1、STP技术实验目的:熟悉掌握STP配置,掌握STP原理及选举过程设备说明:使用小凡模拟器3640实验拓扑:实验步骤:基础配置:(1)把所有线路down掉sw1(config)#intf0/1//把SW1的f0/1端口downsw1(config-if)#shutdownsw1(config)#intf0/2//把SW1的f02端口downsw1(config-if)#shutdownsw2(config)#intf0/1//把SW2的f0/1端口downsw2(config-if)#shutdown(2)

2、在sw1,sw2,sw3都分别创建vlan10,vlan20sw1#vlandatabase//在sw1分别创建vlan10vlan20sw1(vlan)#vlan10sw1(vlan)#vlan20Sw2#vlandatabase//在sw2分别创建vlan10vlan20sw2(vlan)#vlan10sw2(vlan)#vlan20Sw3#vlandatabase//在sw3分别创建vlan10vlan20Sw3(vlan)#vlan10Sw3(vlan)#vlan20(3)把sw1,sw2,sw3

3、的f0/1,f0/2接口划入vlan10sw1(config)#intf0/1sw1(config-if)#switchportaccessvlan10//把f0/1划属于vlan10sw1(config-if)#intf0/2sw1(config-if)#switchportaccessvlan10//把f0/2划属于vlan10sw2(config)#intf0/1sw2(config-if)#switchportaccessvlan10//把f0/1划属于vlan10sw2(config-if)#i

4、ntf0/2sw2(config-if)#switchportaccessvlan10//把f0/2划属于vlan10sw3(config)#intf0/1sw3(config-if)#switchportaccessvlan10//把f0/1划属于vlan10sw3(config-if)#intf0/2sw3(config-if)#switchportaccessvlan10//把f0/2划属于vlan10(3)查看配置信息Sw1sw1#showrunning-configBuildingconfigu
