OK, so you have some switch issue.  What do you mean "see the other end",
if its back to back and boots up I assume it gets link, if you have the
address
assigned in rc.conf, and you run tcpdump on the partner do you see the arp
when it comes online, and at that point can the other side ping it?

Oh, and what is the link partner hardware?
