Usage Guideline
Use this command to display the MSTP configuration and operation status. If a private VLAN is
configured and the secondary VLAN does not map to the same primary VLAN, the show spanning-tree
mst configuration command will display a message to indicate this condition.
Example
This example shows how to display MSTP detailed information.
