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.
