The full-duplex setting is not required by the IEEE 802.3ab 1000 Base-T standard. In order to be compliant with the standard, devices must be able to auto-negotiate to 1000 full-duplex when the port is configured to “auto”. If your device does not operate at 1000 full-duplex with the switch port set to “auto”, check your device driver and cable, or contact technical support for your product(s).
