有线网口ETH

  1. F305L具备两路千兆RJ45网络接口,网线可采用4芯和8芯网线,通过ethtool (其中一路为核心模块自带千兆网络,另外一路为PCIex1 扩展而来采用的是Realtek RTL8111芯片)

  1. F305L 2个网口支持NTP, 但不支持PTP即IEEE.1588协 议(方竹科技提供其他型号载板可支持PTP协议)

  2. 通过如下一些命令进行有限网络的带宽与丢包测试,详情如下:

测试工具:iperf 或 iperf3(Windows or Linux)

$sudo apt-get install iperf

PC 电 脑配置IP: 192.168.1.195

F305L机器配置IP:192.168.1.159

如下测试网络带宽,稳定运行带宽可达940Mbits/sec

PC电脑作为服务端运行:iperf -s -i 2 -w 2m (IP: 192.168.1.2) ../_images/eth.01.png

F305L作为设备端运行:iperf -c 192.168.1.2-i 2 -w 2m -t 60 ../_images/eth.02.png

F305L作为服务端运行:iperf -s -i 2 -w 2m (IP: 192.168.1.159) ../_images/eth.03.png

PC电脑作为设备端运行:iperf -c 192.168.1.159-i 2 -w 2m -t 60 ../_images/eth.04.png

如下可测试网络抖动、丢包率 F305L作为服务端运行:iperf -s -u -i 2 ../_images/eth.05.png

PC电脑作为设备端运行:iperf -c 192.168.1.159 -i 2 -w 2m -u -b 200m -t 60 ../_images/eth.06.png
