2、/22 F0/21 Cisco 3560 Cisco 3560 测试在网络环境中 CISCO与H3C设备之间的生成树运行兼容性 CISCO : 3550 一台、3560 一台 H3C : 3600 两台 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 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。

3、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） H3C MSTP 与CISCO MST 对接成功 H3C与CISCO STP对接只能同时运行 MST才可以 实验拓扑一： H3C 3600-1 配置： stp in sta nee 1 priority 4096 stp in sta nee 2 priority 8192 stp en able stp regi on-con figurati on regi on-n ame S revisi on-level 1 in sta nce 1 vla n 110 120 in sta nce
