I have tried all sorts of SFP and SFP+ modules in the RB4011 and none of them worked without Auto Negotiation disabled and set it to 1G duplex. I have now bought 3 pairs of 10G SFP+ modules and cables unsuccessfully trying to establish a 10G link. I bought the only cable that is said to be compatible on this page https://wiki.mikrotik.com/wiki/MikroTik ... lity_table the S+AO0005.
What makes this more frustrating is that the moment I plug this into my RB2011, there is immediate port activity.
If anyone has any solutions or suggestions I'm more than open.
I've looked through this thread which is the only and closest I could find.
