Intel X710 (X710DA4) link Down

Hi!

Neededhelp!

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

It is in the caseof a loopbetween the interfaceson the X710:

@ubuntu:~$ sudo ethtool p2p1

        Supported ports: [ FIBRE ]

        Supported link modes:   1000baseT/Full
