Larry,
thank you for your feedback. I have found that the nonegotiate is
considered just a temporary workaround in this cisco document:
www.cisco.com/networkers/nw00/pres/2807_6-28.pdf
Anyway I'll check the g-bics.
Thanks again
Luca

I have seen this problem before.
Basically you have a layer 1 problem thus, your fiber.
Some possible problems to look at:
1. Is your fiber longer than IEEE standard?
With GBIC-SX, 550m for multi-mode
With GBIC-LH, 300m for multi-mode
With GBIC-LH with modal cable, 550m for multi-mode
With
we use the non negotiate mode on all our trunks...we dont
consider it a work around..
have you checked your g-bics at both ends ?
