《计算机网络》实验

实验名称：交换机的配置及VLAN的划分

实验目的：熟悉交换机的CLL加深理解VLAN、Trunk、Spanning Tree等一些相关的概念。

　实验内容：对交换机进行一些基本的配置，学习对交换机各端口进行基本的参数设置，同时 学习VLAN的划分和用ISL协议配蟹F线。

实验设备：两台Cisco Catalyst 1900交换机、一台Cisco 2621路由器和四台PC。

实验步骤：

1、按实验原理图连接设备，为四台主机设程IP地址：

6、 练习 “ctrl+A”、“ctrl+E”、“ctrl+B”、“ctri+P” 等组合键的使用：

7、 学习如何进行“端口配置模式”、"全局配置”、“特权模式”和“用户模式”之间的 转换，学习不同状态下帮助的获得：

8、 练习进行各种命令的配置和解除，包括:**console password'\ “telnet password"、uauxiliary passwod"、**enable password"secret password” 等；

1、 router(config)tenable password cisco

命令解释：开启特权密码保护。

2^ router(config)tenable secret class

命令解释：开启特权密匙保护。

这两个密码是用来限制非授权用户进入特权模式。因为特权密码是未加密的，一般都推荐 用户使用特权密匙，且特权密码仅在特权密匙未使用的情况下才会有效。

配置控制端口的用户密码

1、 router(config)#lin亡 console 0

命令解释：进入控制线路配置模式。

2、 router(config-line)#1ogin

命令解释：开启登陆密码保护

3^ router(config-line)#password cisco

命令解释:设置密码为Cisco,这里的密码区分大小写。

　配置辅助端口(AUX)的用户密码：

1、 router(config)#1ine aux 0

命令解释:进入辅助端口配宜模式。

2、 router(config-1ine)#1ogin

命令解释：开启登陆密码保护

3、router(config-1ine)^password cisco

命令解释:设置密码为Cisco,这里的密码区分大小写。

配置VTY(telnet)登陆访问密码：

1、 router(config)#1ine vty 0 4

命令解释:进入VTY配置模式。

2、 router(config-line)#1ogin

命令解释：开启登陆密码保护
