I guess I just figured they would be bridged in the radio, and then I
would be smart enough not to created a bridge loop. Now I have no way
of knowing if I have a good Ethernet cable until I go to enable it and
find out it's not working.
This is only my 2nd EPMP3000 in the air, but it acts the same way as my
last EPMP3000 radio. I installed the new radio on the tower. It ran
perfect for about a week, then started having Ethernet problems. My
first install, the Ethernet problems cleared up on their own after about
3 weeks. I'm curious if this one would do the same. But since I have
to have the copper Ethernet Disabled now that I ran the fiber, there is
no way of knowing.

That wouldn't be unprecedented. That's how Telrad Compact works. It

have to disable a port on your switch.
I'm not sure what the rationale for that is, but I can guess. The
alternative's would be bridging the ports together or having a
software selector for which port is your data port. If the ports are
bridged (as they are in Trango Apex Lynx for example) then connecting
both at once can create a switch loop. If the ports are software
selected there has to be a default. Suppose the default was copper,
but you only plugged in the SFP....a factory default then requires a
tower climb to fix.
So having the device pick one port automatically removes some
opportunity for self inflicted pain. I might rather be able to
configure the copper as an OOB managment port, or use it to feed
another device, but I think this way isn't insane either.

I just hooked a fiber line up to one of my EPMP3000 AP's that was
having Ethernet problems. But i didn't have a chance to test it on
the bench first. I don't really see any settings to change the
Copper/SFP independently. If the Copper interface is up, then it
will choose that over the Fiber interface? That's what it's acting
like. The Copper has to be physically down, or the SFP Won't pass
traffic. Am I missing something, or is that normal.
