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 and the
media transmitter to idle. 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. The MAU may return
other(1) value for the mauJabber 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."REFERENCE"Reference IEEE 802.3 MAU Mgt, 20.2.3.2,

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.
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.
The value invalidSignal(6) indicates that an
invalid signal has been received from the other
