hi every body!

I have this simple question

let say we have three switches : sw1,sw2 and sw3.

sw 1 is root switch. They are connected serially.

c=1 c=1

(sw3) f0/2---- f0/2(sw2) f0/1-- f0/1 (sw1)

where "c" represents path cost

sw2 has f0/1 as root port

what would be f0/2 port of sw2 and f0/2 port of sw3 i.e designated port,blocked port,?

thanks alot !

what would be f0/2 port of sw2

Designated Port

and f0/1 port of sw3 i.e

Root Port.

SW3 sees SW2 on F0/1 as the path towards the root hence the port connected towards SW2 will be the root port.

SW2 will be the designated port on F0/2 as it has a path towards the root (transit switch).

SW1 will have a designated port on F0/1 and SW2 will have a root port on F0/1
