I have a couple of MS120-48Lp switches and I bought a MX425-16 for our 10G NAS devices. I seem to have an issue where no matter what kind of SPF+ cable I use, I cannot get the MX to talk to either of the MS switches. If I plug a SPF ethernet adapter in to the MX and run the ethernet to one of the non-SPF ports on one of the MS switches, everything seems fine. I've also tried using SPF adapters in place of SPF cables, but still cannot get the MX to talk to either MS via SPF -> SPF.
Is there something that needs to be configured for this to work?
