摘要
VLAN原理实验利用协议分析方法,测试验证VLAN实现的功能,以及交换机不同属性端口接收、转发普通帧和标记帧的特性,观察支持VLAN的交换机对以太帧插入、删除802.1Q标记的过程。并通过错误配置交换机端口属性,演示交换机加、去标记失配导致的网络故障,以加深学生对IEEE 802.1Q VLAN原理的理解。
VLAN is one important networking technology.An IEEE 802.1Q VLAN principle experiment designed is based on protocol analysis.The experimental test verifies the functions of VLAN,as well as the regulation of different attribute ports of switches of receiving and transmitting common frames and tagged frames.From the experiment,students can observe when and how support VLAN Ethernet switches add or remove 802.1Q tag to or from frames.Furthermore,students can experience network trouble due to switches add or remove tag to or from frames by inaccurate configuring switch ports attributes.The experiment can facilitate students better understanding frame structures and switching principles of IEEE802.1Q VLAN.
