        STATUS      current
        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 does not increment when the
                    interface is operating at 10 Mb/s.

                    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

                    dot3HCStatsSymbolErrors object for 10 Gb/s
                    or faster interfaces.

                    Discontinuities in the value of this counter can
                    occur at re-initialization of the management
                    system, and at other times as indicated by the

                    entity.  'unknown' indicates that the current
                    duplex mode could not be determined.

                    Management control of the duplex mode is
                    accomplished through the MAU MIB.  When
                    an interface does not support autonegotiation,
                    or when autonegotiation is not enabled, the
                    duplex mode is controlled using
                    ifMauDefaultType.  When autonegotiation is
                    supported and enabled, duplex mode is controlled
                    using ifMauAutoNegAdvertisedBits.  In either
                    case, the currently operating duplex mode is
                    reflected both in this object and in ifMauType.

                    Note that this object provides redundant
                    information with ifMauType.  Normally, redundant
                    objects are discouraged.  However, in this
                    instance, it allows a management application to
                    determine the duplex status of an interface
                    without having to know every possible value of
                    ifMauType.  This was felt to be sufficiently
                    valuable to justify the redundancy."
