1.  Introduction

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it defines objects for managing IEEE 802.3 Medium
   Attachment Units (MAUs).

   This memo also includes a MIB module.  This MIB module extends the
   list of managed objects specified in the earlier version of this MIB
   module, RFC 2668 [RFC2668].

   Ethernet technology, as defined by the 802.3 Working Group of the
   IEEE, continues to evolve, with scalable increases in speed, new
   types of cabling and interfaces, and new features.  This evolution
   may require changes in the managed objects in order to reflect this
   new functionality.  This document, as with other documents issued by
   this working group, reflects a certain stage in the evolution of
   Ethernet technology.  In the future, this document might be revised,
   or new documents might be issued by the Ethernet Interfaces and Hub
   MIB Working Group, in order to reflect the evolution of Ethernet
   technology.

   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 [RFC2119].

2.  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].

3.  Overview

   Instances of these object types represent attributes of an IEEE 802.3
   MAU.  Several types of MAUs are defined in the IEEE 802.3 CSMA/CD
   standard [IEEE802.3].  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 Section 30.5, "Layer
   Management for 10 Mb/s, 100 Mb/s, 1000 Mb/s and 10 Gb/s Medium
   Attachment Units (MAUs)", Section 30.6, "Management for link Auto-
   Negotiation", and Annex 30A, "GDMO Specifications for 802.3 managed
   object classes" of IEEE Std. 802.3, 2002 edition [IEEE802.3], as
   amended by IEEE Std. 802.3ae-2002 [IEEE802.3ae].  That specification
   includes definitions for 10 Mb/s, 100 Mb/s, 1000 Mb/s and 10 Gb/s
   devices.  This specification is intended to serve the same purpose:
   to provide for management of all types of Ethernet/802.3 MAUs.

3.1.  Relationship to RFC 2668

   This MIB is intended to be a superset of that defined by RFC 2668
   [RFC2668].  This MIB includes all of the objects contained in that
   MIB, with new and updated definitions which provide support for
   additional capabilities.  Implementors are encouraged to support all
   applicable conformance groups in order to make the best use of the
   new functionality provided by this MIB.  The new and updated
   definitions provide management support for 10 Gb/s devices.

Top      ToC       Page 4 
3.2.  Relationship to RFC 2239

   RFC 2668 was a replacement for RFC 2239 [RFC2239].  RFC 2668 defined
   a superset of that defined by RFC 2239, which contained all of the
   objects defined in RFC 2239, plus several new ones which provide
   additional capabilities.  The new objects provided management support
   for:

   o  management of 1000 Mb/s devices

   o  management of PAUSE negotiation

   o  management of remote fault status

3.3.  Relationship to RFC 1515

   RFC 2239 was a replacement for RFC 1515 [RFC1515].  RFC 2239 defined
   a superset of RFC 1515 which contained all of the objects defined in
   RFC 1515, plus several new ones which provided additional
   capabilities.  The new objects in RFC 2239 provided management
   support for:

   o  management of 100 Mb/s devices

   o  auto-negotiation on interface MAUs

   o  jack management

3.4.  Relationship to Other MIBs

   It is assumed that an agent implementing this MIB will also implement
   (at least) the 'system' group defined in the SNMPv2 MIB [RFC3418].
   The following sections identify other MIBs that such an agent should
   implement.

3.4.1.  Relationship to the Interfaces MIB.

   The sections of this document that define interface MAU-related
   objects specify an extension to the Interfaces MIB [RFC2863].  An
   agent implementing these interface-MAU related objects MUST also
   implement the relevant groups of the ifCompliance3 MODULE-COMPLIANCE
   statement of the Interface MIB.  The value of the object ifMauIfIndex
   is the same as the value of 'ifIndex' used to instantiate the
   interface to which the given MAU is connected.

   It is REQUIRED that an agent implementing the interface-MAU related
   objects in this MIB will also fully comply with the dot3Compliance2
   MODULE-COMPLIANCE statement of the Ethernet-like Interfaces MIB,

Top      ToC       Page 5 
   [RFC3635].  Furthermore, when the interface-MAU related objects are
   used to manage a 10GBASE-W PHY -- i.e., when ifMauType is equal to
   dot3MauType10GigBaseW or any other 10GBASE-W variant -- then the
   agent MUST also support the Ethernet WAN Interface Sublayer (WIS) MIB
   [RFC3637] and must follow the interface layering model specified
   therein.  In that case the value of the object ifMauIfIndex is the
   same as the value of 'ifIndex' for the layer at the top of the stack,
   i.e., for the ifTable entry that has 'ifType' equal to
   ethernetCsmacd(6).  If the interface-MAU related objects are used to
   manage a PHY that allows the MAU type to be changed dynamically, then
   the agent SHALL create ifTable, ifStackTable, and ifInvStackTable
   entries that pertain to the WIS when ifMauDefaultType is changed to a
   10GBASEW variant (i.e., one of dot3MauType10GigBaseW,
   dot3MauType10GigBaseEW, dot3MauType10GigBaseLW, or
   dot3MauType10GigBaseSW) from any other type, and shall destroy the
   WIS-related entries when ifMauDefaultType is changed to a non-
   10GBASE-W type.  The agent SHALL also change the values of
   'ifConnectorPresent' and 'ifHighSpeed' in the ifTable entry indexed
   by ifMauIfIndex as specified in [RFC3635] and [RFC3637] when
   ifMauDefaultType is manipulated in this way but SHALL NOT otherwise
   alter that entry.

   (Note that repeater ports are not represented as interfaces in the
   Interface MIB.)

3.4.2.  Relationship to the 802.3 Repeater MIB

   The section of this document that defines repeater MAU-related
   objects specifies an extension to the 802.3 Repeater MIB defined in
   [RFC2108].  An agent implementing these repeater-MAU related objects
   MUST also comply with the snmpRptrModCompl compliance statement of
   the 802.3 Repeater MIB.

   The values of 'rpMauGroupIndex' and 'rpMauPortIndex' used to
   instantiate a repeater MAU variable SHALL be the same as the values
   of 'rptrPortGroupIndex' and 'rptrPortIndex' used to instantiate the
   port to which the given MAU is connected.

3.5.  Management of Internal MAUs

   In some situations, a MAU can be "internal" -- i.e., its
   functionality is implemented entirely within a device.  For example,
   a managed repeater may contain an internal repeater-MAU and/or an
   internal interface-MAU through which management communications
   originating on one of the repeater's external ports pass in order to
   reach the management agent associated with the repeater.  Such
   internal MAUs may or may not be managed.  If they are managed,
   objects describing their attributes should appear in the appropriate

   MIB subtree:  dot3RpMauBasicGroup for internal repeater-MAUs and
   dot3IfMauBasicGroup for internal interface-MAUs.
