How to activate 1g SFP ports [29-32] on X460-G2-VIM-2X-B-1 v15.7.1.4

I have the ports enabled but they don't pass traffic when connected to a Junipr mx80.

The previous engineers said they didn't use the 4 dedicated SFP ports because they couldn't get them to work either.

I read somewhere that all the previous combo SFPs had to be used before the dedicated SFP became available.

I am quickly running out of optical ports so I really need to figure out how to use these 4 ports.
NOTE: Nothing is plugged into the ports at this time.

I will double check the auto-negotiate/speed/duplex settings again.

The SFP I use will support 100m/1000m. Could that be a problem? I noticed in the documentation that the last 4 SFP front ports are 1g only.

24 front panel ports of 10/100/1000BASE-T (ports 1-24, four of which are shared with SFP ports), four combo (shared) SFP ports, and four dedicated SFP ports (100/1000BASE-X), and four ports of 1G SFP (ports 29-32).
