          DESCRIPTION "********* THIS OBJECT IS DEPRECATED **********

                      A value that uniquely identifies the set of
                      possible IEEE 802.3 types that the MAU could be.
                      The value is a sum which 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 which has
                      the capability to be only 10BASE-T would have a
                      value of 512 (2**9).  In contrast, a MAU which
                      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

          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

                      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

                      A value that uniquely identifies the set of
                      capabilities of the local auto-negotiation

                      of this interface, 2 raised to the power noted

                      below is added to the sum. For example, an
                      interface which has the capability to support
                      only 100Base-TX half duplex would have a value
                      of 32768 (2**15).  In contrast, an interface
                      which supports both 100Base-TX half duplex and
                      and 100Base-TX full duplex would have a value of
                      98304 ((2**15) + (2**16)).

8.  Security Considerations

   There are a number of management objects defined in this MIB that
   have a MAX-ACCESS clause of read-write. Setting these objects can
   have a serious effect on the operation of the network, including:

        enabling or disabling a MAU
        changing a MAU's default type
        enabling, disabling or restarting autonegotiation
        modifying the capabilities that a MAU advertizes during
            autonegotiation.

   Such objects may be considered sensitive or vulnerable in some
   network environments.  The support for SET operations in a non-secure
   environment without proper protection can have a negative effect on
   network operations.

   SNMPv1 by itself is such an insecure environment.  Even if the
   network itself is secure (for example by using IPSec), even then,
   there is no control as to who on the secure network is allowed to
   access and GET/SET (read/change/create/delete) the objects in this
   MIB.

   It is recommended that the implementers consider the security
   features as provided by the SNMPv3 framework.  Specifically, the use
   of the User-based Security Model RFC 2574 [12] and the View-based
   Access Control Model RFC 2575 [15] is recommended.

Top      Up      ToC       Page 52 
   It is then a customer/user responsibility to ensure that the SNMP
   entity giving access to an instance of this MIB, is properly
   configured to give access to those objects only to those principals
   (users) that have legitimate rights to access them.

Appendix

   Change Log

   This section enumerates the changes made to RFC 2239 to produce this
   document.

      (1)   The MODULE-IDENTITY has been updated to reflect the changes
            in the MIB.

      (2)   OBJECT-IDENTITY definitions have been added for gigabit MAU
            types.

      (3)   The ifMauTypeList, ifMauAutoNegCapability,
            ifMauAutoNegCapAdvertised and ifMauAutoNegCapReceived
            objects have been deprecated and replaced by
            ifMauTypeListBits, ifMauAutoNegCapabilityBits,
            ifMauAutoNegCapAdvertisedBits and
            ifMauAutoNegCapReceivedBits.

      (4)   Two new objects, ifMauAutoNegRemoteFaultAdvertised and
            ifMauAutoNegRemoteFaultReceived have been added.

      (5)   Enumerations for 'offline' and 'autoNegError' have been
            added for the rpMauMediaAvailable and ifMauMediaAvailable
            objects.

      (6)   The broadMauBasicTable and mauBroadBasic object group have
            been deprecated.

      (7)   The mauIfGrp100Mbs and mauIfGrpAutoNeg object groups have
            been deprecated and replaced by mauIfGrpHighCapacity and
            mauIfGrpAutoNeg2.

      (8)   A new object group, mauIfGrpAutoNeg1000Mbps, has been added.

      (9)   The mauModIfCompl and mauModRpCompl compliances have been
            deprecated and replaced by mauModIfCompl2 and
            mauModRpCompl2.

      (10)  Added section on relationship to RFC 2239.

      (11)  Updated the SNMP Network Management Framework boilerplate.

Top      Up      ToC       Page 55 
      (12)  Refer to the Interfaces MIB, rather than the interfaces
            group of MIB-II.

      (13)  Updated references to refer to latest edition of IEEE 802.3.

      (14)  An intellectual property notice was added, as required by
            RFC 2026.
