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...

spanning-tree [mst <instance-id>] priority <value(0-61440)> no spanning-tree [mst <instance-id(1-64)>] priority Parameter Description mst <instance-id>- Configures the ID of MSTP instance already created in the Switch. This value ranges between 1 and 64. The special ...
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. ...
