%SYS-5-CONFIG_I: Configured from console by console
 

2）全局模式下路由器命名为Router2811：

Router>en
Router#config t
Router(config)#hostname Router2811
Router2811(config)#

3）全局模式下更改系统时间(需要到真机上实验)：

Router2811(config)#clock set 15:41:52 March 06 2012            //设置时间
Router2811#show clock             //查看时间

4）路由器设置登录信息：welcome to Router2811。

Router2811(config)#banner motd #welcome to Router2811#       //注意motd与#之间有空格
Router2811(config)#end            // 一次退出到特权模式
Router2811#
%SYS-5-CONFIG_I: Configured from console by console

Router2811#exit         //退出终端窗口后再次进入到用户模式即可看到登录消息

Router2811 con0 is now available

Press RETURN to get started.

welcome to Router2811

Router2811>

5）接口描述配置，给serial 0/0/1接口配置描述信息：Link to serial 0/0/1 of Router2811

Router2811(config)#interface serial 0/0/1
Router2811(config-if)#description Link to serial 0/0/1 of Router2811
Router2811(config-if)#end    
Router2811#
%SYS-5-CONFIG_I: Configured from console by console

Router2811#
Router2811#show run          //在特权模式查看配置信息如接口，以下红色字体

6）console线路端口（通过配置线+超级终端连接路由器，物理连接）密码配置：

Router2811#config t       //进入全局模式
Enter configuration commands, one per line.  End with CNTL/Z.
Router2811(config)#line con 0         //进入到console线路配置模式
Router2811(config-line)#password 123456    //设置密码
Router2811(config-line)#login        //登录时必须输入口令
Router2811(config-line)#end        
Router2811#
%SYS-5-CONFIG_I: Configured from console by console

Router2811#write     //保存配置
Building configuration...
[OK]
Router2811#exit       //退出终端窗口

Router2811 con0 is now available

Press RETURN to get started.

welcome to Router2811

User Access Verification

Password: 123456                     //再次进入需要输入上面设置的密码

另外:console端口也可设置本地数据库密码：

Router2811(config)#username admin secret 123456       //添加本地数据库用户和密码
Router2811(config)#line con 0          //进入到console
Router2811(config-line)#login local                //使用路由器本地配置的用户和口令登录
Router2811(config-line)#end
 

7）VTY虚拟终端（通过网络连接路由器进行管理如telnet和ssh连接）

Router2811#
Router2811#config t
Enter configuration commands, one per line.  End with CNTL/Z.
Router2811(config)#line vty 0 4
Router2811(config-line)#password 123456
Router2811(config-line)#login
Router2811(config-line)#

8）特权密码设置

密文密码加密

Router2811#config t
Enter configuration commands, one per line.  End with CNTL/Z.
Router2811(config)#enable secret 123456       //特权密文密码
Router2811(config)#end
Router2811#
 

明文密码加密

Router2811#config t
Enter configuration commands, one per line.  End with CNTL/Z.
Router2811(config)#enable password 123456   //明文密码，两者同时设置明文密码失效
Router2811(config)#service password-encryption     //明文密码加密
Router2811(config)#end
Router2811#
 

9)路由器管理接口IP设置

Router2811#config t
Enter configuration commands, one per line.  End with CNTL/Z.
Router2811(config)#int vlan1
Router2811(config-if)#ip add 255.255.255.0       //配置接口IP
Router2811(config-if)#no shutdown    //激活端口
Router2811(config-if)#end
Router2811#

10）查看路由相关信息

Router2811#show run                     //查看在RAM中当前配置

Router2811#show start                   //查看在NVRAM中已保存的配置

Router2811#show version               //查看路由器基本信息如型号、版本、IOS信息等

11）查看接口相关信息
