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.

RFC 3636 802.3 MAU MIB September 2003
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.
Flick Standards Track [Page 3]
RFC 3636 802.3 MAU MIB September 2003
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,
Flick Standards Track [Page 4]
RFC 3636 802.3 MAU MIB September 2003
[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

The value unknown(2) is returned when the MAU's

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

as though it were powered down or not connected.
The MAU MAY return other(1) value for the
rpMauJabberState and rpMauMediaAvailable objects

state will remove power from the AUI.
Setting this variable to the value reset(6)

Setting this variable to the value

The value other(1) is returned if the

The value unknown(2) is returned when the MAU's
true state is unknown; for example, when it is

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.
Flick Standards Track [Page 19]
RFC 3636 802.3 MAU MIB September 2003
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

notAvailable(4). The value notAvailable(4)
takes precedence over the value remoteFault(5).
Any MAU that implements management of clause 37

Fault (RF1 and RF2) bit values for Offline to

Auto-Negotiation Error to autoNegError(11)."

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 which 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 which has
the capability to be only 10BASE-T would have a
value of 512 (2**9). In contrast, a MAU which
supports both 10Base-T (full duplex) and
100BASE-TX (full duplex) would have a value of
((2**11) + (2**16)) or 67584.
The powers of 2 assigned to the capabilities are
these:

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.
Flick Standards Track [Page 32]
RFC 3636 802.3 MAU MIB September 2003
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."

9. 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.
Flick Standards Track [Page 58]
RFC 3636 802.3 MAU MIB September 2003
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.
