sDot3StatsDuplexStatus
Module: GBNDeviceSWAPI-MIB
OID (symbolic): GBNDeviceSWAPI-MIB::sDot3StatsDuplexStatus
OID (numeric): 1.3.6.1.4.1.13464.1.2.2.2.9.1.2.1.19
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
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.
What is sDot3StatsDuplexStatus?
Reports the MAC's actual current duplex mode, which is controlled indirectly via the MAU MIB objects (sIfMauDefaultType or auto-negotiation) - a quick sanity check that a port negotiated full duplex when it was supposed to.
