Definition
Specifies whether the IEEE 802.3 communication interface is connected to an
active network:
0 = Inactive link.
1 = Active link.
Specification of the link status depends on the implementation.
Indicates the currently used duplex mode:
0 = Interface runs at half duplex.
1 = Interface runs at full duplex.
Note that the value of the half duplex / full duplex is undefined when the link
status bit memory is 0.
Specifies the status of the link autonegotiation:
0 = Ongoing autonegotiation.
1 = Autonegotiation and speed measurement failed. Use of default values for
speed and duplex.
2 = Autonegotiation failed, but speed was measured. Duplex was faulty.
3 = Speed and duplex negotiated successfully.
4 = Autonegotiation not attempted. Forced speed and duplex.
0 = Interface can automatically activate changes to link parameters (autonegoti-
ate, duplex mode, interface speed).
1 = Device requires that a reset service is output at its Identity object so that the
changes will become effective.
0 = Interface does not detect a local hardware fault.
1 = Local hardware fault detected.
Set to 0.
