Network Access Servers Requirements: Extended RADIUS Practices

RFC 2882               Extended RADIUS Practices               July 2000


1.1.  Disclaimers

   The data and numbers in this document have been gleaned from public
   sources and vendor documents along the way.  Actual implementation of
   many these features and variation from the documentation has not been
   confirmed.

   This document is a snapshot of known practices at the time of
   writing.  It is not intended to standardize these practices here, or
   keep this document current, beyond initial publication. While some
   detailed information is given, it is not the purpose of this document
   to directly or sufficiently describe the functions mentioned to the
   level of a complete functional specification.

   The author has not transcribed copyrighted material, and is not aware
   of whether any of these practices have of intellectual property
   restrictions.

   Any numeric assignments or functional operations are subject to
   change by vendors without notice.  I would appreciate any direct
   input, preferably first hand, from implementors.

1.2.  Presentation

   Without any easy organization for the material, information is
   arranged in a simple taxonomy from bottom-up complexity:

   -    Attribute Usage

   -    Attribute Data Types

   -    Message Codes

   -    New Operations

2.  Attribute Usage

   The RADIUS RFCs define attribute type ranges and specific attribute
   definitions.


   -    There are about 70 defined RADIUS attributes:

   -    Values 192-223 are reserved for experimental use

   -    Values 224-240 are reserved for implementation-specific use

   -    Values 241-255 are reserved and should not be used.
