Hi All We've noticed a lot of RX FCS errors between two 10G Fibre SFP+ CRS317 <-> CRS317. We only see the errors on one side and they cause packet loss, port drops, STP etc etc etc. We're running RouterOS (SwOS is not an option). We've replaced SFP modules, patch leads and tested the fibre between the two points. Pretty confident it's not the modules or cabling. Now I've come across this: https://forum.mikrotik.com/viewtopic.php?f=2&t=141633&start=100 This seems to suggest it's a known problem in the CRS317 line, although most people here are talking about between 317 and 328 switches, I'm seeing in between two of the same 317's (albeit one about a year newer) Is anyone else seeing problems like this? Surely we're not actually dealing with a company here which is still actually selling this stuff knowing it has a problem..... Shane

Hi Mike That does seem like my only option. However, most of these switches are less than 6 months old. Which means I purchased them after Mikrotik became aware of the problem, yet they still sell them! Many are also in production meaning we need new ones before hand. Crazy. This company has some answering to do. We’ve decided to move away from Mikrotik. New Cisco equipment is ordered and the Mikrotik gear is headed for the bin. Buyer be ware!

Hi Shane, Totally understand the annoyance factor here - but I wouldn't send them to trash just yet. Chances are good that future software update will work around the issue, and if not they can be repaired to be fully functional. Hardware problem is not always a manufacturing or design flaw, and actually it is usually a damage in transit issue, for example drop shock on one edge can cause dislodge of socket mounted component, or apply stress to externally exposed parts that crack the PCB connection. Such 'damage in transit' is typically addressed by a change in manufacturing process or enclosure design or amount of solder used on affected parts. Such problems are not always obvious causes when they are first discovered, and so it is not /necessarily/ an intentional 'sale of dodgy equipment that have known issues' :-} If alternative vendor products are affordable and offer improved confidence and reliability, then of course it makes sense to use them! :-} Cheers! Mike.

Removing the connections between CRS317's has solved all our problems, so we're now very confident that this issue being discussed in the forums (for nearly a year) is the cause. Anyone considering purchasing - think it through. I don't recommend them.
