1、1实验：VLAN 隔离及 VLAN 间通信一、 VLAN/802.1Q本交换机隔离一、实验目的1.理解并掌握 VLAN 的作用及特点。2.熟悉交换机的基本配置，学会在交换机上划分 VLAN 及如何将接口划分到指定的VLAN 中，学会给两台交换机互连的端口配置 TRUNK 模式。3.学会利用 VLAN 的虚拟接口，使处于不同 VLAN 间的计算机也可以进行通讯。二、实验内容及步骤1.实验用到的拓扑图2.实验过程清空交换机原有 VLAN 配置，新建两个 VLAN 10、VLAN 20 并将 f0/5 口加入 VLAN 10,将 f0/15 口加入 VLAN 20。3.交换机配置命令SW1#show
