                       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 obtain 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 8-bit wide
                       group encoding schemes.

                       Discontinuities in the value of this counter can
                       occur at re-initialization of the management

                       layer for speeds above 10 Mb/s will cause the
