我在 Ubuntu 16.04 上添加了网卡(OneConnect 10Gb)并运行ethtool
命令,但输出显示speed and duplex unknown!.
知道如何修复这个问题吗?

答案1
您的接口是光纤,仅支持一种速度1000baseT/Full
,
Auto-negotiation: off
并且没有连接或检测到介质:Link detected: no
但您提到网卡是 10Gb。如果设置如您所写,该卡无法连接到另一侧的 10Gbps 节点。
如果您希望使用 1Gbps,请检查两端的光纤电缆、介质类型(多模/单模)和波长(SM:850/1300/1310 nm 或 MM:1550 nm)。
