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 attributes for QoS policy definitions.
Setting Up RADIUS Using VSA 38
The RADIUS vendor specific attribute (VSA) 38 is used for downstream traffic going toward a
subscriber. The service (policy map name) to which the user session belongs resides on the RADIUS
server. The router downloads the name of the policy map from RADIUS using VSA 38 in the user profile
and then applies the policy to the session.
To set up RADIUS for per session queuing and shaping for PPPoE over VLAN support, enter the
following vendor specific attribute (VSA) in the user profile on the RADIUS server:
Cisco:Cisco-Policy-Down = <service policy name>
The actual configuration of the policy map occurs on the router. The user profile on the RADIUS service
contains an entry that identifies the policy map name applicable to the user. This policy map name is the
service RADIUS downloads to the router using VSA 38.
Although the router also supports RADIUS VSA 38, Cisco-Policy-Down and Cisco-Policy-Up, we

associated Layer 2 network server (LNS). In the example, the Cisco-Policy-Down attribute indicates the
name of the policy map to be downloaded, which in this example is rad_output_policy. The RADIUS
dictionary file includes an entry for Cisco VSA 38.

abc@hello1.com Password = "cisco123"
Service-Type = Framed-User,
Framed-Protocol = PPP,
Cisco:Cisco-Policy-Down = rad_output_policy
