4. 路由器的基本配置
Router#config terminal
Router(config)#hostname cipon
cipon (config)#
cipon(config)#banner motd # welcome to cipon #
cipon(config)#interface ethernet 0
cipon(config-if)#description Link to RD Department
cipon(config-if)#exit
cipon(config)#exit
cipon#
cipon(config-if)#end
cipon#exit
cipon con0 is now available
Press RETURN to get started.
↙↙
welcome to cipon
cipon>
cipon>
cipon>enable
cipon#sh int eth0
Ethernet0 is administratively down , line protocol is down
Hardware is DEC21140, address is ca00.17ac.0000 (bia ca00.17ac.0000)
Description: Link to RD Department
MTU 1500 bytes , BW 10000 Kbit/sec , DLY 100 usec,

5.可以给路由器的特权模式配置登录密码，当操作员要从用户模式进入到特权模式时则必须输入我们设定的密码。
Cisco提供了两种密码模型：普通密码与MD5加密密码.
6. 配置命令别名(Aliases)，以较简洁的命令来代替一个真实的命令
7. 备份和恢复Router的配置文件
8. 清除启动文件
9. 基本管理安全配置
