We have had a few strange unidirectional link problems and I thought
that I could detect them using UDLD. So I thought I knew how it
worked. I
I have a 6500 with a gig SFP LH mod connected to a 3750 with the same
SFP. I enabled UDLD AGGRESSIVE mode on bot ends and they both
reported seeing each other as neighbors.
So I thought that if I disconnected one of the fibers that the UDLD
would detect the unidirectional transition but instead both ends just
reported link down.
I thought that breaking on side of the fiber would only bring down one
end LINK since the other still thought it was connected.
I then disabled the UDLD and disconnect the fiber again and still had
both ends show link failure.
Q> So why does both ends go down? Is this a new code feature for
gig fiber ports or did I miss something?
