You do it per vlan,
remember that forwarding "includes" the listening
and learning states. So depending on what you are
trying to accomplish you'll need to take this into
account that you have a multiple of 2 in the figure.
So..if this were a lab question saying to "reduce
the forwarding time on these ports to whatever" then
I would just check to see what VLAN's are assigned
to those ports and then go from there. In the real
word, RSTP in my view is the way to go...faster
