本实验是对Cisco Catalyst 1900系列交换机的启动和基本设置的操作。
1.实验目的
通过本实验，读者可以掌握以下技能
熟悉交换机的开机界面;
对交换机进行基本的设置;
理解交换机的端口及其编号。
2.设备需求
本实验需要以下设备:
Cisco Catalyst 1900系列交换机1台，型号不限，企业版软件，本实验中使用了1912交换机;
PC机1台，操作系统为Windows系列。装有超级终端程序;
Console电缆1条及相应的接口转换器。
3.线缆连接及配置说明
如图3.1所示，PC机通过串口与交换机的Console端口相连。
 |
和路由器一样，Cisco交换机的Console端口的缺省设置如下
端口速率:9600bit/s
数据位:8
奇偶校验:无
停止位:1
流控:无
把PC机超级终端程序中串行端口的属性设置成与上述参数一致后，便可以开始实验。
4.实验配置及监测结果
在PC机启动正常，PC机与交换机使用Console电缆连接起来，并且已经进入超级终端程序的情况下。接通交
换机电源。
由于交换机没有电源开关，接通电源即直接插上电源插头。
监测清单3.1记录了Catalyst 1912交换机启动的全过程。
