Abstract
This document 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 document obsoletes RFC 3636. It amends that specification by moving MAU type OBJECT-IDENTITY definitions and relevant textual conventions into a separate Internet Assigned Number Authority (IANA) maintained MIB module. In addition, management information is added to enable support for Ethernet in the First Mile (EFM) and 10GBASE-CX4 MAUs.
This document 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 [IEEE802.3] Medium Attachment Units (MAUs).
The previous version of this document, RFC 3636 [RFC3636], defined a single MIB module. This document splits the original MIB module into two, putting frequently updated object identities and textual conventions into a separate, IANA-maintained MIB module, in order to decrease the need of updating the basic MAU MIB module.
The first version of the IANA-maintained MIB module also extends the list of managed objects to support Ethernet in the First Mile (EFM) and 10GBASE-CX4 interfaces.
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.
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].
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].
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. 802.3-2005 [IEEE802.3]. This specification is intended to provide for management of all types of Ethernet/802.3 MAUs.
The management definitions provided in this document are intended to be a superset of those defined by RFC 3636 [RFC3636].
In order to decrease the need of updating the basic MAU MIB module due to the new MAU type, Media Available state, Auto Negotiation capability and/or Jack type introduction, all relevant object identities and textual conventions have been moved to a separate, IANA-maintained MIB module IANA-MAU-MIB, the first version of which is defined in this document. Thus when a new MAU type, Media Available state, Auto Negotiation capability, and/or Jack type is defined by the IEEE 802.3 working group, only the IANA-maintained module needs to be revised, leaving the basic MAU-MIB module defined in this document unchanged.
In addition, the new definitions are added to the IANA-maintained MIB module, to support Ethernet in the First Mile (EFM) and 10GBASE-CX4 interfaces, defined in IEEE Std 802.3ah-2004 [IEEE802.3ah] and IEEE Std 802.3ak-2004 [IEEE802.3ak] respectively, now part of IEEE Std 802.3-2005 [IEEE802.3].
It should be noted that the changes made in this revision will not be entirely backward-compatible with MIB modules that currently import MAU type object identity descriptors from the MAU-MIB; such modules will need to be revised to import those DESCRIPTORS from the IANA- MAU-MIB. Similarly, any management applications that process the object identity definitions (e.g., to present the DESCRIPTION text to a user) will need to get those definitions from the IANA-MAU-MIB instead of the MAU-MIB. While it is true that changes that require such adjustments are not strictly compliant with the SMIv2 rules
Beili Standards Track [Page 4]
RFC 4836 MAU MIB April 2007
governing MIB module revisions (see [RFC2578] Section 10), in this case continued high maintenance costs that would result from not making these changes make the deviation from the rules justified. It should be noted that the working group was not able to find any examples of MIB modules or management applications that would actually be negatively affected by the changes.
It is assumed that an agent implementing MAU-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.
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 the MAU-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.

RFC 4836 MAU MIB April 2007
(Note that repeater ports are not represented as interfaces in the Interface MIB.)
3.2.2. Relationship to the 802.3 Repeater MIB Module
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 module.
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 that the given MAU is connected to.
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.
This section contains the mapping between relevant managed objects (attributes) defined in [IEEE802.3] Clause 30, and managed objects defined in this document.
The dot3MauType OBJECT IDENTIFIER and its OBJECT-IDENTITY definitions has been moved from the MAU-MIB into the IANA-maintained IANA-MAU- MIB, the first version of which is defined in this document.
When a new IEEE 802.3 MAU is defined, IANA can re-issue a version of IANA-MAU-MIB with the new dot3MauType OBJECT-IDENTITY and its matching IANAifMauTypeListBits textual convention value and, possibly, with new IANAifMauMediaAvailable, IANAifMauAutoNegCapBits, and/or IANAifJackType values.
An Expert Review, as defined in RFC 2434 [RFC2434], is REQUIRED for the addition of the new MAU, Media Available states, Auto Negotiation capabilities, and/or Jack types.
In some cases, new MAU types may require additional managed objects or may have side effects on the behavior of existing managed objects. In such cases a standards-track specification (which may be a new document or a revision of this document) is also REQUIRED. Any such document is REQUIRED to note any special properties of the MAU types that it defines - for example, side effects on the ifStackTable as noted in this document for 10GBASE-W MAUs.
The syntax of ifMauTypeListBits is changed to be a textual convention, such that the enumerated integer values are now defined in the textual convention IANAifMauTypeListBits, which can be re- specified (with additional values, when defined by IEEE 802.3) in the IANA-maintained MIB module without issuing a new version of this document.
The syntax of ifMauMediaAvailable and rpMauMediaAvailable is changed to be a textual convention, such that the enumerated integer values are now defined in the textual convention IANAifMauMediaAvailable, which can be re-specified (with additional values, when defined by IEEE 802.3) in the IANA-maintained MIB module without issuing a new version of this document.
The syntax of ifMauAutoNegCapabilityBits, ifMauAutoNegCapAdvertisedBits, and ifMauAutoNegCapReceivedBits objects is changed to be a textual convention, such that the enumerated integer values are now defined in the textual convention IANAifMauAutoNegCapBits, which can be re-specified (with additional values, when defined by IEEE 802.3) in the IANA-maintained MIB module without issuing a new version of this document.
The JackType Textual Convention has been deprecated in favor of the IANAifJackType defined in the IANA-maintained MIB module, so the new Jack types can be added (when defined by IEEE 802.3) without issuing a new version of this document.

ifMauTypeList OBJECT-TYPE SYNTAX Integer32 MAX-ACCESS read-only STATUS deprecated DESCRIPTION "********* THIS OBJECT IS DEPRECATED **********
This object has been deprecated in favour of ifMauTypeListBits.
A value that uniquely identifies the set of possible IEEE 802.3 types that the MAU could be. The value is a sum that initially takes the value zero. Then, for each type capability of this MAU, 2 raised to the power noted below is added to the sum. For example, a MAU that has the capability to be only 10BASE-T would have a value of 512 (2**9). In contrast, a MAU that supports both 10Base-T (full duplex) and 100BASE-TX (full duplex) would have a value of ((2**11) + (2**16)), or 67584.

ifMauDefaultType OBJECT-TYPE SYNTAX AutonomousType MAX-ACCESS read-write STATUS current DESCRIPTION "This object identifies the default administrative baseband MAU type to be used in conjunction with the operational MAU type denoted by ifMauType.
The set of possible values for this object is the same as the set defined for the ifMauType object.
This object represents the administratively-configured type of the MAU. If auto-negotiation is not enabled or is not 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 of this object denotes the type to which the MAU will automatically revert if/when auto-negotiation is later disabled.
NOTE TO IMPLEMENTORS: It may be necessary to provide for underlying hardware implementations which do not follow the exact behavior specified above. In particular, when ifMauAutoNegAdminStatus transitions from enabled to disabled, the agent implementation MUST ensure that the operational type of the MAU (as reported by ifMauType) correctly transitions to the value specified by this object, rather than continuing to operate at the value earlier determined by the auto-negotiation function."

remoteLinkLoss(8) - remote fault, due to link loss remoteTest(9) - remote fault, due to test offline(10) - offline, Clause 37 Auto-Negotiation only autoNegError(11) - Auto-Negotiation Error, Clause 37 Auto-Negotiation only pmdLinkFault(12) - PMA/PMD receive link fault. In case of PAF (2BASE-TL / 10PASS-TS PHYs), all PMEs in the aggregation group have detected a link fault wisFrameLoss(13) - WIS loss of frame, 10GBASE-W only wisSignalLoss(14) - WIS loss of signal, 10GBASE-W only pcsLinkFault(15) - PCS receive link fault excessiveBER(16) - PCS Bit Error Ratio monitor reporting excessive error ratio dxsLinkFault(17) - DTE XGXS receive link fault, XAUI only pxsLinkFault(18) - PHY XGXS receive link fault, XAUI only availableReduced(19) - link normal, reduced bandwidth, 2BASE-TL / 10PASS-TS only ready(20) - at least one PME in the aggregation group is detecting handshake tones, 2BASE-TL / 10PASS-TS only
If the MAU is a 10M b/s 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, 10BASE2, 10BASE5, or 10BROAD36 MAU, this indicates whether loopback is detected on the DI circuit. The value of this attribute persists between packets for MAU types AUI, 10BASE5, 10BASE2, 10BROAD36, and 10BASEFP.
At power-up or following a reset, the Media Available state will be unknown(2) for AUI, 10BASE5, 10BASE2, 10BROAD36, 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 Media Available state will only change during noncollided transmissions for AUI, 10BASE2, 10BASE5, 10BROAD36, and 10BASE-FP MAUs.
For 100BASE-T2, 100BASE-T4, 100BASE-TX, 100BASE-FX, 100BASE-LX10, and 100BASE-BX10 PHYs the enumerations match the states within the link integrity state diagram. Any MAU that implements management of [IEEE802.3] Clause 28 Auto-Negotiation, will map remote fault indication to remoteFault(5).
Beili Standards Track [Page 50]
RFC 4836 MAU MIB April 2007
Any MAU that implements management of Clause 37 Auto-Negotiation, will map the received RF1 and RF2 bits as follows: Offline maps to offline(10), Link_Failure maps to remoteFault(5), and Auto-Negotiation Error maps to autoNegError(11).
The value remoteFault(5) applies to 10BASE-FB remote fault indication, the 100BASE-X far-end fault indication, and nonspecified remote faults from a system running Clause 28 Auto-Negotiation.
The value remoteJabber(7), remoteLink loss(8), or remoteTest(9) SHOULD be used instead of remoteFault(5) where the reason for remote fault is identified in the remote signaling protocol. Where a Clause 22 MII or Clause 35 GMII is present, a logic one in the remote fault bit maps to the value remoteFault(5), a logic zero in the link status bit maps to the enumeration notAvailable(4). The value notAvailable(4) takes precedence over remoteFault(5).
For 2BASE-TL and 10PASS-TS PHYs, the value unknown(2) maps to the condition where the PHY (PCS with connected PMEs) is initializing, the value ready(20) maps to the condition where the interface is down and at least one PME in the aggregation group is ready for handshake, the value available(3) maps to the condition where all the PMEs in the aggregation group are up, the value notAvailable(4) maps to the condition where all the PMEs in the aggregation group are down and no handshake tones are detected, the value availableReduced(19) maps to the condition where the interface is up, a link fault is detected at the receive direction by one or more PMEs in the aggregation group, but at least one PME is up and the enumeration pmdLinkFault(12) maps to the condition where a link fault is detected at the receive direction by all of the PMEs in the aggregation group.
For 10 Gb/s the enumerations map to value of the link_fault variable within the Link Fault Signaling state diagram as follows: the value OK maps to the value available(3), the value Local Fault maps to the value notAvailable(4), and the value Remote Fault maps to the value remoteFault(5). The value pmdLinkFault(12), wisFrameLoss(13), wisSignalLoss(14), pcsLinkFault(15), excessiveBER(16), or dxsLinkFault(17) SHOULD be used instead of the value notAvailable(4), where the reason for the Local Fault state can be identified through the use of the Clause 45 MDIO Interface. Where multiple reasons for the Local Fault state can be identified, only the highest precedence error SHOULD be

reported. This precedence in descending order is as follows:
Where a Clause 45 MDIO interface is present a logic zero in the PMA/PMD Receive link status bit ([IEEE802.3] Section 45.2.1.2.2) maps to the value pmdLinkFault(12), logic one in the LOF status bit (Section 45.2.2.10.4) maps to the value wisFrameLoss(13), a logic one in the LOS status bit (Section 45.2.2.10.5) maps to the value wisSignalLoss, a logic zero in the PCS Receive link status bit (Section 45.2.3.2.2) maps to the value pcsLinkFault(15), a logic one in the 10GBASE-R PCS Latched high BER status bit (Section 45.2.3.12.2) maps to the value excessiveBER, a logic zero in the DTE XS receive link status bit (Section 45.2.5.2.2) maps to the value dxsLinkFault(17) and a logic zero in the PHY XS transmit link status bit (Section 45.2.4.2.2) maps to the value pxsLinkFault(18).

The IANA-MAU-MIB does not define any management objects. Instead, it defines a set of textual conventions which are used by the MAU-MIB and may be used by other MIB modules to define management objects. Meaningful security considerations can only be written for MIB modules that define management objects.
There are a number of management objects defined in the MAU-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 the MAU-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.
Beili Standards Track [Page 62]
RFC 4836 MAU MIB April 2007
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 the MAU-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 the MAU-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.
This document defines first version of the IANA-maintained IANA-MAU- MIB module. It is intended that each new MAU type, Media Available state, Auto Negotiation capability, and/or Jack type defined by the IEEE 802.3 working group and approved for publication in a revision of IEEE Std 802.3 will be added to the IANA-maintaned MIB module, provided that it is suitable for being managed by the base objects in the MAU-MIB module.
For each new MAU type added, a short description of the MAU technology and, wherever possible, a reference to a publicly available specification SHOULD be specified. An Expert Review, as defined in RFC 2434 [RFC2434], is REQUIRED, for each modification.
This document was produced by the IETF Ethernet Interfaces and Hub MIB Working Group, whose efforts were greatly advanced by the contributions of the following people:
Mike Heard

Dan Romascanu
This document is based on the Proposed Standard MAU MIB, RFC 3636 [RFC3636], edited by John Flick of Hewlett-Packard, and produced by

the Ethernet Interfaces and Hub MIB Working Group. It extends that document by moving the object identities and textual conventions for MAU types into a IANA-maintained MIB module. In addition, support is provided for the EFM and 10GBASE-CX4 MAUs as defined in [IEEE802.3ah] and [IEEE802.3ak] respectively.
RFC 3636, in turn, was 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, PAUSE negotiation and remote fault status 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, auto-negotiation, and jack management as defined in [IEEE802.3].
