RFC 1515                     802.3 MAU MIB                September 1993


                    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
                    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.  The MAU may return
                    other(1) value for the mauJabber 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."

            ACCESS    read-only
            STATUS    mandatory
            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.

                    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
                    end of the link.  Both remoteFault(5) and
                    invalidSignal(6) apply only to MAUs of type
                    10BASE-FB."
