FGT 3100D not supporting 1G SFP

Hi All,

I have a FortiGate 3100D FW in my lab, and in the data sheet, I could see this has 31 x 1/10G SFP ports, but 1G SFP will not work here. I troubleshoot with a third-party SFP only, but the third-party 10G SFP is working and the 1G SFP is not working. Hence, kindly help me to how to troubleshoot this.

Thanks and regards,

Hello Thoufik,

I would recommend to check whether speed is set:

config system interface
edit <port number>
set speed 1000full
next
end

and whether SFP is supported

Hi @abarushka,

Thanks for the response.

I have changed the speed of the interface but however it was not working.

Could you please suggest any other ways?

Hi @AEK,

Hi

I have no idea, however I tried 1G Cisco SFP on my FG 100D and it worked fine. But I guess it depends on FGT model and SFP model.

I also guess Fortinet will not support any related issue if you use third party SFPs.
