Check for a duplex mis-match on the interface.  It is a fairly well know
issue that Sun and Cisco's don't auto negotiate well.  Hard code the speed
and duplex on preferably both sides, and you should the FCS errors go away.

Thanks Frank. You wouldn't happen to have sun boxes giving you problems?

Hello. I'm experiencing huge amounts of fcs errors on my switch.
3/1 91521 fcs errors
3/2 28078 fcs errors
These counters were cleared Friday. I understand that these errors are
usually media related. I've swapped cables so far which has not seemed to
help. I can tell you there is a  sun e450 and e250 attached to these ports.
Do you know of any interoperability issues with the cat 5505 and sun NICS?

Thanks In Advance,
Dave
