1.实验目的
通过本实验，读者可以掌握以下技能:
配置VLAN;
通过VLAN Trunk配置跨交换机的VLAN;
配置VTP;
配置STP;
查看上述配置项目的相关信息。
2.设备需求
本实验需要以下设备:
Cisco Catalyst 1900系列交换机2台，型号不限，企业版软件，本实验中使用了1912交换机;
交叉线序网线1条;
1台终端服务器，如Cisco 2509路由器，及用于反向Telnet的相应电缆;
1台带有超级终端程序的PC机，以及Consoie电缆及转接器。
3. 线缆连接及配置说明
如下图所示，用交叉网线把 SW1交换机的Fast Ethernet0/26端口和SW2交换机的Fast Ethernet0/26端口连接起来。
图示中略去了作为终端服务器的路由器和作为超级终端的PC机。
4. 实验配置及监测结果
电缆连接完成后。给所有设备加电，开始进行实验。
监测清单记录了本实验的操作。
