项目描述：
熟悉交换机上VLAN的创建及相关配置，给公司各部门划分相应的VLAN进行广播风暴的隔离控制并进行相关测试。
项目实施拓扑图：
项目实施基本要求：
（1）正确选择设备并使用线缆连接；
（2）正确给各个PC配置相关IP地址及子网掩码等参数；
（3）在SW1上配置相关VLAN，并把交换机相应的端口添加到VLAN中。用相关显示命令查看配置结果。
（4）在SW2上配置相关VLAN，并把交换机相应的端口添加到VLAN中。用相关显示命令查看配置结果。
（5）在SW3上配置相关VLAN，并把交换机相应的端口添加到VLAN中。用相关显示命令查看配置结果。
（6）在SW4上进行相关配置，使得不同交换机上的相同部门PC（如销售部PC1和销售部PC3）可以相互访问。
项目拓展要求（选做）：
如何配置下面网络拓扑图中的两个交换机，使得两个不同VLAN中的PC能相互访问。
