Hi together,
i have trouble withe a 3850 withe the Modul c3850-NM-4-10G and the 1000BaseZX SFP. The Link stay down in the Switch. But thats not all. The SFP is working in an other Switch (3650) very well. The Port is also identified by the Switch. The transceiver detail looking also good. So i have no idea any more. Maybe you can give me some advices for troubleshooting or (that would be great yeeaahhh) a solution.
Thank you
Edvard Franke
and here are the details about the 3850 Switch
