LS1028A+千兆YT8614H通讯问题
YT8614H在一上电后能正常工作,ping命令操作正常,但是过一会后就会出现Destination Host Unreachable!64 bytes from 192.168.1.9: icmp_seq=263 ttl=64 time=0.708 ms64 bytes from 192.168.1.9: icmp_seq=264 ttl=64 time=0.564 ms

-----其中192.168.1.9是ubuntu的ip,192.168.1.120是swp0的地址
1.您确认一下网线链接是否牢固,您可以用ethtool swp0 查看链接是否稳定
2.主机一段您排查一下是否有防火墙设置的干扰
3.排查是否有其他网络设备与Ubuntu主机发生了IP地址冲突
