Switch 1 STP root and Switch 2 is access switch.
Switch 2 gig 0//25 : Fiber port (1000Base SX SFP) <-- Trunk--> Switch 1 gig 3/10 Fiber port (1000Base SX)
Switch2 gigEth 0/24 : <--- Trunk---> Sw1 gigEth 4/10
Will STP makes the Fiber port (gig 0/25) as forwaring port on SW2 or gigE (0/24)?
Thank you Jon.Thats what I guessed. Is there anyway I can make the fiber port to be the forwarding and gig eth blocked?
Yes, you can alter the port cost so that the cost of the path to root is not the same -
