SFP+ resets every 3 minutes

[IG]

Hi,

I'm using DAC SFP+ 10G cables from fs.com, programmed as Fortinet.

They are FINISAR modules, considered valid by the FortiGate 501E and FortiSwitch1048E.

Both FGT and FSW are running 7.2.2

However, every 3 minutes, sharp, modules are reset 'to recover from error state'.

Between reset, data flows correctly.

Is there anything to be done to avoid these module reset ?

Thanks,

IG

Hello,

I have found this doc and from page 74 you have some explanation concerning ports:

Could you please tell me if it helped?

Hi,

Verify if you are using the recommended compatible transreceiver:

If you still seeing issue then on FSW port connected with  DAC SFP+ 10G, set speed 10000cr manually.

I finally managed to clear the issue : disabling dmi just make the link work without reset.

When setting speed manually, the error message about module reset is still displayed every 3 minutes but the link is not seen as disconnected/reconnected by the server end.
