|
|

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

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."
