linux 下查看网卡工作速率

Ethtool是用于查询及设置网卡参数的命令。

概要：

ethtool ethX //查询ethX网口基本设置

ethtool –h //显示ethtool的命令帮助(help)

ethtool –i ethX //查询ethX网口的相关信息

ethtool –d ethX //查询ethX网口注册性信息

ethtool –r ethX //重置ethX网口到自适应模式

ethtool –S ethX //查询ethX网口收发包统计

ethtool –s ethX [speed 10|100|1000] //设置网口速率10/100/1000M

[duplex half|full] //设置网口半/全双工

[autoneg on|off] //设置网口是否自协商

使用ethtool,结果如下：

[root@hadoop009 var]# ethtool  em1
