用vlan,trunk,级联实现网络连接实例

实验前奏，本实验需一台三层交换机，两台二层交换机，两台PC,若干条交叉线和直通线。如下拓扑图356Multilay□0l24PS买干Switchl]-24295Swlfch3Switch^'.IPC-PTPGRaPC-PTPC4 1，在三层交换机中进入356Multilay□0l24PS买干Switchl]-24295Swlfch3Switch^'.IPC-PTPGRaPC-PTPC4 1，在三层交换机中进入vlan模式下，配置vtp和新建服务模式server2，三层交换机中新建vlanSuitch(vlEQi：IifvlELti100VLAIJ100added:NaiLLe:VLAIJOIOOSuitch(vlEQi：IitvlELtiZ00VLAIJZOOadded:NaiLLe:VLAI-IOZOOSuitch(vlEQi)#3，配置vlan的ipSuitch(config)ftintvlai±100statetoup%LIM1：-S-CHAI-IGED:InterfaceVlaiilOO,changedSwitchi：config-if)flipaddress192.168■丄.2542SS.£££.£££.DSwitch(config-if)Sintvlaii£00Switch(config-if)ft%LINIC-S-CHAIJGED:Int.erfaceVlaiiZ00*cliaiigedstatetoupSwitch(config-if)tripaddress19Z-168-Z-ZE4ZSS.ZSS.255.04,三层交换机的F0/1端口中配置trunkSwitchi：config-if)Sintf0/1Switch(config-if)#suitclipurtillodetrmikCoiiiiLLELtidreject-ed:Ailinterfacewhosetrmiknfiiip-iredto"t-ri-uik11elode-Switch(config-if)#suitcliporttri_uikal1owedencapsulationis"Auto"caiinotbecovlaiiall改两台二层交换机的名字switch1,switch2Switchi：config)ftliost-naiiiesuitchiswitchi(config)ttSwitch(config)tthostnaiLLeswitchZswitch£(config)ft分别为二层交换机建vlanSuitch(vlail)itvlail100VTPVLAIJconfiiT-irationnotall口mec!whendeviceisinCLIENTiiiodesuitchZ(vlail)itvlail200VLAIJZOOadded:Naiiie:VLAIJ0200分别为二层交换机配置vtpclient模式Suitchifvlaildatatiase%Uarning:Itisrecoiiiiiiendedtoconfiizn.ireVLANfroiiiconfigmode,asVLANdatat<asemodeisbeingdeprecated.PleaseconsultuserdoCLiiiientationforconfiigi-iringVTP/VLAI-Jinconfigiiiode.Suitch(vlail)#vtpdoniaiiiminChangingVTPdijiiiainnaiiiefroiiiMULLtoiiiinSuitch(vlan)#vtpclientSettingdevicet■口VTPCLIENTmude.switchZ(vlai±) doiiiainiiiinChaiigingVTPdoiiiainnaiiiefroiiiNULLtoiiiinswitchZ(vlail) clientSett-ingdevice七口VTPCLIENTm口de_switchZ(vlaii)ft&为switchl的端口f0/l,f0/2,switch2的端口fO/1配置trunksuitchi(configjSintf0/1suitchi(config-if)itswitcliportiiiodettrunk%LINEPP.OTO-5-UPDOW:LineprotocolonInterfaceFast-Ethernet-0/1odoT.ni%LINEPP.OTO-5-UPDLiW:Linepro七□c□丄onInterfaceFast-EthernetO/1oupsuitchi(config-if)itswitchport七trunkallowedvlaiiallsuitchi(config-if)itintf0/Eswitchl(config-if)#switcliportmodetrmik%LINEPP.OTO-5-UPD0W:LineprotocolonInterfaceFast-Ethernet-0/ZodoT.rtisuitchi(config-if)it%LINEPP.OTO-5-UPD0W:LineprotocolonInterfaceFastEthernet-0/Zoupchaiigedstatetchangedstatetcliaiigedstatet-chaiigedstatet-iLLddetri-uikiLLddetri-uik■trunkallowedvlaiiallsuitchZ(ccmfig)itintf0/1Ewitch2(config-if)#switcliportswitchZ(config-if)ftsuitcliport
