Description
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.
