一、通过mii-tool指令
[root@linuxzgf ~]# mii-tool
//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！
二、ethtool
[root@linuxzgf ~]# ethtool eth0
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 0
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: umbg
Wake-on: g
Current message level: 0x00000007 (7)
Link detected: yes
从上面 Link detected 可以看出eth0 处于连接状态
三.[root@linuxzgf ~]# /etc/init.d/network status
配置设备：
lo eth0 eth0.10 eth0.2 eth0.3 eth0.4 eth0.5 eth0.7 eth0.8 eth1
当前的活跃设备：
lo eth0 eth0.10
[四、ifconfig -a
[root@linuxzgf ~]# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:E0:81:80:D8:96

五、lspci也可以看到网卡的信息
