• Link negotiation
— When checked (default), 802.3-1999 compliant Gigabit Ethernet link
negotiation is enabled. All Netfinity Gigabit Ethernet Adapters use link
negotiation by default.
— When unchecked, link negotiation is disabled and only link signal
detection is used. Use this setting when connecting to Ethernet equipment
that does not support link negotiation, or if there is a problem establishing a
link between the adapter and the connecting device. Unless otherwise
specified, the default signaling speed is 1Gbps.
When link negotiation is disabled, be sure that the connecting device uses
the same duplex and speed settings.
Note: When link negotiation is on, the user-configured link speed and
duplex settings are ignored in favor of automatically determined
settings.
• 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
adapter will negotiate 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 will be 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 adapter will negotiate 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 will be 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.
