六、 实验步骤
路由器A 的基本配置：
第一步：恢复出厂设置
Router>enable ！进入特权模式
Router#2004-1-1 00:32:10 User DEFAULT enter privilege mode from console 0, level = 15
Router#show running-config ！查看当前配置
Building configuration...
Current configuration:
!
!version 1.3.2E
<省略>
Router#delete ！删除配置文件
this file will be erased,are you sure?(y/n)y
Router#reboot ！重新启动
Do you want to reboot the router(y/n)?y
Please wait…..
第二步：设置接口IP 地址、DCE 的时钟频率以及验证
Router>enable ！进入特权模式
Router #config ！进入全局配置模式
Router _config#hostname Router-A ！修改机器名
Router-A_config#interface s1/1 ！进入接口模式
Router-A_config_s1/0#ip address 192.168.1.1 255.255.255.0 ！配置IP 地址
Router-A_config_s1/0#physical-layer speed 64000 ！配置DCE 时钟频率
Router-A_config_s1/0#no shutdown
Router-A_config_s1/0#^Z ！按ctrl + z 进入特权模式
Router-A#show interface s1/1 ！查看接口状态

第三步：设置特权模式密码
Router-A_config#enable password 0 digitalchina ！0 表示明文
Router-A_config#^Z
Router-A#2004-1-1 16:38:49 Configured from console 0 by DEFAULT
Router-A#exit
Router-A>enable ！再次进入特权模式
Password: ！需要输入密码
Access deny !
Router-A>enable
Password: ！注意输入时不显示
Router-A#2004-1-1 16:39:14 User DEFAULT enter privilege mode from console 0, level = 15
