Linux下查看网卡信息(转载)
1) 通过mii-tool指令
[root@localhost root]# mii-tool
eth0: negotiated 100baseTx-FD, link ok
eth1: 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
eth1: 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 eth1: no link
//mii-tool主要是用于配置网卡工作模式的指令，同时也可以进行查询、监控等工作！
2)使用工具 ethtool ethx 查看指定网卡的状态
ethtool eth0[code]
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Half 1000baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Half 1000baseT/Full
Advertised auto-negotiation: Yes
Speed: 1000Mb/s

PHYAD: 0
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: g
Wake-on: d
Current message level: 0x00000037 (55)
Link detected: yes[/code]
3)lspci
4)ifconfig
eth0
Link encap:Ethernet HWaddr 00:0C:29:0C:4B:0F
inet addr:192.168.37.128 Bcast:192.168.37.255 Mask:255.255.255.0

他们分别表示：
Eth0：网络接口
link encap:网络类型
HWaddr:网卡物理地址
Inet addr ：IP地址
Bcast：广播地址
Mask：子网掩码
UP：正在使用的网络接口
RX packets,TX packets接收和传输的数据包个数
RX byte，TX byte表示接搜和传输的具体数目
Interrupt：终端信息
Base address：内存地址
网卡配置文件
每一个网络介质都对应一个配置文件，超级用户可以通
