Sending Interface Descriptions to AAA

During authentication the router sends ATM interface descriptions to AAA. AAA passes the descriptions to RADIUS, and they can appear in the Calling-Station-Id attribute [31]. (For information about RADIUS and the Calling-Station-ID attribute, see JUNOSe Broadband Access Configuration Guide.)

By default, the router sends the major interface descriptions to AAA on the SRP. You can configure the router to send VP interface descriptions in place of the major interface descriptions, or to send ATM 1483 subinterface descriptions to AAA on the line module. As a result, the VP or ATM 1483 subinterface descriptions can provide a convenient way to identify or group broadband access subscribers.

If you set up multiple interface descriptions, they have the following precedence:

1. ATM 1483 subinterface description
2. VP interface description
3. Major interface description
