今天搞网卡千兆,花费一天时间,不总结对不起自己,以下是ethtool的一些总结

ethtool -s speed 1000 duplex full autoneg off  ;强制千兆双工
ethtool eth0                                   ;查看eth0状态
ethtool -s eth0 advertise 0x020         ;设置为全双工1000M
可以设置的advertise参数:
advertise的值:
0x001    10 Half
0x002    10 Full
0x004    100 Half
0x008    100 Full
0x010    1000 Half(not supported by IEEE standards)
0x020    1000 Full
0x8000   2500 Full(not supported by IEEE standards)
0x800    10000 Full
0x03F    Auto
