Also remember that the blocked port isn't in a down state because it still
needs to listen to BPDUs to know when a topology change occurs. If it
didn't, it wouldn't know when it needs to transition to forward state, if
necessary.
Just my 0.02...

dear friend,
what u r seeing is absolutly normal you will never see
both ends of the link will never go blocking. The way
spanning tree works is one end will be blocking and
other forwarding. Remember the purpose of the STP is
to have a single path to Root bridge. Blocking on one
side o the link
delete it from your computer.

with spanning tree in blockin state has not any relation with being down, I
was surprised with some answers. What surprised me, is that one port were in
forwarding state and the port in front be in blocking state. For

Think of it like this. Each switch is supposed to block redundant ports
leading to the root bridge. Say Switch1 and Switch2 are interlinked

not that it makes any sense to me either. it would seem logical that one

Brave!! This is exactly the kind of answer I was waiting for. Just
common sense, now I understand it, and I feel like a stupid because
the answer is obvious.
Thanks Zsombor

Hello friends, I have an spanning tree question for you!
I have a lot of switches connected between them, but I have seen
something that I can not explain very well. Two of these switches are
connected using two cables:
Switch1 Switch2
Port 29
I know this do not answer your question but did you saw the timers of
Forwarding Delay in the Switches??
Regards
Victor.

I expected to see one port in blocking state (spanning-tree) and the other
in forwarding state, but suprisingly I have seen that port 30 is in
blocking
state in Switch1 but it is in forwarding state in Switch 2.

That seems right to be. The link should not go down just because spanning
tree is blocking a port.
