    REVISION    "200704210000Z"  -- April 21, 2007

    DESCRIPTION "Updated to reference IANA maintaned textual

                conventions for MAU types, Media Availability state,

                Auto Negotiation capabilities, and jack types,

    REVISION    "200309190000Z"  -- September 19, 2003

    DESCRIPTION "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

                - Deprecated mauModIfCompl2 and replaced it

                  with mauModIfCompl3, which includes the new

                  object group

                 This version published as RFC 3636."

                   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."

                   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

       DESCRIPTION "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."
