   DESCRIPTION "The MIB module to describe generic objects for
               ethernet-like network interfaces.

               The following reference is used throughout this
               MIB module:

               [IEEE 802.3 Std] refers to:
                  IEEE Std 802.3, 2002 Edition: 'IEEE Standard
                  for Information technology -

                  between systems - Local and metropolitan
                  area networks - Specific requirements -

                  collision detection (CSMA/CD) access method
                  and physical layer specifications', as
                  amended by IEEE Std 802.3ae-2002:
                  'Amendment: Media Access Control (MAC)

                  2002.

               Of particular interest is Clause 30, '10 Mb/s,

   REVISION    "200309190000Z"  -- September 19, 2003
   DESCRIPTION "Updated to include support for 10 Gb/sec
                interfaces.  This resulted in the following
                revisions:

                - Updated dot3StatsAlignmentErrors and
                  dot3StatsSymbolErrors DESCRIPTIONs to
                  reflect behaviour at 10 Gb/s
                - Added dot3StatsRateControlAbility and
                  dot3RateControlStatus for management
                  of the Rate Control function in 10 Gb/s
                  WAN applications
                - Added 64-bit versions of all counters
                  that are used on high-speed ethernet
                  interfaces
                - Added object groups to contain the new
                  objects
                - Deprecated etherStatsBaseGroup and
                  split into etherStatsBaseGroup2 and
                  etherStatsHalfDuplexGroup, so that
                  interfaces which can only operate at
                  full-duplex do not need to implement
                  half-duplex-only statistics
                - Deprecated dot3Compliance and replaced
                  it with dot3Compliance2, which includes
                  the compliance information for the new
                  object groups

                In addition, the dot3Tests and dot3Errors
                object identities have been deprecated,
                since there is no longer a standard method
                for using them.

               octets in length and do not pass the FCS check.

               The count represented by an instance of this
               object is incremented when the alignmentError
               status is returned by the MAC service to the
               LLC (or other MAC user). Received frames for
               which multiple error conditions pertain are,
               according to the conventions of IEEE 802.3
               Layer Management, counted exclusively according
               to the error status presented to the LLC.

               This counter does not increment for group
               encoding schemes greater than 4 bits per group.

               For interfaces operating at 10 Gb/s, this
               counter can roll over in less than 5 minutes if
               it is incrementing at its maximum rate.  Since

               dot3HCStatsAlignmentErrors object for 10 Gb/s
               or faster interfaces.

               Discontinuities in the value of this counter can

               Note:  Coding errors detected by the physical

   DESCRIPTION "A count of frames for which transmission on a

               MAC sublayer transmit error. A frame is only
               counted by an instance of this object if it is

               The precise meaning of the count represented by
               an instance of this object is implementation-
               specific.  In particular, an instance of this
               object may represent a count of transmission
               errors on a particular interface that are not
               otherwise counted.

               For interfaces operating at 10 Gb/s, this
               counter can roll over in less than 5 minutes if

               dot3HCStatsInternalMacTransmitErrors object for
               10 Gb/s or faster interfaces.

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

               This object contains an OBJECT IDENTIFIER
               which identifies the chipset used to
               realize the interface. Ethernet-like
               interfaces are typically built out of
               several different chips. The MIB implementor
               is presented with a decision of which chip
               to identify via this object. The implementor
               should identify the chip which is usually
               called the Medium Access Control chip.
               If no such chip is easily identifiable,
               the implementor should identify the chip
               which actually gathers the transmit
               and receive statistics and error
               indications. This would allow a
               manager station to correlate the
               statistics and the chip generating
               them, giving it the ability to take
               into account any known anomalies
               in the chip.

               This object has been deprecated.  Implementation
               feedback indicates that it is of limited use for
               debugging network problems in the field, and
               the administrative overhead involved in
               maintaining a registry of chipset OIDs is not

               Management control of the duplex mode is
               accomplished through the MAU MIB.  When
               an interface does not support autonegotiation,

               of an event that causes the PHY to indicate
               'Data reception error' or 'carrier extend error'
               on the GMII.

               For an interface operating in full-duplex mode
               at 1000 Mb/s, the number of times the receiving
               media is non-idle (a carrier event) for a period
               of time equal to or greater than minFrameSize,
               and during which there was at least one
               occurrence of an event that causes the PHY to
               indicate 'Data reception error' on the GMII.

               For an interface operating at 10 Gb/s, the
               number of times the receiving media is non-idle
               (a carrier event) for a period of time equal to
               or greater than minFrameSize, and during which
               there was at least one occurrence of an event
               that causes the PHY to indicate 'Receive Error'
               on the XGMII.

               The count represented by an instance of this
               object is incremented at most once per carrier
               event, even if multiple symbol errors occur
               during the carrier event.  This count does
               not increment if a collision is present.

               This counter is a 64 bit version of
               dot3StatsSymbolErrors.  It should be used on
               interfaces operating at 10 Gb/s or faster.

               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 ifCounterDiscontinuityTime."

dot3TestTdr OBJECT-IDENTITY
   STATUS      deprecated
   DESCRIPTION "******** THIS IDENTITY IS DEPRECATED *******

               The Time-Domain Reflectometry (TDR) test is
               specific to ethernet-like interfaces of type
               10Base5 and 10Base2.  The TDR value may be
               useful in determining the approximate distance
               to a cable fault.  It is advisable to repeat
               this test to check for a consistent resulting
               TDR value, to verify that there is a fault.

               A TDR test returns as its result the time
               interval, measured in 10 MHz ticks or 100 nsec
               units, between the start of TDR test
               transmission and the subsequent detection of a
               collision or deassertion of carrier.  On
               successful completion of a TDR test, the result
               is stored as the value of an appropriate
               instance of an appropriate vendor specific MIB
               object, and the OBJECT IDENTIFIER of that
               instance is stored in the appropriate instance
               of the appropriate test result code object
               (thereby indicating where the result has been
               stored).

               This object identity has been deprecated, since
               the ifTestTable in the IF-MIB was deprecated,
               and there is no longer a standard mechanism for
               initiating an interface test.  This left no
               standard way of using this object identity."

-- Loopback Test

dot3TestLoopBack OBJECT-IDENTITY
   STATUS      deprecated
   DESCRIPTION "******** THIS IDENTITY IS DEPRECATED *******

               This test configures the MAC chip and executes
               an internal loopback test of memory, data paths,
               and the MAC chip logic.  This loopback test can
               only be executed if the interface is offline.
               Once the test has completed, the MAC chip should
               be reinitialized for network operation, but it
               should remain offline.

               If an error occurs during a test, the
               appropriate test result object will be set
               to indicate a failure.  The two OBJECT
               IDENTIFIER values dot3ErrorInitError and
               dot3ErrorLoopbackError may be used to provided
               more information as values for an appropriate
               test result code object.
