    Intel X710 (X710DA4) link Down






      Needed help!


      I have the adapter X710DA4 and  X710DA2, and using LR SFP Modules Intel DUAL RATE 1G/10G SFP+ LR (bailed) FTLX1471D3BCV-IT.

      There is a problem for inclusion in Juniper switch, link is down 1GB mode between devices.


      Try to off auto-negotiation or/and change speed to 1000 get:

      @ubuntu:~$ sudo ethtool -s p2p1 autoneg off speed 1000 duplex full

      Cannot get current device settings: No such device


        not setting speed

        not setting duplex

        not setting autoneg


      @ubuntu:~$ sudo ethtool -i p2p1

      driver information:

      driver: i40e

      version: 1.5.16

      firmware-version: 4.42 0x80001921 0.0.0

      bus-info: 0000:0a:00.0

      supports-statistics: yes

      supports-test: yes

      supports-eeprom-access: yes

      supports-register-dump: yes

      supports-priv-flags: yes






      It is in the case of a loop between the interfaces on the X710:

      @ubuntu:~$ sudo ethtool p2p1

              Supported ports: [ FIBRE ]

              Supported link modes:   1000baseT/Full


              Supported pause frame use: Symmetric

              Supports auto-negotiation: No

              Advertised link modes:  10000baseT/Full

              Speed: 10000Mb/s

              Duplex: Full

              Port: FIBRE

              PHYAD: 0

              Transceiver: external

              Auto-negotiation: off

              Supports Wake-on: d

              Wake-on: d

              Current message level: 0x0000000f (15)

                                     drv probe link timer

              Link detected: yes


      Need a solution what to do to make the link between the X710 and Juniper stood up to the work, if possible.
