    Adapter X710 DA2 and SFP+ LR Module does not working in link mode 1GB



      I have the adapter X710  DA2 and X710  DA4, using LR SFP+ Module (Intel DUAL RATE 1G/10G SFP+ LR (bailed) FTLX1471D3BCV-IT),

      does not UP ethernet link in mode 1G between devices.


      Also can not dump the settings to the EEPROM of the SFP module in response to receiving

      Cannot get module EEPROM information: Operation not supported


      When you try to off auto-negotiation or change speed to 1000 also have

      Cannot get current device settings: No such device

        not setting speed

        not setting duplex

        not setting autoneg

      Is it possible the work of these SFP+ when using the adapter X710 DA2 in 1GB mode?

      If so, why do I have these conflicts with modules?
