1、通过二层交换机实现VLAN划分实验名称通过二层交换机实现VLAN内部通信。实验目的掌握如何通过二层交换机实现VLAN内部通信。实现功能使在同一 VLAN里的计算机系统能跨交换机进行相互通信，而在不同VLAN里的计算机系统不 能相互通信。实验拓扑1实验布局v1：=ltl 2v1：=ltl 3v1：=ltl 2v1：=ltl 32配置信息1) SwitchO配置信息SwitchenSwitch#config tEnd with CNTL/Z.Enter configuration commands, one per line.Switch(config)#interface fa0/1Switch
