Abstract

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 obsoletes RFC 2668. This memo extends that specification by including management information useful for the management of 10 gigabit per second (Gb/s) MAUs. This memo also obsoletes RFC 1515.

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.

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.

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.

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.

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

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

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.

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,

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.)

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.

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.

                   support setting the value of this object to some
                   of the enumerated values.
                   The value other(1) is returned if the MAU is in
                   a state other than one of the states 2 through
                   6.
                   The value unknown(2) is returned when the MAU's
                   true state is unknown; for example, when it is
                   being initialized.
                   A MAU in the operational(3) state is fully
                   functional, operates, and passes signals to its
                   attached DTE or repeater port in accordance to
                   its specification.
                   A MAU in standby(4) state forces DI and CI to
                   idle and the media transmitter to idle or fault,
                   if supported.  Standby(4) mode only applies to
                   link type MAUs.  The state of
                   rpMauMediaAvailable is unaffected.
                   A MAU in shutdown(5) state assumes the same
                   condition on DI, CI, and the media transmitter
                   as though it were powered down or not connected.
                   The MAU MAY return other(1) value for the
                   rpMauJabberState and rpMauMediaAvailable objects
                   when it is in this state.  For an AUI, this
                   state will remove power from the AUI.
                   Setting this variable to the value reset(6)
                   resets the MAU in the same manner as a
                   power-off, power-on cycle of at least one-half
                   second would.  The agent is not required to
                   return the value reset (6).
                   Setting this variable to the value
                   operational(3), standby(4), or shutdown(5)
                   causes the MAU to assume the respective state
                   except that setting a mixing-type MAU or an AUI
                   to standby(4) will cause the MAU to enter the

                   the link test fail state/low light function.
                   For an AUI or a coax (including broadband) MAU
                   this indicates whether or not loopback is
                   detected on the DI circuit.  The value of this
                   attribute persists between packets for MAU types
                   AUI, 10BASE5, 10BASE2, 10BROAD36, and 10BASE-FP.
                   The value other(1) is returned if the
                   mediaAvailable state is not one of 2 through 11.
                   The value unknown(2) is returned when the MAU's
                   true state is unknown; for example, when it is
                   being initialized.  At power-up or following a
                   reset, the value of this attribute will be
                   unknown for AUI, coax, and 10BASE-FP MAUs.  For
                   these MAUs loopback will be tested on each
                   transmission during which no collision is
                   detected.  If DI is receiving input when DO
                   returns to IDL after a transmission and there
                   has been no collision during the transmission
                   then loopback will be detected.  The value of
                   this attribute will only change during
                   non-collided transmissions for AUI, coax, and
                   10BASE-FP MAUs.
                   For 100Mbps and 1000Mbps MAUs, the enumerations
                   match the states within the respective link
                   integrity state diagrams, fig 32-16, 23-12 and
                   24-15 of sections 32, 23 and 24 of [IEEE802.3].
                   Any MAU which implements management of
                   auto-negotiation will map remote fault
                   indication to remote fault.
                   The value available(3) indicates that the link,
                   light, or loopback is normal.  The value
                   notAvailable(4) indicates link loss, low light,
                   or no loopback.
                   The value remoteFault(5) indicates that a fault
                   has been detected at the remote end of the link.
                   This value applies to 10BASE-FB, 100BASE-T4 Far
                   End Fault Indication and non-specified remote
                   faults from a system running auto-negotiation.
                   The values remoteJabber(7), remoteLinkLoss(8),
                   and remoteTest(9) SHOULD be used instead of
                   remoteFault(5) where the reason for remote fault
                   is identified in the remote signaling protocol.
                   The value invalidSignal(6) indicates that an
                   invalid signal has been received from the other
                   end of the link.  invalidSignal(6) applies only
                   to MAUs of type 10BASE-FB.
                   Where an IEEE Std 802.3-2002 clause 22 MII
                   is present, a logic one in the remote fault bit
                   (reference section 22.2.4.2.8 of that document)
                   maps to the value remoteFault(5), and a logic
                   zero in the link status bit (reference section
                   22.2.4.2.10 of that document) maps to the value
                   notAvailable(4).  The value notAvailable(4)
                   takes precedence over the value remoteFault(5).
                   Any MAU that implements management of clause 37
                   Auto-Negotiation will map the received Remote
                   Fault (RF1 and RF2) bit values for Offline to
                   offline(10), Link Failure to remoteFault(5) and
                   Auto-Negotiation Error to autoNegError(11)."

                   The value unknown(2) is returned when the MAU's
                   true state is unknown; for example, when it is
                   being initialized.
                   A MAU in the operational(3) state is fully
                   functional, operates, and passes signals to its
                   attached DTE or repeater port in accordance to
                   its specification.
                   A MAU in standby(4) state forces DI and CI to
                   idle and the media transmitter to idle or fault,
                   if supported.  Standby(4) mode only applies to
                   link type MAUs.  The state of
                   ifMauMediaAvailable is unaffected.
                   A MAU in shutdown(5) state assumes the same
                   condition on DI, CI, and the media transmitter
                   as though it were powered down or not connected.
                   The MAU MAY return other(1) value for the
                   ifMauJabberState and ifMauMediaAvailable objects
                   when it is in this state.  For an AUI, this
                   state will remove power from the AUI.
                   Setting this variable to the value reset(6)
                   resets the MAU in the same manner as a
                   power-off, power-on cycle of at least one-half
                   second would.  The agent is not required to

                   Setting this variable to the value
                   operational(3), standby(4), or shutdown(5)
                   causes the MAU to assume the respective state
                   except that setting a mixing-type MAU or an AUI

       STATUS      current
       DESCRIPTION "If the MAU is a link or fiber type (FOIRL,
                   10BASE-T, 10BASE-F) then this is equivalent to
                   the link test fail state/low light function.
                   For an AUI or a coax (including broadband) MAU
                   this indicates whether or not loopback is
                   detected on the DI circuit.  The value of this
                   attribute persists between packets for MAU types
                   AUI, 10BASE5, 10BASE2, 10BROAD36, and 10BASE-FP.
                   The value other(1) is returned if the
                   mediaAvailable state is not one of 2 through 18.
                   The value unknown(2) is returned when the MAU's
                   true state is unknown; for example, when it is
                   being initialized.  At power-up or following a
                   reset, the value of this attribute will be
                   unknown for AUI, coax, and 10BASE-FP MAUs.  For
                   these MAUs loopback will be tested on each
                   transmission during which no collision is
                   detected.  If DI is receiving input when DO
                   returns to IDL after a transmission and there
                   has been no collision during the transmission
                   then loopback will be detected.  The value of
                   this attribute will only change during
                   non-collided transmissions for AUI, coax, and
                   10BASE-FP MAUs.
                   For 100Mbps and 1000Mbps MAUs, the enumerations
                   match the states within the respective link
                   integrity state diagrams, fig 32-16, 23-12 and
                   24-15 of sections 32, 23 and 24 of [IEEE802.3].
                   Any MAU which implements management of
                   auto-negotiation will map remote fault
                   indication to remote fault.
                   The value available(3) indicates that the link,
                   light, or loopback is normal.  The value
                   notAvailable(4) indicates link loss, low light,
                   or no loopback.
                   The value remoteFault(5) indicates that a fault
                   has been detected at the remote end of the link.
                   This value applies to 10BASE-FB, 100BASE-T4 Far
                   End Fault Indication and non-specified remote
                   faults from a system running auto-negotiation.
                   The values remoteJabber(7), remoteLinkLoss(8),
                   and remoteTest(9) SHOULD be used instead of
                   remoteFault(5) where the reason for remote fault
                   is identified in the remote signaling protocol.
                   The value invalidSignal(6) indicates that an
                   invalid signal has been received from the other
                   end of the link.  invalidSignal(6) applies only
                   to MAUs of type 10BASE-FB.
                   Where an IEEE Std 802.3-2002 clause 22 MII
                   is present, a logic one in the remote fault bit
                   (reference section 22.2.4.2.8 of that document)
                   maps to the value remoteFault(5), and a logic
                   zero in the link status bit (reference section
                   22.2.4.2.10 of that document) maps to the value
                   notAvailable(4).  The value notAvailable(4)
                   takes precedence over the value remoteFault(5).
                   Any MAU that implements management of clause 37
                   Auto-Negotiation will map the received RF1 and
                   RF2 bit values for Offline to offline(10), Link
                   Failure to remoteFault(5) and Auto-Negotiation
                   Error to autoNegError(11).
                   For 10 Gb/s, the enumerations map to the states
                   within the Reconciliation Sublayer state diagram
                   as follows:
                     NoFault maps to the enumeration 'available(3)'
                     LocalFault maps to the enumeration
                       'notAvailable(4)'
                     RemoteFault maps to the enumeration
                       'remoteFault(5)'
                   The enumerations 'pmdLinkFault(12)',
                   'wisFrameLoss(13)', 'wisSignalLoss(14)',
                   'pcsLinkFault(15)', 'excessiveBER(16)', and
                   'dxsLinkFault(17)' and 'pxsLinkFault(18)' should
                   be used instead of the enumeration
                   'notAvailable(4)' where the reason for the local
                   fault can be identified through the use of the
                   MDIO Interface.  Where multiple reasons for the
                   local fault state can be identified only the
                   highest precedence error should be reported.
                   The precedence in descending order is as
                   follows:

                   This object represents the

                   implemented for this MAU, the value of this
                   object determines the operational type of the
                   MAU.  In this case, a set to this object will
                   force the MAU into the specified operating mode.
                   If auto-negotiation is implemented and enabled
                   for this MAU, the operational type of the MAU
                   is determined by auto-negotiation, and the value

                   ensure that the operational type of the MAU (as

This document is based on the Proposed Standard MAU MIB, RFC 2668 RFC2668, edited by John Flick of Hewlett-Packard and Andrew Smith, then of Extreme Networks, and produced by the Ethernet Interfaces and Hub MIB Working Group. It extends that document by providing support for 10 Gb/s MAUs as defined in [IEEE802.3ae].

RFC 2668, in turn, was based on the Proposed Standard MAU MIB, RFC 2239 RFC2239, edited by Kathryn de Graaf, then of 3Com, and Dan Romascanu, then of Madge Networks, and produced by the Ethernet Interfaces and Hub MIB Working Group. It extended that document by providing support for 1000 Mb/sec MAUs as defined in [IEEE802.3].

RFC 2239, in turn, was based on the Proposed Standard MAU MIB, RFC 1515 RFC1515, edited by Donna McMaster, then of SynOptics Communications, Keith McCloghrie, then of Hughes LAN Systems, and Sam Roberts, then of Farallon Computing, and produced by the Hub MIB Working Group. It extends that document by providing support for 100 Mb/sec MAUs, full duplex MAUs, and auto-negotiation, as defined in [IEEE802.3].

Security Considerations

There are a number of management objects defined in this MIB that have a MAX-ACCESS clause of read-write. Setting these objects can have a serious effect on the operation of the network, including:

o enabling or disabling a MAU

o changing a MAU's default type

o enabling, disabling or restarting autonegotiation

o modifying the capabilities that a MAU advertizes during

  autonegotiation.

Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations.

Some of the readable objects in this MIB module (i.e., objects with a MAX-ACCESS other than not-accessible) may be considered sensitive or vulnerable in some network environments. In some environments it may be undesirable to allow unauthorized parties to access statistics or status information about individual links in a network. It is thus important to control even GET and/or NOTIFY access to these objects and possibly to even encrypt the values of these objects when sending them over the network via SNMP.

SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPSec), even then, there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB module.

It is recommended that the implementors consider the security features as provided by the SNMPv3 framework (see RFC3410, section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy).

Furthermore, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them.

A. Change Log

A.1. Changes since RFC 2668
