Hi - I am going to have to contact QNAP in Taiwan directly. This customer has multiple large QNAP systems - all with 25G SFP28 cards. There is no issue with QuTS h5.2.4 - the FEC settings are all there. But in QuTS h5.2.5 - nope - it’s gone. I guess SFP28 is such a small user group, and there are so many things to test for - that they did not bother to check this.
