                    realize the interface. Ethernet-like

                    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

                    them, giving it the ability to take

                    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

                    without having to know every possible value of
                    ifMauType.  This was felt to be sufficiently
                    valuable to justify the redundancy."
