斯科交换机端口的相关配置.docx

1、斯科交换机端口的相关配置实验三一 实验拓扑图二 实验要求1、 在2950A交换机上创建VTP域名：cisco，设置为server模式，将其它交换机设置为：client模式，将2950A与2950D的F0/3端口、F0/4端口配置为以太通道。2、 在2950A交换机上创立VLAN100、VLAN200，并将F0/2端口划分给VLAN100，F0/1端口划分给VLAN200。3、 在2950B交换机上将F0/1端口、F0/2端口划分给VLAN200。4、 在2950C交换机上将F0/1端口、F0/2端口划分给VLAN100。5、 将2950A设置为VLAN100的根网桥后，查看STP各端口状态的情

2、况。6、 将2950D设置为VLAN200的根网桥后，查看STP各端口状态的情况。7、 通过修改端口成本或端口做优先级，将阻塞端口变为转发状态。8、 假设交换机2950C、2950D的F0/13端口和F0/14端口连接WEB、DNS服务器，请将这些端口配置为速端口。9、 将有阻塞端口的交换机中置为上行链路，提高故障修复率。10、清除交换机所有配置。11、 将拓扑改为最佳方案。三网络接口4950A Fa0/1 4950B Fa0/1 4950A Fa0/2 4950C Fa0/2 4950A Fa0/3 4950D Fa0/3 4950A Fa0/4 4950D Fa0/4 4950B Fa0/
