快速生成树配置(cisco),快速生成树配置实验报告

('实验五、快速生成树配置一、实验目的：掌握交换机上生成树协议的诊断方法。二、背景描述：假设某企业采用两台交换机组成一个局网,由于很多数据流量是跨过交换机进行转发的,因此需要提高交换机之间的传输带宽,并实现链路冗余备分,为此网络管理员在两台交换机之间采用两根网线互联,三、实现功能：配置两个交换机之间的冗余主干道，对运行的生成树协议进行诊断。四、实验设备：CISCO交换机Catalyst2950两台，控制台电缆一条，交叉双绞线若干。五、实验拓扑：六、实验步骤：F0/5switchBswitchAPCPCF0/1F0/1F0/2F0/2F0/51、交换机switchA的基本配置:Switch>enableSwitch#configureterminalEnterconfigurationcommands,oneperline.EndwithCNTL/Z.Switch(config)#hostnameSwitchASwitchA(config)#vlan10VLAN10added:Name:VLAN0010SwitchA(config)#interfacevlan10SwitchA(config-if)#ipaddress192.168.0.1255.255.255.0SwitchA(config-if)#exitSwitchA(config)#interfacefa0/5SwitchA(config-if)#switchportaccessvlan10SwitchA(config-if)#exitSwitchA(config)#interfacefa0/1SwitchA(config-if)#switchportmodetrunkSwitchA(config-if)#interfacefa0/2SwitchA(config-if)#switchportmodetrunkSwitchA(config-if)#exitSwitchA(config)#spanning-treeportfastdefaultSwitchA(config)#exitSwitchA#showspanning-treeVLAN001SpanningtreeenabledprotocolieeeRootIDPriority32768Address000C.1000.4605ThisbridgeistherootHelloTime2secMaxAge20secForwardDelay15secBridgeIDPriority32768Address000C.1000.4605HelloTime2secMaxAge20secForwardDelay15secAgingTime300InterfacePortIDDesignatedPortIDNamePrio.NbrCostStsCostBridgeIDPrio.Nbr-------------------------------------------------------------------------Fa0/132768.10FWD032768000C.1000.46050.1Fa0/232768.20FWD032768000C.1000.46050.210SpanningtreeenabledprotocolieeeRootIDPriority32768Address000C.1000.4605ThisbridgeistherootHelloTime2secMaxAge20secForwardDelay15secBridgeIDPriority32768Address000C.1000.4605HelloTime2secMaxAge20secForwardDelay15secAgingTime300InterfacePortIDDesignatedPortIDNamePrio.NbrCostStsCostBridgeIDPrio.Nbr-------------------------------------------------------------------------Fa0/132768.10FWD032768000C.1000.46050.1Fa0/232768.20FWD032768000C.1000.46050.2Fa0/532768.50FWD032768000C.1000.46050.52、交换机switchB的配置：Switch>enableSwitch#configureterminalEnterconfigurationcommands,oneperline.EndwithCNTL/Z.Switch(config)#hostnameSwitchBSwitchB(config)#vlan10VLAN10added:Name:VLAN0010SwitchB(config)#interfacefa0/5SwitchB(config-if)#switchportaccessvlan10SwitchB(config-if)#exitSwitchB(config)#spanning-treeportfastdefaultSwitchB(config)#interfacefa0/1SwitchB(config-if)#switchportmodetrunkSwitchB(config-if)#exitSwitchB(config)#interfacefa0/2SwitchB(config-if)#switchportmodetrunkSwitchB(config-if)#exitSwitchB#showspanning-treeVLAN001SpanningtreeenabledprotocolieeeRootIDPriority32768Address000C.1000.4605HelloTime2secMaxAge20secForwardDelay15secBridgeIDPriority32768Address000C.4006.4286HelloTime2secMaxAge20secForwardDelay15secAgingTime300InterfacePortIDDesignatedPortIDNamePrio.NbrCostStsCostBridgeIDPrio.Nbr-------------------------------------------------------------------------Fa0/132768.119FWD032768000C.1000.460519.1Fa0/232768.219BLK032768000C.1000.460519.2VLAN0010SpanningtreeenabledprotocolieeeRootIDPriority32768Address000C.1000.4605HelloTime2secMaxAge20secForwardDelay15secBridgeIDPriority32768Address000C.4006.4286HelloTime2secMaxAge20secForwardDelay15secAgingTime300InterfacePortIDDesignatedPortIDNamePrio.NbrCostStsCostBridgeIDPrio.Nbr-------------------------------------------------------------------------Fa0/132768.119FWD032768000C.1000.460519.1Fa0/232768.219BLK032768000C.1000.460519.2Fa0/532768.50FWD032768000C.4006.42860.53.如果switchA与switchB间的端口F0/1之间的链路down掉，验证PC1与PC2仍能互相ping通，并观察ping的丢包情况。都通是ping一下没有丢包，共四个包。正ping的同时拔去端口F0/1之间的链路，就丢掉一个包，剩三个包。',)
