recommended selection is Auto and it is the default setting. To disable Flow Control, select Disable from the Value list on the Advanced tab.

oAuto. (Default) Auto detect flow control

oDisable. PAUSE frame receipt and transmission is disabled

oTx PAUSE. PAUSE frame transmission is enabled

oRx PAUSE. PAUSE frame receipt is enabled

Rx/Tx PAUSE. PAUSE frame receipt and transmission is enabled

NOTE: User control of Flow Control parameter is not available for NC71xx adapters.

•Link Speed & Duplex. Allows the user to set the connection speed to the network and mode. Full- Duplex Mode allows the adapter to transmit and receive network data simultaneously. This property is not available for NC310F and NC61xx adapters through the Microsoft® User Interface.

oDefault = Auto Detect

oRange = NC340x and NC71xx Adapters: Auto Detect; 10Mbps/Half-Duplex; 10Mbps/Full- Duplex; 100Mbps/Half-Duplex; 100Mbps/Full-Duplex; 1000 Mbps/Full-Duplex

•Locally Administered Address. Specifies the user-defined MAC Address of the adapter, which overrides the burned-in MAC Address. This box is disabled if the selected adapter has been teamed.

oDefault = Not Present

oRange = Value; Not Present

•Number of Receive Descriptors. Specifies the number of buffers used by the driver when copying data to the protocol memory. In high network load situations, increasing receive descriptors can increase performance. The tradeoff is that this also increases the amount of system memory used by the driver. If too few receive buffers are used, performance suffers. If too many receive buffers are used, the driver unnecessarily consumes memory resources.
