Switch Configuration. Allows configuring of the connected switch for the network adapters.
NOTE: Switch Configuration only applies to blade configurations.
• SW_Config_10G (default). Sets the switch speed to 10 Gbit/s.
• SW_Config_1G. Sets the switch speed to 1 Gbit/s.
Speed & Duplex. The Speed & Duplex property sets the connection speed and mode to that of the network. Note that Full-
Duplex mode allows the adapter to transmit and receive network data simultaneously.
• 10 Mb Full. Sets the speed at 10 Mbit/s and the mode to Full-Duplex.
• 10 Mb Half. Sets the speed at 10 Mbit/s and the mode to Half-Duplex.
• 100 Mb Full. Sets the speed at 100 Mbit/s and the mode to Full-Duplex.
• 100 Mb Half. Sets the speed at 100 Mbit/s and the mode to Half-Duplex.
• 1 Gb Full. Sets the speed at 1000 Mb Full-Duplex mode only. Not available for 1 Gb ports.
• 2.5 Gb Full. Sets the speed at 2.5
• 10 GB Full. Sets the speed to 10 Gbit/s and the mode to Full-Duplex. Not available for 1 Gb ports.
• Auto (default). Sets the speed and mode for optimum network connection (recommended).
NOTES:
• Auto is the recommended setting. This setting allows the network adapter to dynamically detect the line speed
of the network. Whenever the network capability changes, the network adapter automatically detects and
adjusts to the new line speed and duplex mode. A speed of 1 Gbit/s is enabled by selecting Auto, when that
speed is supported.
• 1 Gb Full Auto must be attached to a link partner that is also capable of a 1 Gb connection. Since the connection
is limited to a 1 Gb connection only, the Ethernet@Wirespeed feature will be disabled. If the link partner
supports a 1 Gb connection only, the Wake on LAN feature may not work. Additionally, management traffic
(IPMI or UMP) in the absence of an operating system may also be affected.
• 10 Mb Half and 100 Mb Half settings force the network adapter to connect to the network in Half-Duplex mode.
Note that the network adapter may not function if the network is not configured to operate at the same mode.
• 10 Mb Full and 100 Mb Full settings force the network adapter to connect to the network in Full-Duplex mode.
The network adapter may not function if the network is not configured to operate at the same mode.
Speed & Duplex (SerDes).
• 1 Gb Full. Forces the speed to 1 Gb Full based on a matching setting for its link partner.
• Auto (default). Sets the speed to auto-negotiate with its link partner at the highest matching speed.
• Auto with 1Gb Fallback Full. Sets the speed to auto-negotiate with its link partner, but if the attached link partner is
forced at 1 Gbit/s, it will fall back to this mode.
• Hardware Default. Sets the speed to negotiate according to the setting specified by the manufacturer (see
manufacturer documentation for more information).
NOTE: The following properties pertain to Windows Vista operating systems.
TCP/UDP Checksum Offload (IPv4). Allows configuring checksum offload for the IPv4 protocol.
• Disable. Disables checksum offload.
• Rx Enabled. Enables receive TCP/IP/UDP checksum offload.
