DSL Forum Vendor-Specific Attributes
Digital Subscriber Line (DSL) attributes are RADIUS vendor-specific attributes (VSAs) that are defined by the DSL Forum. The attributes transport DSL information that is not supported by standard RADIUS attributes and which convey information about the associated DSL subscriber and data rate. The attributes are defined in RFC 4679, DSL Forum Vendor-Specific RADIUS Attributes.
 | Note: Junos OS uses the vendor ID 3561, which is assigned by the Internet Assigned Numbers Authority (IANA), for the DSL Forum VSAs. |
Subscriber management does not process DSL values—the router simply passes the values received from the subscriber to the RADIUS server, without performing any parsing or manipulation. However, you can manage the content of DSL VSA values either by using the client configuration to restrict the DSL VSAs that the client sends, or by configuring the RADIUS server to ignore unwanted DSL VSAs.
Table 1 describes the DSL Forum VSAs.
