Try change POE injector. If you use this http://routerboard.com/RBPOE
The biggest source of the problem ...
LAN, FTTx, Wireless. ISP operator

IF you use NSTREAM mode, could you try with the NV2 mode and report back please for start? :)

When I had in bridged mode wan1 and eth1 on my RB411 and I had Nstream, I was in the same situation as capitan.
When I afterwards picked the NV2 protocol, everything was working grate.
After that, i only use NV2 nomatter what. :D
I don't know what is common with these things, I'm just writing you down what I have encoded with my RB411AH routerboard. Maybe a coincidence?.

Another ethernet flapping on the SAME model boards, I encoded it with the PSUs of them.
When I change the PSUs, everything was OK.

EDIT: You could encode the same problem, if you are on a mountain with HIGH RF levels from FM and TV stations.

There is no definitive cause for that ethernet port flapping:

and the MT is not seeing anything broken with it...

our solution is using the SFTP (not FTP) cable with the SFTP connector...
and if budget ok, use the ubnt 24 watt poe instead of using mikrotik power adapter + poe.

then you can enjoy your time.
