XXX学院利用VLAN技术为企业开创网络管理新时代利用VLAN技术为企业开创网络管理新时代摘要VLAN(虚拟局域网)是一个在物理网络上根据用途，工作组、应用等来逻辑划分的局域网络，是一个广播域，是目前应用比较广泛的一种网络管理手段。在早期的采用交换技术的网络模式中，对于网络结构的划分采用的仅仅是物理网段的划分的手段。这样的网络结构从效率和安全性的角度来考虑都是有所欠缺的，而目前企业网络管理中VLAN的应用已经比较广泛了，利用VLAN技术，可以为企业降低网络管理成本和提升网络运行和管理效率。由于VLAN中的网络用户是通过LAN交换机来通信的，所以对于企业各部门之间的信息安全也有很大的保证。本文主要探讨的是VLAN(虚拟局域网)技术在企业网络管理和应用。关键词:VLAN，网络管理，应用VLAN(VirtualLAN)isaphysicalnetworkonthebasisofuse,theworkinggroup,applicationtothelogicaldivisionoflocalareanetwork,abroadcastdomain,isusedwidelyinanetworkmanagementtool.Intheearlyadoptionofswitchingtechnologynetworkmodel,networkstructureforthedivisionofthephysicalnetworksegmentisonlyusedbythedivisionmeans.Thisnetworkstructurefromtheefficiencyandsafetypointofviewislacking,andthecurrentmanagementVLANoftheenterprisenetworkapplicationshavebeenmoreextensive,andtheuseofVLANtechnology,networkmanagementforenterprisestoreducecostsandimprovenetworkmanagementefficiency.AstheuserVLANinthenetworkswitchtoHexingmunicatethroughaLAN,sobetweenthevariousdepartmentsforcorporateinformationsecurityisalsoagreatguarantee.ThisarticleexplorestheVLAN(VirtualLAN)technologyintheenterprisenetworkmanagementandapplications.Keywords:VLAN,networkmanagement,applicationIXXX学院利用VLAN技术为企业开创网络管理新时代目录利用VLAN技术为企业开创网络管理新时代...............................................................................I第一章绪论............................................................................................................................1第二章VLAN与企业网络管理的设计与分析.....................................................................32.3拓扑结构分析............................................................................................................32.4设备选型....................................................................................................................4第三章VLAN的具体配置与应用.........................................................................................63.1VLAN的划分原则.....................................................................................................63.2VLAN的划分策略.....................................................................................................63.3VLAN的详细设置.....................................................................................................73.3.1管理部门子网VLAN设置.............................................................................73.3.2其他下属部门子网VLAN设置.....................................................................83.4企业网络ACL设置.................................................................................................11第四章VLAN与企业网络安全...........................................................................................124.1常见的VLAN攻击..................................................................................................124.1.1802.1Q和ISL标记攻击..............................................................................124.1.2双封装802.1Q/嵌套式VLAN攻击....................
