3.3 Configuring Devices for Win XP/Vista/7
PCIe-1672PC and PCIe-1674PC offer the Gigabit Ethernet connectivity via Intel®
i350 GbE controller. When connecting to a high-speed PoE device, such as a GigE
camera, you can adjust some driver settings to have better transmission throughput
and connection stability.
In this section, we’ll discuss these settings. You can refer to the information to fine
tune your system.
3.3.1 Jumbo Frame
Jumbo frames are Ethernet frames with more than 1500 bytes of payload. By
increasing the payload size, a certain large amount of data can be transferred with
less interrupts generated, which reduces the CPU utilization and increases overall
data throughput. Intel® i350 GbE controller supports jumbo frame size of up to 9
Kbytes. When you connecting an Ethernet device with high date rate (e.x. a Gigabit
Ethernet camera), enabling jumbo frame feature is highly recommended.
After installing the driver for Intel® i350 GbE controller, you can change the jumbo
frame settings by following the steps listed below.
