Configuration and diagnostics 15
• IPv4 Checksum Offload. Describes whether the device enabled or disabled the calculation of IPv4
checksums.
o Tx/Rx enabled (default)
o None
o Rx enabled
o Tx enabled
• Large Send Offload. Normally, the TCP segmentation is performed by the protocol stack. By
enabling the Large Send Offload property, the TCP segmentation can be performed by the Gigabit
Ethernet Adapter. To enable the Large Send Offload property, select Enable from the Value drop-
down menu on the Advanced tab.
o Disable. Disables large send offloading
o Enable. Enables large send offloading
• IPv4 Large Send Offload. Describes whether the device enabled or disabled the segmentation of
large TCP packets over IPv4 for large send offload.
o Default = Enabled
o Range = Disabled; Enabled
• 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.
o Default = Not Present
o Range = Value; Not Present
• Speed & Duplex. The Speed & Duplex property 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 1 Gb Full Auto. Sets the speed to 1 Gbps and mode to Full-Duplex
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 1000 Mb Full. Sets the speed to 1000 Mbps and mode to Full-Duplex
o 1000 Mb Half. Sets the speed to 1000 Mbps and mode to Half-Duplex
o 2500 Mb. To achieve speeds of 2.5 Gbps, update to the latest firmware and then set the link
partner (switch or hub) and the device port to Auto/Auto. This speed is only achievable if the link
partner is capable of 2.5 Gbps.
o Auto. (Default) Sets the speed and mode for optimum network connection (recommended)
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.
