Did you replace the cable with a known good one? Or with the one that your predeccessor replaced because he jammed it in the door and had problems with bad FCS.... :) just kidding!
Make sure you replaced it with a new or known good cable, rather than a "spare".

I appreciate the feedback. -----Original Message----- From: Priscilla Oppenheimer [mailto:[EMAIL PROTECTED] Sent: Friday, February 28, 2003 2:05 PM To: [EMAIL PROTECTED] Subject: RE: FCS Errors between 2 5500's [7:64072] Is there any chance there's a duplex mismatch? I doubt anyone uses half-duplex on Gigabit Ethernet, so this may be a clueless suggestion. However, that's the symptoms you would get. The side set to half would sense someone else sending while it was sending, stop, backoff and try again. The result of the thwarted transmission would be a runt with an FCS at the recipient. Since you replaced the fiber already, I guess you better start swapping hardware. But it's really hard to tell which side to replace. The sender could be sending bad data. I think that's more likely than the recipient having some problem with receiving the data and reporting FCSs. So I would start on the sender (the one not reporting errors, despite possibly being the culprit.) Are there any media filters or other components in this link that could be causing a problem??
