CISCO 与 H3C STP对接测试 实验时间 2015/10/23 实验人 范四周

实验名称 CISCO 与 H3C STP 对接 实验目的 测试在网络环境中CISCO与H3C设备之间的生成树运行兼容性

实验设备 CISCO:3550一台、3560一台 H3C : 3600两台

实验配置注意事项 1、 H3C 全局必须配置 stp config-digest-snooping 2、 H3C 与 CISCO 互连接口下必须配置 stp config-digest-snooping 3、 在 MST 域内 所有设备region-name和 revision-level一致 4、 CISCO设备默认NATIVE VLAN 1,在此实验中不能更改掉NATIVE VLAN 1,否则无法对接。 5、 H3C 设备默认PVID 1,是否更改对设备无影响(H3C 始终默认VLAN 1 通过UNTAG) 实验结果分析 H3C MSTP 与CISCO MST 对接成功

实验结论 H3C与CISCO STP 对接只能同时运行MST才可以 实验拓扑一:
