[j-nsp] QSFP+ to SFP+ adapters

[Richard McGovern]

Chuck is not running Fusion of any kind.

Chuck, I "think" we are going to eventually certify (not re-sell) one of these adapters, most likely Mellanox.  We cannot certify all, that is for sure.  Hopefully at that time, we can add whatever might be needed to get DOM support, if possible.

Regards and FYI, Rich

I’d rather be lucky than good, as I know I am not good
I don’t make the news, I just report it

    We have used the ones from flexoptix
    
    They tend to work correctly, but like you mentioned you lose the DOM and also the optic partcode may not display correctly on a show chassis hardware.
    
    Apart from that work quite well.
    
    Note:  don't bother trying to use these for a fusion setup on the satellite side as it doesn't work.
    They can work on the AD device with a native 10GE port on the satellite, but using them on the satellite in a 40/100GE port  as a 10GE uplink, is a no go.
    
    will

    Has anyone tried using QSFP+ to SFP+ adapters such as this one?  What software versions have you tried?

    I'm testing these on QFX10002-36Q with 17.3R3-S7.2 and SFP+ 10G-LR modules.  The links come up and pass LLDP and IP traffic, but DOM doesn't work:
