实验一 交换机的基本操作

1、实验一 交换机的基本操作1.实验目的（1） 熟悉交换机CLI 的各种模式（2） 熟悉交换机CLI 各种编辑命令（3） 掌握交换机的IOS 基本命令：使能密码、以太接口配置（4） 查看交换机的有关信息（5） 熟悉TFTP 服务器的使用（6） 熟悉备份交换机的配置文件（7） 掌握备份交换机的IOS（8） 熟悉交换机的远程登录2.实验设备 交换机一台，电脑一台，网线若干。3.实验拓扑结构图1.14.实验过程4.1超级终端与交换机互联设置4.1.1点击系统的开始程序附件通讯超级终端，进行超级终端连接，如图1.2所示。图 图 弹出连接说明对话框时，为新建的连接输入名称并为

2、该连接选择图标。如图1.4所示。图根据配置线所连接的串行口，选择连接串行口为COM1（依实际情况选择PC机所使用的串口）。如图1.5所示。图设置所选串行口的端口属性端口属性的设置主要包括以下内容：波特率“9600”，数据位“8”，奇偶校验“无”，停止位“1”，数据流控制“无”，如图1.6所示。图检查前面设定的各项参数正确无误后，交换机就可以加电启动，进行系统的初始化，进入配置模式进行操作。可以看到如下界面：Welcome !.4.2交换机的基本操作4.2.1 模式切换Switch>Switch>enSwitch#config tEnt
