          Updated to include support for 10 Gb/s MAUs.

          This resulted in the following revisions:

          - Added OBJECT-IDENTITY definitions for

            10 gigabit MAU types

          - Added fiberLC jack type to JackType TC

          - Extended ifMauTypeListBits with bits for

            the 10 gigabit MAU types

          - Added enumerations to ifMauMediaAvailable,

            and updated its DESCRIPTION to reflect

            behaviour at 10 Gb/s

          - Added 64-bit version of ifMauFalseCarriers

            and added mauIfGrpHCStats object group to

            contain the new object

              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.

              carrier event.

              This counter increments only for MAUs of type

              dot3MauType100BaseT4, dot3MauType100BaseTX,

              dot3MauType100BaseFX, and all 1000Mbps types.

              For all other MAU types, this counter will

              always indicate zero.

              The approximate minimum time for rollover of

              this counter is 7.4 hours.

              Discontinuities in the value of this counter can

              occur at re-initialization of the management

              system and at other times, as indicated by the

              value of rptrMonitorPortLastChange.

              If the MAU type is unknown, the object identifier

              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

              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.

              ********* THIS OBJECT IS DEPRECATED **********

              This object has been deprecated in favour of

              ifMauTypeListBits.

              A value that uniquely identifies the set of

              possible IEEE 802.3 types that the MAU could be.

              The value is a sum that initially takes the

              value zero.  Then, for each type capability of

              this MAU, 2 raised to the power noted below is

              added to the sum.  For example, a MAU that has

              the capability to be only 10BASE-T would have a

              value of 512 (2**9).  In contrast, a MAU that

              supports both 10Base-T (full duplex) and

              100BASE-TX (full duplex) would have a value of

              ((2**11) + (2**16)), or 67584.

              The powers of 2 assigned to the capabilities are

              these:

              Power  Capability

                0      other or unknown

                1      AUI

                6      10BASE-FP

                7      10BASE-FB

                8      10BASE-FL duplex mode unknown

                9      10BROAD36

               10      10BASE-T  half duplex mode

               11      10BASE-T  full duplex mode

               12      10BASE-FL half duplex mode

               13      10BASE-FL full duplex mode

               14      100BASE-T4

              This object identifies the default

              administrative baseband MAU type to be used in

              conjunction with the operational MAU type

              denoted by ifMauType.

              The set of possible values for this object is

              the same as the set defined for the ifMauType

              object.

              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 operational type of the

              MAU.  In this case, a set to this object will

              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

              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 by ifMauType) correctly transitions to

              the value specified by this object, rather than

              continuing to operate at the value earlier

              determined by the auto-negotiation function.
