AF24 CRC errors

Hello!

For now We have 24 Airfiber 24 links and on all swiches  connected to DATA port from both sides of links we see CRC errors 

switches are dlink dgs-1510/me, 3000, 3120, 3200, cisco linksys gigabit switches - its 100% not switch problem

We tryed to change poe, cables, airfibers... nothing helps.as i remeber this problem started after version where multicast filter was introduced....i dont remeber version, may be 1.5 or something like this

on all of these airfibers inband management is disabled and 4.0.3 firmware installed

Dear UBNT support team please please fix this problem.

We can give to your support remote access to devices if needed or send some diag data
