IANA Considerations for RADIUS (Remote Authentication Dial In User Service)

RFC 3575             IANA Considerations for RADIUS            July 2003


1.2.  Terminology

   The following terms are used here with the meanings defined in BCP
   26:  "name space", "assigned value", "registration".

   The following policies are used here with the meanings defined in BCP
   26: "Private Use", "First Come First Served", "Expert Review",
   "Specification Required", "IESG Approval", "IETF Consensus",
   "Standards Action".

2.  IANA Considerations

   There are three name spaces in RADIUS that require registration:
   Packet Type Codes, Attribute Types, and Attribute Values (for certain
   Attributes).  This document creates no new IANA registries, since a
   RADIUS registry was created by [RFC 2865].

   RADIUS is not intended as a general-purpose protocol, and allocations
   SHOULD NOT be made for purposes unrelated to Authentication,
   Authorization or Accounting.

2.1.  Recommended Registration Policies

   For registration requests where a Designated Expert should be
   consulted, the responsible IESG area director should appoint the
   Designated Expert.  The intention is that any allocation will be
   accompanied by a published RFC.  However, the Designated Expert can
   approve allocations once it seems clear that an RFC will be
   published, allowing for the allocation of values prior to the
   document being approved for publication as an RFC.  The Designated
   Expert will post a request to the AAA WG mailing list (or a successor
   designated by the Area Director) for comment and review, including an
   Internet-Draft.  Before a period of 30 days has passed, the
   Designated Expert will either approve or deny the registration
   request, publish a notice of the decision to the AAA WG mailing list
   or its successor, and inform IANA of its decision.  A denial notice
   must be justified by an explanation and, in the cases where it is
   possible, concrete suggestions on how the request can be modified so
   as to become acceptable.

   Packet Type Codes have a range from 1 to 253.  RADIUS Type Codes 1-5
   and 11-13 were allocated in [RFC 2865], while Type Codes 40-45,
   250-253 are allocated by this document.  Type Codes 250-253 are
   allocated for Experimental Uses, and 254-255 are reserved.  Packet
   Type Codes 6-10, 12-13, 21-34, 50-51 have no meaning defined by an
   IETF RFC, but are reserved until a specification is provided for
   them.  This is being done to avoid interoperability problems with
   software that implements non-standard RADIUS extensions that are or
