    Default Compatibility Between 2 different interfaces

    I am not sure if this thread should belong here.
    Anyway, I work in a data centre.
    I have a switch which is using SFP (1G) and another wich is using SFP+ (10G).

    Is there any way for these two to be compatible without switching SFP.
    They are only designed to use this particular type of SFPs.

    There is no auto-negotiation w/ the 10G. If your switch/optic will let you hard set the interface to 1G, it will work. I've done this with Nexus 5Ks a number of times.

    If I am not mistaken I believe the SFP+ can operate at both 1G and 10G so as long as you set the proper speed/duplex on both sides it should work.

    It depends on the SFP model number; some can have the speed set; some cannot. I personally have not seen any fiber SFPs that can have speed set but I know you can with standard copper GLC-Ts. I would say probably not.

    An SFP+ port may be backward compatible with SFP modules, so you can use a 1Gb SFP module in the SFP+ port if this is the case.
