17-54
a Virtual Template" section on page
Adding the Cisco QoS AV Pairs to the RADIUS Profile
Cisco attribute-value (AV) pairs are vendor-specific attributes (VSAs) that allow vendors such as Cisco
to support their own extended attributes. RADIUS attribute 26 is a Cisco VSA used to communicate
vendor-specific information between the router and the RADIUS server.
The RADIUS user profile contains an entry for each user that the RADIUS server authenticates. Each
entry establishes an attribute the user can access. When configuring PPPoA or PPPoEoA session queuing
using RADIUS, enter the following Cisco AV-pair in the appropriate user profile:
Cisco-AVPair = "ip:sub-qos-policy-out=<name of egress policy>"
The Cisco AV-pair identifies the policy map the router is to use when applying QoS features to a PPPoA
or PPPoEoA session. After receiving a service-logon request from the policy server, RADIUS sends a
change of authorization (CoA) request to the router to activate the service for the user, who is already
logged in. If the authorization succeeds, the router downloads the name of the policy map from RADIUS
using the Cisco AV-pair and applies the QoS policy to the session.
Although the router also supports the RADIUS vendor specific attribute (VSA) 38, Cisco-Policy-Down
Note
and Cisco-Policy-Up, we recommend that you use the above attribute for QoS policy definitions. For
more information about attribute 38, see the
page
