實驗三網(wǎng)絡模擬軟件的使用(下)

1、實驗三網(wǎng)絡模擬軟件的使用（下）-交換機VLAN實驗1.規(guī)劃ip地址PCA的ip地址：PCB的ip地址：*rpcc擊鍵總數(shù)fl：5鍵值RedHatLinuxrelease7.3(Valhalla)PCClogin!rootPassword：IirukrootPCCroot#IfconfigcthQ10.65.1.3*IroQtPCCroot#ifconfigloopbackinetaddr：1：rootPCCroot#PCD勺ip地址：SWA的ip地址：SWB的ip地址：的f0/5f0/7vlan2,f0/8為trunkSWB的f0/5f0/7valn2,f0/1為trunk用ping命令測試，

2、從PCA和PCB到各點的連通情況。由于交換機初始化為vlan1,因為同網(wǎng)段的可以通。即PCA到PCCSWASWB是通的，而PCB只與PCD。2.設置VLAN雙擊SwitchA，改名SwitchA為SWA建立2個vian，分別為vlan2、vlan3switchenswitch#shvianswitch#conftswitch(config)#hosthameSWAswitch(config)#exitSWA#viandatabaseSWA(vian)#vian2SWA(vian)#vian3SWA(vian)#exitSWA#conftSWA#shvian至此在SWA上建立了兩個vian,sh
