Interface Control attribute
The Interface Control attribute is a structure consisting of Forced Interface Speed and
Control Bits.
If the autonegotiate bit is 0, the Forced Interface Speed bits indicate the speed at which the
interface operates. Speed is specified in megabits per second; for example, for 10 Mbps
EtherNet, the Interface Speed is 10. Interfaces not supporting the requested speed return
0x09 (Invalid Attribute Value). If autonegotiation is enabled, attempting to set the Forced
Interface Speed results in a response of 0x0C (Object State Conflict).
Control Bits operate as follows:
Bit(s)

Definition
0 Autonegotiate 0 = 802.3 link autonegotiation is disabled.
1 = autonegotiation is enabled.
If autonegotiation is disabled, the device uses the settings indicat-
ed by the Forced Duplex Mode and Forced Interface Speed bits.
1 Forced Duplex Mode If the Autonegotiate bit is 0, the Forced Duplex Mode bit indicates
whether the interface operates in full or half duplex mode.
0 = half duplex.
1 = full duplex.
Interfaces not supporting the requested duplex return 0x09 (Invalid
Attribute Value). If autonegotiation is enabled, attempting to set the
Forced Duplex Mode bits results in a response of 0x0C (Object
State Conflict).
