Dear All Expert,

I'm kinda confuse with the used of SPT port-priority and SPT path cost.

Actually when I do my IEWB vol 2 lab 11.

To influence path decision, when doing SPT.

SW1 --------------- SW2

SW1 is the root bridge

Actually SW 1 have three trunk connection to SW2, let say FA0/15,fa0/14 and
fa0/13

so the command is, SW1 should use Fa0/15 as its primary link to SW2, when
fa0/15 fail, then it choose fa0/13 and the last is fa0/14.

So, if I configure fa0/15 with spt cost 1 , do i have the same result if i
configure fa0/15 with spt port-priority of let say 15 (the default is 128
right ?)

So kinda confuse when do we have to use spt priority or cost

Thanks in advance
