實驗步驟：

　　1、修改網卡名的配置文件；

　　2、卸載網卡驅動；

　　3、裝載網卡驅動。

#1、修改網卡名的配置文件
#修改網卡名的配置文件，在/etc/udev/rules.d/70-persistent-net.rules
[root@localhost6 ~]#cd /etc/udev/
[root@localhost6 udev]#ls
makedev.d rules.d udev.conf
[root@localhost6 udev]#cd rules.d/ [root@localhost6 rules.d]#ls 60-fprint-autosuspend.rules 60-raw.rules 90-alsa.rules 99-fuse.rules 60-openct.rules 70-persistent-cd.rules 90-hal.rules 60-pcmcia.rules 70-persistent-net.rules 98-kexec.rules [root@localhost6 rules.d]#vi 70-persistent-net.rules # This file was automatically generated by the /lib/udev/write_net_rules # program, run by the persistent-net-generator.rules rules file. # # You can modify it, as long as you keep each rule on a single # line, and change only the value of the NAME= key.# PCI device 0x8086:0x100f (e1000) ##e1000驅動程序名 SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:d7:91:33", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"# PCI device 0x8086:0x100f (e1000) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:d7:91:3d", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" ~ ##將NAME="eth1"修改成ethxin ~ ~ ~ "70-persistent-net.rules" 11L, 585C

[root@localhost6 rules.d]#lsmod | grep -i 'e1000'　　#查看驅動程序模塊
e1000 134863 0

#2、卸載網卡驅動
[root@localhost6 rules.d]#modprobe -r e1000　　#卸載網卡驅動
[root@localhost6 rules.d]#lsmod | grep -i 'e1000'　　#查看驅動程序模塊，沒有數據顯示 #3、裝載網卡驅動
[root@localhost6 ~]#modprobe e1000　　#裝載網卡
[root@localhost6 ~]#ip a
