[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

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)
[root@localhost /]# /etc/init.d/network status
Configured devices:
lo eth0 eth1
Currently active devices:
lo eth0
等同于
[root@localhost root]# service --status-all
............

3)ifconfig -a
[root@localhost /]# ifconfig -a
