Abstract
This memo defines an portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it defines objects for managing 10 and 100 Mb/second
Medium Attachment Units (MAUs) based on IEEE Std 802.3 Section 30,
"10 & 100 Mb/s Management," October 26, 1995.
1. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework presently consists of three
major components. They are:
o the SMI, described in RFC 1902 [6] - 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, STD 15, RFC 1157 [10] and/or RFC 1905 [9] -
the protocol used for accessing managed information.
Textual conventions are defined in RFC 1903 [7], and conformance
statements are defined in RFC 1904 [8].
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
1.1. 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)
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.
2. Overview
2.1. Relationship to RFC 1515
This MIB is intended to be a superset of that defined by RFC 1515
[11], 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 100 Mb/s devices
o auto-negotiation on interface MAUs
o jack management
2.2. 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 Mb/s Medium Attachment Units (MAUs)", and
Annex 30A, "GDMO Specifications for 802.3 managed objects" of IEEE
Std 802.3u-1995. That specification includes definitions for both
10Mb/s and 100Mb/s devices, and is essentially a superset of the
10Mb/s definitions given by IEEE 802.3 Section 20. This
specification is intended to serve the same purpose: to provide for
management of both 10Mb/s and 100Mb/s MAUs.
2.3. 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
sections identify other MIBs that such an agent should implement.
2.3.1. Relationship to the MIB-II 'interfaces' group
The sections of this document that define interface MAU-related
objects specify an extension to the 'interfaces' group of MIB-II. An
agent implementing these interface-MAU related objects must also
implement the 'interfaces' group of MIB-II. 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, RFC 1650.
(Note that repeater ports are not represented as interfaces in the
sense of MIB-II's 'interfaces' group.)
2.3.2. 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
[4]. 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.
2.4. 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.

DESCRIPTION
"The current state of the MAU. This object may 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.
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."

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 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 100BASE-T4, 100BASE-TX and 100BASE-FX the
enumerations match the states within the
respective link integrity state diagrams, fig 23-
12 and 24-15 of sections 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.
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)."

MAU types are defined above. The assignment of
OBJECT IDENTIFIERs to new types of MAUs is managed
by the IANA. If the MAU type is unknown, the

syntactically valid object identifier, and any
conformant implementation of ASN.1 and the BER

This object represents the operational type of the
MAU, as determined by either (1) the result of the
auto-negotiation function or (2) if auto-
negotiation is not enabled or is not implemented
for this MAU, by the value of the object
ifMauDefaultType. In case (2), a set to the

DESCRIPTION
"The current state of the MAU. This object may 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.
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 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."

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 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 100BASE-T4, 100BASE-TX and 100BASE-FX the
enumerations match the states within the
respective link integrity state diagrams, fig 23-
12 and 24-15 of sections 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.
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)."

The set of possible values for this object is the

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

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

specified by this object, rather than continuing
to operate at the value earlier determined by the
auto-negotiation function."

6. 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.
