debian set eth0 autoneg off speed 1000 duplex full: 无效参数

Question

我使用 debian 来处理我的事情，但是当我将速度配置为 1000 和双工满时，会发生错误

我使用的确切命令： ethtool -s eth0 autoneg off speed 1000 duplex full

  Cannot set new settings: Invalid argument
         not setting speed
         not setting duplex
         not setting autoneg
  Cannot set new settings: Invalid argument
         not setting speed
         not setting duplex
         not setting autoneg

这是我的 eth0 信息。

谁能告诉我哪里错了？

Answer 1

根据 IEEE 802.3-2002 规范的第 28D.5 节，自动协商是使用 1000BASE-T 的一项要求，因此您不能禁用 1000BASE-T 的自动协商。

尝试 -

sudo ethtool -s eth0 speed 1000 duplex full autoneg on

Answer 2

你试过了吗，

sudo ethtool -s eth0 speed 1000 duplex full autoneg off

但我支持 Zoredache 的评论，您可能不应该强制链接速度，除非没有它就无法工作，否则您应该将计算机设置为 autoneg，并确保网络端口设置为正确的速度。
