摘要
简要阐述了VLAN技术在网络中的重要性,在网络配置过程中对于tagged与untagged两个参数的选择存在的疑问;深入讲解tag的定义,同时结合实例,全面分析了VLAN的端口在untagged与tagged两种状态下,数据帧在通信过程中是否出现tag header的标识;总结出规律,有助于在VLAN中如何准确地使用tagged与untagged.
Briefly presenting the importance of VLAN in the network, and the questions about the choice of the two parameters between tagged and untagged when configuring VLAN; proceeding from the definition of tag, through the explaining of the example, this paper fully analyzes whether the tag header appears in the frame in the communication process of VLAN when the port is at the two states of untagged and tagged, and finally reach a conclusion to help to make use of tagged and untagged correctly in VLAN.
