《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：

实验要求：按照上述实验步骤进行正确的配置后，位于不R vlan的汁算机应该可以相互进行通讯（用“ping”命令检测）。

实验原理图:

《计算机网络》实验二

实验名称：路由器及路由协议的配置

实验目的：1、进一步理解路由器的主要组成部分及其功能，初步掌握IOS的一些基本命令, 学习对路由器进行安全设宜和基本的日常维护。

2、理解利用路由器IP包进行路由的基本原理及方法，初步掌握柑关的一些IOS命令, 学习对路由器的路由表进行查看。

实验内容：1、学习检査路由器的主要参数和进行一些基本的设巻：

2、学会对路由器进行各种口令的设置；

3、掌握路由器一些关键文件的备份。

4、静态路由的配置：

5、 R I P协议的配置：

6、 I G RP协议的配置

实验设备：三台Cisco 25XX路由器和一台PC.

实验步骤：

一、路由器的基本配置

1、将路由骼与终端相连，加电启动路由器，进入命令行配置方式;

2、在“用户模式”下输入“Enable"进入“特权模式”,在“特权模式”下输入“conf L进入“全局配置”模式：

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
