CSS610-8G-2S+ Upload Speed Limited

Hi all,

I have a MikroTik CSS610-8G-2S+in and I’ve just upgraded to fiber. When I run directly to my router or through either of the non-SFP+ ports on my switch, I get my full 500 mbps up and down, but when I’m connected through 10G SFP+ port the switch I seem to be capped to about 310 mbps. Does anybody know what might be causing my SFP+ port to be limited like this? I am using factory default settings.

I solved my own problem by turning on Flow Control for both SFP ports.

thanks man,

just had the same problem down 2.5G up 500-700M enabled flow control all ports and im getting 2.5/2.5

Seriously???
OMG you guys. Is Mikrotik even testing these switches before flooding the market with them? :frowning:
