Port up/up but no mac-address on interface

Has anyone ever seen a network cable be the cause of a layer 2 issue when your interface on your switch is UP/UP, no input errors

you have outgoing packets however no input packets from the server? From my experience when your you're interface is up/up and

clean and you see no incoming packets your looking at an server issue - may it be nic / config or other issue.

I guess you can have an issue if you pins on your jack get bent/crossed but I would assume you would see errors.

BTW -- Server is an ELM 6000 McAfee Security  Manager

Your thoughts!

Does the server have multiple nic cards (an alternate path or default route)?

If it had only a single one and not working, can you connect another device (i.e. a laptop) to the port to verify the port itself is working properly?

Is there a possibility of a speed configuration issue?  Both ends should be fixed/same or auto config.
