      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.
                  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; it 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."

                  agents and MAUs that do not implement software

                  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; it 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

                  This object represents the

                  Auto-Negotiation is not enabled or is not

                  force the MAU into the specified operating mode.

                  If Auto-Negotiation is implemented and enabled
                  for this MAU, the operational type of the MAU
                  is determined by Auto-Negotiation, and the value

                   A GET operation returns the current mode of operation

                   a SET operation is not allowed and a GET operation maps 
                   to the variable FEC enabled in Clause 74.
