Optional

By default, MSTP is enabled 
on all ports after you enable 
MSTP in system view.

To enable a switch to operate 
more flexibly, you can disable 
MSTP on specific ports. As 
MSTP-disabled ports do not 
participate in spanning tree 
calculation, this operation 
saves CPU resources of the 
switch.
