    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.

                 This version published as RFC 3635."

                interface that are not an integral number of
                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
                that amount of time could be less than a
                management station's poll cycle time, in order
                to avoid a loss of information, a management
                station is advised to poll the
                dot3HCStatsAlignmentErrors object for 10 Gb/s
                or faster interfaces.

                Discontinuities in the value of this counter can

                count does not include frames received with

                Note:  Coding errors detected by the physical

                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

    DESCRIPTION "A count of frames for which reception on a
                particular interface fails due to an internal
                MAC sublayer receive error. A frame is only
                counted by an instance of this object if it is
                not counted by the corresponding instance of
                either the dot3StatsFrameTooLongs object, the
                dot3StatsAlignmentErrors object, or the
                dot3StatsFCSErrors object.

                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 receive errors
                on a particular interface that are not
                otherwise counted.

                This counter is a 64 bit version of
                dot3StatsInternalMacReceiveErrors.  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

    DESCRIPTION "For an interface operating at 100 Mb/s, the
                number of times there was an invalid data symbol
                when a valid carrier was present.

                For an interface operating in half-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 slotTime, and
                during which there was at least one occurrence
                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.

    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

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
