Link with two 10G SFP+ SR Modules syncs with 1 G and not with 10G

[frenz]

Hi Community!

I have two MS 225 (one with 24 and the other with 48 Ports) connected via SFP+ 10 - SR Modules! On the Dashboard i can only configure "Auto", "1 Gigabit full duplex (auto)" and "1 Gigabit full duplex (forced)!

Any idea why there is no 10G Selection?

thx & BR

auto should be fine. what is the type nr on both sfp+

You can't set that because the 10GBase-X standards don't allow anything other than Auto negotiation. Hard coding the speed violates the standard. Indeed, even the 1G standards strongly suggest you use auto negotiation as best practice and not hard code speed.
