MIB: EtherLike-MIB

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.
