今天丸趣 TV 小編給大家分享一下 linux 如何檢查網(wǎng)卡是否正常的相關(guān)知識點，內(nèi)容詳細(xì)，邏輯清晰，相信大部分人都還太了解這方面的知識，所以分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后有所收獲，下面我們一起來了解一下吧。
linux 檢查網(wǎng)卡是否正常的方法：1、通過“mii-tool”指令查看網(wǎng)卡狀態(tài)；2、通過“network status”查看網(wǎng)絡(luò)狀態(tài)；3、通過“ifconfig -a”命令查看 linux 中所有網(wǎng)絡(luò)接口的信息；4、通過“ethtool”命令查詢網(wǎng)卡信息即可。
查看 Linux 下網(wǎng)卡狀態(tài)或 是否連接
1) 通過 mii-tool 指令
[root@localhost root]# mii-tool
eth0: negotiated 100baseTx-FD, link ok
eth2: no link或
[root@localhost root]# mii-tool -v
eth0: negotiated 100baseTx-FD, link ok
product info: vendor 00:50:43, model 2 rev 3
basic mode: autonegotiation enabled
basic status: autonegotiation complete, link ok
capabilities: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
advertising: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control
link partner: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
eth2: no link
product info: vendor 00:50:43, model 2 rev 3
basic mode: autonegotiation enabled
basic status: no link
capabilities: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
advertising: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control或
[root@localhost root]# mii-tool -w
21:20:33 eth0: negotiated 100baseTx-FD, link ok
21:20:33 eth2: no link
//mii-tool 主要是用于配置網(wǎng)卡工作模式的指令，同時也可以進(jìn)行查詢、監(jiān)控等工作！2)
[root@localhost /]# /etc/init.d/network status

[root@localhost root]# service --status-all

[root@localhost /]# ifconfig -a

#ethtool eth2
