This object contains an OBJECT IDENTIFIER

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."

DESCRIPTION "The current mode of operation of the MAC
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."
