[j-nsp] MX204 and copper SFP?

[Chris Adams]

Has anyone tried a copper SFP in an MX204?  With 18.1R1, the ports can
be set to 1G mode, and I can use a fiber SFP, but a copper SFP doesn't
work for me.  The router sees it, but the port shows "up" (even with no
wire connected), and it won't actually pass any traffic when connected
(both ends see transmits but 0 receives).
