Usage Guide: Whether the switch is in the MSTP region mode or not, users can enter
the MSTP mode, configure the attributes, and save the configuration. When the switch
is running in the MSTP mode, the system will generate the MST configuration identifier
according to the MSTP configuration. Only if the switches with the same MST
configuration identifier are considered as in the same MSTP region.
Example: Enter MSTP region mode.
Switch(config)#spanning-tree mst configuration
Switch(Config-Mstp-Region)#
