■ Full Duplex Enabled
When link negotiation is unchecked, this parameter sets the duplex mode.
You can select either half-duplex or full-duplex operation.
■ When checked, full-duplex signaling is used (default).
■ When unchecked, half-duplex operation is used.
■ Tx Flow Control
■ When Tx flow control is checked and link negotiation is enabled, the
NIC negotiates 802.3x transmit flow control with the device at the
other end of the link. If 802.3x flow control is supported by the other
device, Tx flow control is enabled.
■ When Tx flow control is checked and link negotiation is disabled, you
must check Full Duplex Enabled in order for Tx flow control to work
properly. Tx flow control will not function under half duplex operation.
■ When Tx flow control is unchecked (default), or when Full Duplex
Enabled is unchecked, transmit flow control is disabled.
■ Rx Flow Control
■ When Rx flow control is checked (default) and link negotiation is
enabled, the NIC negotiates 802.3x receive flow control with the device
at the other end of the link. If 802.3x flow control is supported by the
other device, Rx flow control is enabled.
■ When Rx flow control is checked and link negotiation is disabled, you
must check Full Duplex Enabled in order for Rx flow control to work
properly. Rx flow control will not function under half duplex operation.
■ When unchecked, or when Full Duplex Enabled is unchecked, receive
flow control is disabled.
■ Port Link Speed
■ When link negotiation is disabled, this parameter sets the port link
speed. You can select link speed to be either 10Mbps, 100Mbps, or
1Gbps. When the port link is connected, the selected link speed is
indicated to the right of this field.
NOTE: When link negotiation is on, the user-configured link speed and
duplex settings are ignored in favor of automatically determined settings.
