I have attached the sho run all output. Any idea why I can't get an link out of this? Thank you very much for your time.

Is the SFP installed in the device a Cisco labelled product or a third-party labelled device? Cisco SW runs a check to verify the SFP is compatible before allowing it to operate.

I am assuming even thought the website claims that the FTLX8571D3BCL is Cisco compatible, that it is not. And the
"sho interface ethernet 1/15 transceiver" repsonse "cisco id is --" is proof of that?
I saw some other FTLX8571D3BCL online that had -cs added to the model number. I am guess this difference in model number has caused our failure? I have no clue. All I know is it won't link.
Nowhere on the device does it say Cisco. Thank you.
