    Hello,

    There is Juniper ex3300-48t. He has 4 SFP+ uplink ports, but they are not detected.

    Sorry for the simple question, but do you have 10Gbps SFP's installed in the uplink slots?

    Well, its good that the ports aren't configured as VC ports, however the DAC cables aren't recognized by the system. Even unsupported cables will show up and will usually work. Are you sure they are inserted in all the way?
