Duplex

Select the desired duplex level for this physical port. You can set this field to Auto to have the HMC select the duplex level automatically, or you can set this field to a specific duplex level to have the HMC attempt to negotiate the selected duplex level. If the HMC cannot negotiate the selected duplex level, the HMC automatically selects a duplex level that the physical port can support.

Valid values are Auto, Full, and Half-duplex.

If you set this field to Auto, you must also set the Speed field to Auto.
