               RADIUS Authentication Client MIB for IPv6

Status of This Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

Abstract

   This memo defines a set of extensions that instrument RADIUS
   authentication client functions.  These extensions represent a
   portion of the Management Information Base (MIB) for use with network
   management protocols in the Internet community.  Using these
   extensions, IP-based management stations can manage RADIUS
   authentication clients.

   This memo obsoletes RFC 2618 by deprecating the MIB table containing
   IPv4-only address formats and defining a new table to add support for
   version-neutral IP address formats.  The remaining MIB objects from
   RFC 2618 are carried forward into this document.  The memo also adds
   UNITS and REFERENCE clauses to selected objects.

1.  Introduction

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   The objects defined within this memo relate to the Remote
   Authentication Dial-In User Service (RADIUS) Authentication Client as
   defined in RFC 2865 [RFC2865].

2.  Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

   This document uses terminology from RFC 2865 [RFC2865].

   This document uses the word "malformed" with respect to RADIUS
   packets, particularly in the context of counters of "malformed
   packets".  While RFC 2865 does not provide an explicit definition of
   "malformed", malformed generally means that the implementation has
   determined the packet does not match the format defined in RFC 2865.
   Some implementations may determine that packets are malformed when
   the Vendor Specific Attribute (VSA) format does not follow the RFC
   2865 recommendations for VSAs.  Those implementations are used in
   deployments today, and thus set the de facto definition of
   "malformed".

3.  The Internet-Standard Management Framework

   For a detailed overview of the documents that describe the current
   Internet-Standard Management Framework, please refer to section 7 of
   RFC 3410 [RFC3410].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  MIB objects are generally
   accessed through the Simple Network Management Protocol (SNMP).
   Objects in the MIB are defined using the mechanisms defined in the
   Structure of Management Information (SMI).  This memo specifies a MIB
   module that is compliant to the SMIv2, which is described in STD 58,
   RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
   [RFC2580].

4.  Scope of Changes

   This document obsoletes RFC 2618 [RFC2618], RADIUS Authentication
   Client MIB, by deprecating the radiusAuthServerTable table and adding
   a new table, radiusAuthServerExtTable, containing
   radiusAuthServerInetAddressType, radiusAuthServerInetAddress, and
