IESG Note

   This RFC is not a candidate for any level of Internet Standard.  The
   IETF disclaims any knowledge of the fitness of this RFC for any
   purpose and in particular notes that the decision to publish is not
   based on IETF review for such things as security, congestion control,
   or inappropriate interaction with deployed protocols.  The RFC Editor
   has chosen to publish this document at its discretion.  Readers of
   this document should exercise caution in evaluating its value for

Abstract

   This document describes the set of Remote Authentication Dial-In User
   Service Vendor-Specific Attributes (RADIUS VSAs) defined by the DSL
   Forum.

   These attributes are designed to transport Digital Subscriber Line
   (DSL) information that is not supported by the standard RADIUS
   attribute set.  It is expected that this document will be updated if
   and when the DSL Forum defines additional vendor-specific attributes,
   since its primary purpose is to provide a reference for DSL equipment
   vendors wishing to interoperate with other vendors' products.
