Note: In practice, a group will generally be
a field-replaceable unit (i.e., module, card,

enclosure, and the group number will correspond
to a number marked on the physical enclosure.

MAX-ACCESS read-write
STATUS current
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.
Smith, et al. Standards Track [Page 14]
RFC 2668 802.3 MAU MIB August 1999
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."

MAX-ACCESS read-only
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 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 [16]. 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.
Smith, et al. Standards Track [Page 16]
RFC 2668 802.3 MAU MIB August 1999
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).
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)."
