4.2 Driver Settings
PCIe-PoE354at and PCIe-352at 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.
4.2.1 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 9.5 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.
