1、mii-tool 配置网络设备协商方式的工具;
1.1 mii-tool 介绍;

*J [YQR fh0mii-tool - view, manipulate media-independent interface status (mii-tool 是查看,管理介质的网络接口的状态)

%I;Ub3Lx$Dv0有时网卡需要配置协商方式 ,比如10/100/1000M的网卡半双工、全双工、自动协商的配置 。但大多数的网络设备是不用我们来修改协商,因为大多数网络设置接入的时候,都采用自动协商来解决相互通信的问题。不过自动协商也不是万能的,有时也会出现错误,比如丢包率比较高,这时就要我们来指定网卡的协商方式 。

mii-tool 就是能指定网卡的协商方式。下面我们说一说mii-tool的用法;

更改网络接口的协商方式,我们要用到-F选项,后面可以接 100baseT4, 100baseTx-FD, 100baseTx-HD, 10baseT-FD, 10baseT-HD等参数;51Testing软件测试网 dHVt}%b%Uo k

这个功能比较好办。就是ethtool 后面直接接网絽接口就行;比如下面的例子;
