I have a very weird problem with a 6506 connecting to a 3750 over single mode fibre.
The connection is single mode fibre using LX/LH Gbics. When i try to connect using the 6506 the connection shows as down/down. If i replace the 6506 with a 3560 - remove the g-bic and patch lead, and plug it into 3560 and it works.
So fibre is ok, gbic is ok, fibre patch leads are ok. I have tried various ports on the 6506 but all the same. I have one working link of similar setup working on the same card on the 6506.
