did you tried gig-default neg-off on the interface ? 

are you really getting light on the fibre ? (can you test if you got loss, 
orso?)

I am working on a new deployment in Verizon data center in Europe. We have an 
MLX with LX optics. Our two routers link fine but when we connect the uplinks 
to Verizon, no link. I have tried everything I know such as rolling 
xmit/receive, changing negotiation, etc. The config is REALLY simple, just an 
IP address, route-only on the interface, and no spanning-tree. Links fine 
between MLX units, will not link to Verizon's cisco. 

I recall having this same problem with vendors using Cisco in the past (Level3, 
Savvis UK) and it took them a while to figure it out but they have always done 
something that allowed things to work eventually. Anyone have the magic clue I 
can pass to VZB to make this thing work?
