其实查看网卡兆数的方法十分简单,只要使用ethtool命令就可以了。首先我们需要了解到ethtool是Linux下用于查询及设置网卡参数的命令,现在就开始测试一下吧。

输入指令如下所示:

root@imx6qdlsolo:~# ethtool eth0

Settings for eth0:

   Supported ports: [ TP MII ]

   Supported link modes:  10baseT/Half 10baseT/Full

                            100baseT/Half100baseT/Full

                            1000baseT/Full

   Supported pause frame use: Symmetric

   Supports auto-negotiation: Yes

   Advertised link modes: 10baseT/Half 10baseT/Full

                           100baseT/Half100baseT/Full

                            1000baseT/Full

   Advertised pause frame use: Symmetric

   Advertised auto-negotiation: Yes

   Link partner advertised link modes: 10baseT/Half 10baseT/Full

                                        100baseT/Half 100baseT/Full

                                        1000baseT/Full

   Link partner advertised pause frame use: Symmetric

   Link partner advertised auto-negotiation: Yes

   Speed: 1000Mb/s

   Duplex: Full

   Port: MII

   PHYAD: 1

   Transceiver: external

   Auto-negotiation: on

   Supports Wake-on: g

   Wake-on: d

   Link detected: yes

root@imx6qdlsolo:~#

详细参数参考:(//后面是注释,是原文的译文)

ethtool ethX /

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

[port tp|aui|bnc|mii]\ //设置网口类型

这样通过这个指令,我们成功地得到了所需的相关参数,一起来试一下吧。
