You must enable MSTP for the device before any other MSTP-related configuration can take
effect.
To control MSTP flexibly, you can use the undo stp enable command to disable the MSTP feature
for certain ports so that they will not take part in spanning tree calculation and thus to save the
device's CPU resources.
