I'm using a CCR1009 as "core" router, and a RB4011iGS+ as "edge" router.
Both are connected through their sfp-sfpplus1 interface.
I'm using two SPF+ modules: SFP-10G-BXU on one side (https://www.fs.com/fr/products/36351.html) and one SFP-10G-BXU (https://www.fs.com/fr/products/36353.html) on the other.
Problem is: I've to reboot the RB4011 on a daily basis because I got tons of "fcs error on link" in CCR1009 logs, every 30 seconds exactly.
On RB4011 side, I got sfp-sfpplus1 interface going down then up, again and again.
I've enabled the flow control on both sfp-sfpplus1 interfaces, without any changes.
Here's the monitor output for both SFP+ interfaces:
