Ethernet Basic Configuration

Ethernet Basic Configuration

Parameters


Parameter Description
Permanent Ethernet Address Specifies the fixed Ethernet address encoded in the hardware.
This field is for information only and cannot be changed.
Current Ethernet Address Specifies the Ethernet address currently being used.
The Ethernet interface then uses the Current Ethernet Address instead of the Permanent Ethernet Address. Format of Ethernet Address must be XX:XX:XX:XX:XX:XX.
Speed/Duplex Settings Configure Ethernet speed/duplex settings.
For systems equipped with Gigabit Ethernet PHY (physical layer transceivers), the "Autonegotiate for 1000 Mbps" selection is available. Otherwise, only the 100/10 Mbps selections are available.
Driver Optimization Allows Ethernet driver optimization by adjusting the Ethernet driver operating parameters to suit different needs.
The four sets of driver optimization profiles are as follows:

Throughput - This profile maximizes the amount of network traffic sent and received.

CPU Utilization - This profile is optimized to reduce the amount of CPU time spent in processing network traffic. CPU Utilization is the recommended and default setting.

Multimedia - This profile reduces the time spent per network interrupt to allow time-critical media devices to be serviced.

Custom - This option lets you create your own profile.

Click the icon to open the Advanced Configuration page for a detailed view of the ethernet driver operating parameters. Only the Custom option lets you change these values.
ASF Enable or disable ASF (Alert Standard Format) feature.
ASF is an industry specification that defines alerting capability in both operating system-present and operating system-absent environments.

Remote Wakeup Enable or disable Ethernet remote wakeup capability.
Remote Wakeup allows the user to turn on systems across the network from a remote location. For example, a network administrator can use Remote Wakeup to perform after-hours maintenance on a system without requiring a technician to be physically present.

Checksum Offload Enable or disable Ethernet checksum offload feature.
Offloads increase the system performance by offloading TCP/IP's CPU-intensive tasks to hardware.

TCP Segmentation/Large Send Offload (transmit only) Enable or disables the TCP Large Send OffLoad feature.
When the feature is enabled, the operating system can utilize the Ethernet hardware capabilities to segment large TCP packets into smaller packets.
Note: This feature applies to packet transmission only.
Jumbo Frame Specify the Ethernet jumbo frame payload size.
Jumbo frame supports larger Ethernet packet sizes to reduce server overhead and increase throughput. Payload size of 1,500 means Jumbo Frame is disabled. Jumbo frame is supported only when the connection speed is 1000 Mbps.
802.1p (Prioritization) Enable or disable Ethernet IEEE 802.1p support.
IEEE 802.1p allows frames to be grouped into priority classes.
802.1Q (VLAN) Enable or disables VLAN support. A virtual LAN (VLAN) is a group of computers that function as if they were connected to the same network segment, even though they may not reside on the same set of physical subnetworks.

Buttons


Button Description
Apply Apply changes.
When you click Apply, the network interface is disabled and then enabled in order for the changes to take place. This might result in error messages from network applications.
