5. Spanning Tree特性：包括portfast、Bpduguard、BPDUfilter、Uplinkfast、BackboneFast和RootGuard。例如，portfast特性可以加速端口启动过程，而Bpduguard特性则可以防止BPDU包被发送，以避免环路。6. 相关命令：如Switch(config)#errdisable recovery ?用于查看和修改errdisable的时间间隔，以及Switch#show errdisa...
Use thespanning-tree guard rootInterface (Ethernet, Port Channel) Configuration mode command to enable Root Guard on all spanning-tree instances on the interface. Root guard prevents the interface from becoming the root port of the device. Use thenoform of this command to disable the ro...

An MST region contains two types of spanning tree instances: an Internal Spanning Tree Instance (IST) and Multiple Spanning Tree Instances (MSTI). IST is the default spanning tree instance in MST regions; and is always zero. It gives a root switch to the region that contains all VLANs ...

The MST instance is a spanning tree running in the MST region. Multiple MST instances can be established in one MST region and they are independent of each other. As is shown in Figure 1-4, there are three instances in a region, and each instance has its own root bridge. ...
