Modifying Configuration Parameters

■

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.

■

■

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.

■

■

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.

■

■

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.
