基本实验

路由器基本操作

1.

Router> //用户模式

Router>enable //在用户模式敲入enable 进入特权模式(也叫enable 模式)

Router#disable //在特权模式敲入disable 退出到用户模式

Router>enable //在用户模式敲入enable 进入特权模式

Router#configure terminal //在特权模式敲入configure terminal 进入到配置模式

Router(config)#interface ethernet 0/0 //在配置模式敲入“interface+接口类型+接口编号”进入接口模式

Router(config-if)#exit //敲入exit 退出接口模式

Router(config)#router rip //敲入“router + 路由协议”进入router 模式

Router(config-router)#exit //退出router 模式

Router(config)#line console 0 //进入line 模式

Router(config-line)#end //从line 模式退出(任何时候敲入end 会退出到特权模式)

Router#conf t

Router(config)#interface ethernet 0/0.1 //进入子接口模式

Router(config-subif)#end //任何时候敲入end 会退出到特权模式

常用show命令的介绍:

Router#show version 查看路由器版本

Router#show flash: 查看路由器flash

Router#show history 查看历史命令记录

Router#show interfaces s0/0 查看接口物理相关信息

Router#show ip int s0/0 查看接口协议相关信息

Router#show ip int brief 查看接口简要信息

Router#show running-config 查看路由器启动配置文件

Router#show running-config 查看路由器运行配置文件

Router#show users 查看当前登录的所有用户

Router#show arp 查看路由器ARP表

试验如下图:
