实验成绩
一、实验目的
1、了解交换机的作用。

2、掌握交换机的基本配置方法。

3、熟悉Packet Tracer 5.3 交换机模拟软件的使用。

二、实验仪器设备及软件
以太网交换机一台、一台PC、专用配置电缆一根、网线一根。

三、实验步骤
1、在任何模式下，用户在输入命令时，不用全部将其输入，只要前几个字母能够唯一标识该命令便可，在此时按Tab键将显示全称。

2、在任何模式下，输入一个“？”即可显示所有在该模式下的命令。

3、如果不会拼写某个命令，可以键入开始的几个字母，在其后紧跟一个“？”，交换机即显示有什么样的命令与其匹配。

4、如不知道命令后面的参数应是什么，可以在该命令的关键字后加一个空格，键入“？”，交换机即会提示与“？”对应的参数是什么，例如，Switch#show？
5、要删除某条配置命令，在原配置命令前加一个no和空格。

6、了解交换机各种配置模式的功能。

7、修改交换机名称和密码。

退到上一层模式用“exit”，要退到特权模式用“end”。

查看交换机配置文件信息用show startup-config，查看当前所有配置信息用show running-config。

重启交换机用reload命令。

8、将IP地址和telnet配置好。

9、连接登录到真正cisco设备的过程，有以下四种方式：
a、通过Console终端方式；
b、通过telnet远程访问；
c、通过Web管理界面；
d、通过网管软件。

步骤1：要连接一台还没配置的新交换机或者没有管理IP地址的交换机，只能用终端方式访问，利用console线连接设备的console口与PC机的串口。

步骤2：设置好交换机的管理IP地址后，就可以通过telnet登录到交换机，进行管理。

步骤3：PC机telnet到该地址上访问。

五、实验总结及体会
命令行操作进行自动补齐或命令简写时，要求所简写的字母必须能够惟一区别该命令。

如switch# conf可以代表configure，但switch#co无法代表configure，因为co开头的命令有两个copy和configure，设备无法区别。

注意区别每个操作模式下可执行的命令种类。

交换机不可以跨模式执行命令。
