基于交换机实现的VLAN技术研究

Research on VLAN technology based on switch

文章旨在探讨基于交换机实现的虚拟局域网(Virtual Local Area Network,VLAN),讨论VLAN的概念及其实现原理、不同VLAN之间的通信技术、VLAN的配置技术、VLAN的优点和缺点等方面。通过文献研究和调查企业网络管理需求,文章确定使用基于交换机实现的VLAN技术的合理性。文章选用适当的交换机设备,利用该设备的特点和功能,建立VLAN网络,并在此基础上进行网络管理,测试各项功能并收集实验数据,进行充分分析与比较。经过实验,发现基于交换机实现的VLAN技术能够实现对网络的分段管理,具有较高的安全性和管理性。同时,实验数据也证明该技术的可行性和有效性。

This study aims to explore the Virtual Local Area Network(VLAN)technology based on switch,discusses the concept of VLAN and its implementation principle,communication between different VLAN,VLAN configuration,VLAN advantages and disadvantages.Through literature research and investigation of enterprise network management requirements,the rationality of using VLAN technology based on switch is determined.Then,the appropriate switch equipment is selected,and the VLAN network is established by using the characteristics and functions of the equipment.On this basis,network management is carried out,various functions are tested,and experimental data are collected for full analysis and comparison.Through experiments,it is found that VLAN technology based on switch can realize the segmentation management of network,and has high security and management.At the same time,the experimental data also prove the feasibility and effectiveness of the technology.
