             for IEEE 802.3 Medium Attachment Units (MAUs)

Status of this Memo

   This RFC 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" for the standardization state and status
   of this protocol.  Distribution of this memo is unlimited.

Abstract

   This document defines a portion of the Management Information Base
   (MIB) for use with network management protocols in TCP/IP-based
   internets.  In particular, it defines objects for managing IEEE 802.3
   Medium Attachment Units (MAUs).

1.  The Network Management Framework

   The Internet-standard Network Management Framework consists of three
   components.  They are:

      STD 16, RFC 1155 [1] which defines the SMI, the mechanisms used
      for describing and naming objects for the purpose of management.
      STD 16, RFC 1212 [7] defines a more concise description mechanism,
      which is wholly consistent with the SMI.

      STD 17, RFC 1213 [4] which defines MIB-II, the core set of managed
      objects for the Internet suite of protocols.

      STD 15, RFC 1157 [3] which defines the SNMP, the protocol used for
      network access to managed objects.

   The Framework permits new objects to be defined for the purpose of
   experimentation and evaluation.

2.  Object Definitions

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  Objects in the MIB are
   defined using the subset of Abstract Syntax Notation One (ASN.1)
   defined in the SMI.  In particular, each object object type is named
   by an OBJECT IDENTIFIER, an administratively assigned name.  The
   object type together with an object instance serves to uniquely
   identify a specific instantiation of the object.  For human
   convenience, we often use a textual string, termed the descriptor, to
   refer to the object type.

3.  Overview

   Instances of the object types defined in this document represent
   attributes of an IEEE 802.3 MAU.  Several types of MAUs are defined
   in the IEEE 802.3/ISO 8802-3 CSMA/CD standard [9].

   These MAUs may be connected to IEEE 802.3 repeaters or to 802.3
   (Ethernet-like) interfaces.  For convenience this document refers to
   these devices as "repeater MAUs" and "interface MAUs."

   The definitions presented here are based on Draft 5 of Section 20 of
   IEEE P802.3p, "Layer Management for 10 Mb/s Medium Attachment Units
