Hi Team 

I had case below. I using E810 XXVDA2 25G connect to switch Cisco Nexus 93180YC-EX using Module M14MK 10/25G --> but no up link

Swap to using DAC cable 25G system can up link normal 25G. Could you help to check and advice. Thanks so much

Hey LeXuanTinh,

So did this allow you to use a fiber cable at 25GB? I actually am running the same switch, E810 and Module as you. I think the only issue I am going to have is that I am running this on ESXi 7.0, so I am not sure how I can change the FEC.

Thanks for your follow up!

Hi Friend 

After change link FEC and disable Auto-negotiantion, my system uplink 25G. you can search the guide change FEC on your switch by title " Cisco ACI Auto-Negotiation and Forwarding Error Correction "  on google. I using esxi 6.7 when i change FEC not affect to my OS
