CLI Commands Used to Include DSL Forum VSAs in Access and Accounting Messages

You can use the radius include dsl-forum-attributes command to control the inclusion of a set of DSL Forum VSAs in Access-Request, Acct-Start, Acct-Stop, and (if Acct-Stop messages are specified) Interim-Acct messages that the router sends to RADIUS.

The DSL Forum VSAs, as defined in RFC 4679—DSL Forum Vendor-Specific RADIUS Attributes (September 2006), convey information about the associated subscriber for and data rate of the DSL. A service provider might find it useful to enable inclusion of the DSL Forum VSAs in RADIUS messages in order to bill subscribers for different classes of service based on the data rate of their DSL connection.

Note: JunosE Software also supports several Juniper Networks VSAs that you can use to include DSL-related information. See Juniper Networks VSAs .

The router receives data containing one or more of the DSL Forum VSAs from a DSLAM connected to the router via a PPPoE interface. When you enable the inclusion of the DSL Forum VSAs in these RADIUS messages, the router includes all of the following attributes in the specified message type, provided that the VSA is available in the information that the router receives from the DSLAM.

Note: The router uses the vendor ID assigned to the DSL Forum (3561, or DE9 in hexadecimal format) by the IANA for the DSL Forum VSAs.

For information about enabling the QoS downstream rate application to obtain downstream rates from the Actual-Data-Rate-Downstream [26-130] DSL Forum VSA, see the Configuring the Downstream Rate Using QoS Parameters chapter in JunosE Quality of Service Configuration Guide.
