We recently (a few months ago) put two 6509s into VSS mode and had many teething problems. One of the problems we had was random ports on switch 2 of the pair came up in err-disabled mode after a reboot. We somehow fixed them by combinations of shut/no shut, reseating or changing SFPs, etc.
Two days ago we saw half of the ports on one card were in err-disabled mode due to udld errors. We cannot find a way to bring them back up (tried udld resets, etc) and think it's really strange that it's a block of ports on the same card. Also it's strange since last time we had this problem it was on different cards (switch 2 as well though).
See below Te2/3/5-12 are in err-disabled mode. All other ports are fine. We highly doubt a physical problem with fibre and SFPs. Initially suspected the line card, but happened on different cards last time.
Is there some bug anyone is aware of? Software or physical issue?
Thanks in advance,
Paolo.

What do these err-disabled ports connect to?

I have had a similar problem but with a Catalyst 6800-XL VSS Pair.
So any updates on what may be causing this, faulty hardware or IOS Bug ?

RMA of the card fixed the issue in my case.

Currently hitting the same issue, ports 5 to 12.
We did a RMA on the CFP with no success. Did you find what caused the problem ?
