Implementing the Multiple Spanning Tree Protocol – MSTP
How to configure and verify MST

Use the show spanning-tree mst command to display MST information.

Example: Displaying MST Configuration Information
This example shows how to display MST configuration information. This includes MST region name, revision number and VLAN to MST instances (MSTI) mapping:

Example: Displaying General MST Information
This example shows how to display general MST information. Notice that the output is grouped by MSTIs starting with the Internal Spanning-Tree (IST):

Example: Displaying MST Information for a Specific Instance

Switch#show spanning-tree mst 1

Example: Displaying MST Information for a Specific Interface
This example displays MST information for a specific interface:

Switch#show spanning-tree mst interface fastethernet 4/4

Example: Displaying MST Information for a Specific Instance and Interface
This example displays MST information for a specific interface and a specific MSTI:

Switch#show spanning-tree mst 1 interface fastethernet 4/4

Example: Displaying Detailed MST Information
This example displays detailed MST information for a specific instance:

Switch#show spanning-tree mst 1 detail
