如何查看SAIL-IMX6網(wǎng)卡是百兆還是千兆

其實查看網(wǎng)卡兆數(shù)的方法十分簡單，只要使用ethtool命令就可以了。首先我們需要了解到ethtool是Linux下用于查詢及設(shè)置網(wǎng)卡參數(shù)的命令，現(xiàn)在就開始測試一下吧。

輸入指令如下所示：

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:~#

詳細(xì)參數(shù)參考：（//后面是注釋，是原文的譯文）

ethtool ethX /

ethtool –h //顯示ethtool的命令幫助(help)

ethtool –i ethX //查詢ethX網(wǎng)口的相關(guān)信息

ethtool –d ethX //查詢ethX網(wǎng)口注冊性信息

ethtool –r ethX //重置ethX網(wǎng)口到自適應(yīng)模式

ethtool –S ethX //查詢ethX網(wǎng)口收發(fā)包統(tǒng)計

ethtool –s ethX [speed 10|100|1000]\ //設(shè)置網(wǎng)口速率10/100/1000M

[duplex half|full]\ //設(shè)置網(wǎng)口半/全雙工

[autoneg on|off]\ //設(shè)置網(wǎng)口是否自協(xié)商

[port tp|aui|bnc|mii]\ //設(shè)置網(wǎng)口類型

這樣通過這個指令，我們成功地得到了所需的相關(guān)參數(shù)，一起來試一下吧。
