RFC 3276                  HDSL2-SHDSL-LINE MIB                  May 2002


   A more detailed introduction to the current SNMP Management Framework
   can be found in RFC 2570 [16].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  Objects in the MIB are
   defined using the mechanisms defined in the SMI.

   This memo specifies a MIB module that is compliant to the SMIv2.  A
   MIB conforming to the SMIv1 can be produced through the appropriate
   translations.  The resulting translated MIB must be semantically
   equivalent, except where objects or events are omitted because no
   translation is possible (use of Counter64).  Some machine readable
   information in SMIv2 will be converted into textual descriptions in
   SMIv1 during the translation process.  However, this loss of machine
   readable information is not considered to change the semantics of the
   MIB.

   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 [17].

3.  Introduction

   This document describes an SNMP MIB for managing HDSL2/SHDSL Lines.
   These definitions are based upon the specifications for the HDSL2 and
   SHDSL Embedded Operations Channel (EOC) as defined in ANSI
   T1E1.4/2000-006 [18] and ITU G.991.2 [19].

   The MIB is located in the MIB tree under MIB 2 transmission, as
   discussed in the MIB-2 Integration (RFC 1213 [20] and RFC 2863 [21])
   section of this document.

3.1.  Relationship of the HDSL2/SHDSL Line MIB to other MIBs

   This section outlines the relationship of this MIB with other MIBs
   described in RFCs.  Specifically, IF-MIB as presented in RFC 2863
   [21] is discussed.

3.1.1  General IF-MIB Integration (RFC 2863)

   The HDSL2/SHDSL Line MIB specifies the detailed attributes of a data
   interface.  As such, it needs to integrate with RFC 2863 [21].  The
   IANA has assigned the following ifTypes to HDSL2 and SHDSL:
