o None. Disables checksum offloading
o Rx TCP/IP Checksum. Enables receive TCP, IP, and UDP checksum offloading
o Tx TCP/IP Checksum. Enables transmit TCP, IP, and UDP checksum offloading
o Tx/Rx TCP/IP Checksum. (Default) Enables transmit and receive TCP, IP, and UDP checksum
offloading
• Ethernet@WireSpeed. The Ethernet@WireSpeed parameter enables a 1000Base-T Ethernet adapter
to establish a link at a lower speed when only two pairs of wires are available in the cable plant. By
default, this parameter is enabled. To disable the Ethernet@WireSpeed parameter, select Disable
from the Value list on the Advanced tab. This property is not supported on NC1020 and NC7761
adapters.
o Disable. Disables Ethernet@WireSpeed
o Enable. (Default) Enables Ethernet@WireSpeed
• Flow Control. The Flow Control property allows the user to enable or disable the receipt or
transmission of PAUSE frames. PAUSE frames enable the adapter and the switch to control the
transmit rate. The side that is receiving the PAUSE frame will momentarily stop transmitting. The
recommended selection is Auto and it is the default setting. To disable Flow Control, select Disable
from the Value list on the Advanced tab.
o Auto. (Default) Auto detect flow control
o Disable. PAUSE frame receipt and transmission is disabled
o Tx PAUSE. PAUSE frame transmission is enabled
o Rx PAUSE. PAUSE frame receipt is enabled
o Rx/Tx PAUSE. PAUSE frame receipt and transmission is enabled
• Speed & Duplex. The Speed & Duplex parameter allows the user to set the connection speed to the
network and mode. The Duplex Mode allows the adapter to transmit and receive network data
simultaneously. The adapter is set to Auto (optimum connection) by default. Set the speed and mode
as described below:
o 10 Mb Full. Sets the speed to 10 Mbps and mode to Full-Duplex
o 10 Mb Half. Sets the speed to 10 Mbps and mode to Half-Duplex
o 100 Mb Full. Sets the speed to 100 Mbps and mode to Full-Duplex
o 100 Mb Half. Sets the speed to 100 Mbps and mode to Half-Duplex
o Auto. (Default) Sets the speed and mode for optimum network connection (recommended). 1
Gbps speed is enabled by selecting Auto.
NOTE: Auto is the recommended selection. It allows the adapter to dynamically detect the line
speed and duplex mode of the network. Whenever the network capability changes, the
adapter will automatically detect and adjust to the new line speed and duplex mode.
The Half-Duplex selection forces the adapter to connect to the network in Half-Duplex mode.
The adapter may not function if the network is not configured to operate at the same mode.
The Full-Duplex selection forces the adapter to connect to the network in Full-Duplex mode. The
adapter may not function if the network is not configured to operate at the same mode.
• Wake Up Capabilities. The Wake Up Capabilities parameter allows the user to set the adapter to
wake up from a low power mode when it receives a network wake up frame. Two wake up frames
are possible: Magic Packet and Wake Up Frame. By default, the adapter is set to Both. To choose
