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:
RFC 2239 [18].
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 [17].

2. The SNMP Network Management Framework
The SNMP Network Management Framework presently consists of six major
components. They are:
o the overall architecture, described in RFC 2271 [12].
o the SMI, described in RFC 1902 [7], - the mechanisms used for
describing and naming objects for the purpose of management.
o the MIB-II, STD 17, RFC 1213 [5], - the core set of managed
objects for the Internet suite of protocols.
o the protocol, RFC 1157 [11] and/or RFC 1905 [10] and/or
RFC 2272 [13] -- the protocol for accessing managed
information.
o the user-based security model defined in RFC 2274 [15].
o the view-based access control model defined in RFC 2275 [16].
Textual conventions are defined in RFC 1903 [8], and conformance
statements are defined in RFC 1904 [9]. Common applications are
defined in RFC 2273 [14].
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
This memo specifies a MIB module that is compliant to the SNMPv2 SMI.
A semantically identical MIB conforming to the SNMPv1 SMI can be
produced through the appropriate translation.
2.1. 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) [4]
defined in the SMI. In particular, each 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. Change Log
Smith, et. al. Expires November 1998 [Page 3]
Internet Draft 802.3 MAU MIB May 1998
This section enumerates the changes made to RFC 2239 to produce this
document.
(1) The MODULE-IDENTITY has been updated to reflect the changes
in the MIB.
(2) OBJECT-IDENTITY definitions have been added for gigabit MAU
types.
(3) The ifMauTypeList, ifMauAutoNegCapability,
ifMauAutoNegCapAdvertised and ifMauAutoNegCapReceived
objects have been deprecated and replaced by
ifMauTypeListBits, ifMauAutoNegCapabilityBits,
ifMauAutoNegCapAdvertisedBits and
ifMauAutoNegCapReceivedBits.
(4) Two new objects, ifMauAutoNegRemoteFaultAdvertised and
ifMauAutoNegRemoteFaultReceived have been added.
(5) Enumerations for 'offline' and 'autoNegError' have been
added for the rpMauMediaAvailable and ifMauMediaAvailable
objects.
(6) The mauIfGrp100Mbs and mauIfGrpAutoNeg object groups have
been deprecated and replaced by mauIfGrpHighCapacity and
mauIfGrpAutoNeg2.
(7) A new object group, mauIfGrpAutoNeg1000Mbps, has been added.
(8) The mauModIfCompl compliance has been deprecated and
replaced by mauModIfCompl2.
(9) Added section on relationship to RFC 2239.
(10) Updated the SNMP Network Management Framework boilerplate.
(11) Refer to the Interfaces MIB, rather than the interfaces
group of MIB-II.
(12) An intellectual property notice was added, as required by
RFC 2026.
4. Overview
4.1. Relationship to RFC 2239
This MIB is intended to be a superset of that defined by RFC 2239
Smith, et. al. Expires November 1998 [Page 4]
Internet Draft 802.3 MAU MIB May 1998
[18], which will go to historic status. This MIB includes all of the
objects contained in that MIB, plus several new ones which provide
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 objects provide
management support for:
o management of 1000 Mb/s interface devices
o management of PAUSE negotiation
o management of remote fault status
4.2. Relationship to RFC 1515
RFC 2239 was a replacement for RFC 1515 [19], which is now historic.
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
4.3. MAU Management
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 [1] and [2]. 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, 100 & 1000 Mb/s Medium Attachment Units (MAUs)",
and Annex 30A, "GDMO Specifications for 802.3 managed objects" of
IEEE Draft P802.3z/D4.2 [2]. That specification includes definitions
for 10Mb/s, 100Mb/s and 1000Mb/s devices. This specification is
intended to serve the same purpose: to provide for management of all
types of Ethernet/802.3 MAUs.
4.4. Relationship to Other MIBs
It is assumed that an agent implementing this MIB will also implement
(at least) the 'system' group defined in MIB-II [5]. The following
Smith, et. al. Expires November 1998 [Page 5]
Internet Draft 802.3 MAU MIB May 1998
sections identify other MIBs that such an agent should implement.
4.4.1. Relationship to the Interfaces MIB.
The sections of this document that define interface MAU-related
objects specify an extension to the Interfaces MIB [6]. An agent
implementing these interface-MAU related objects MUST also implement
the relevant groups of 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 expected that an agent implementing the interface-MAU related
objects in this MIB will also implement the Ethernet-like Interfaces
MIB, [20].
(Note that repeater ports are not represented as interfaces in the
Interface MIB.)
4.4.2. 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
[3]. An agent implementing these repeater-MAU related objects MUST
also implement 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.
4.5. 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.

be implemented as a read-only object by those
agents and MAUs that do not implement software
control of the MAU state. Some agents may not
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.
Smith, et. al. Expires November 1998 [Page 15]
Internet Draft 802.3 MAU MIB May 1998
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
shutdown state."

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 6.
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 [2]. 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.
Smith, et. al. Expires November 1998 [Page 17]
Internet Draft 802.3 MAU MIB May 1998
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 802.3u-1995 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 other(1) is returned if the MAU is in
a state other than one of the states 2 through

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
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

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

return the value reset (6).

DESCRIPTION "Setting this object to enabled(1) will cause
the interface which has the auto-negotiation
signaling ability to be enabled.
If the value of this object is disabled(2) then
the interface will act as it would if it had no
auto-negotiation signaling. Under these
conditions, an IEEE 802.3 MAU will immediately
be forced to the state indicated by the value of
the object ifMauDefaultType.
NOTE TO IMPLEMENTORS: 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 the ifMauDefaultType
object, rather than continuing to operate at the
value earlier determined by the auto-negotiation
function."

DESCRIPTION "********* THIS OBJECT IS DEPRECATED **********
A value that uniquely identifies the set of
capabilities of the local auto-negotiation
entity. The value is a sum which initially
Smith, et. al. Expires November 1998 [Page 33]
Internet Draft 802.3 MAU MIB May 1998
takes the value zero. Then, for each capability
of this interface, 2 raised to the power noted
below is added to the sum. For example, an
interface which has the capability to support
only 100Base-TX half duplex would have a value
of 32768 (2**15). In contrast, an interface
which supports both 100Base-TX half duplex and
and 100Base-TX full duplex would have a value of
98304 ((2**15) + (2**16)).
The powers of 2 assigned to the capabilities are
these:
Power Capability
0 other or unknown
(1-9) (reserved)
10 10BASE-T half duplex mode
11 10BASE-T full duplex mode
12 (reserved)

9. Security Considerations
Certain management information defined in this MIB may be considered
sensitive in some network environments. Therefore, authentication of
received SNMP requests and controlled access to management
information should be employed in such environments. The method for
this authentication is a function of the SNMP Administrative
Framework, and has not been expanded by this MIB.
Several objects in this MIB allow write access. Setting these
objects can have a serious effect on the operation of the network,
including enabling or disabling a MAU, changing a MAU's default type,
enabling, disabling or restarting autonegotiation, or modifying the
capabilities that a MAU advertizes during autonegotiation. It is
recommended that implementers seriously consider whether set
operations should be allowed without providing, at a minimum,
authentication of request origin.
