Auto-negotiation always off on OL7.3 Linux with "X710 for 10GbE SFP+"

[FZhou4]

Hello,

The full product name is:

Ethernet controller: Intel Corporation Ethernet Controller X710 for 10GbE SFP+ (rev 01)

I have a weird problem. My Intel card always shows Auto-negotiation : off .

1) Confirmed network switch is set to on;

2) When I set it manually, it prompted error:

[root@auspldccasssb01 ~]# ethtool -A em1 rx on tx on autoneg on

Hi iamfragon,

Thank you for posting in Wired Ethernet Community.We're currently checking your concern and will post an update as soon as possible. Regards,Vince T.Intel Customer SupportAgent under contract to Intel

Thanks Vince.

Any update on the analysis?

Hi iamfragon,

If you're using SFP+ DAC connection, it only support 10Gbps connection therefore auto-negotiation is not needed.Please let us know if you have other assistance needed.Regards,Vince T.Intel Customer SupportAgent under contract to Intel

Thanks a lot Vince.

We do use SFP+ DAC connection so it should be a normal behavior.

One more thing just a little bit confuse. If you don't mind. ------

From your statement below:

If you're using SFP+ DAC connection, it only support 10Gbps connection therefore auto-negotiation is not needed.

But when I query NIC status, it shows 1GB supported. Any idea the possibility reason?

thanks again Vince.

Hi iamfragon,

Let me double check this one. kindly share the markings of your X710. The markings is located in the white sticker on the physical adapter.We have a retail version of the X710-DA2 with SFP+ DAC connection, the ethtool result is aligned with the statement that it only supports 10Gbps.Settings for enp1:Supported ports: [ FIBRE ] Supported link modes: 10000baseT/Full Supported pause frame use: SymmetricSupports auto-negotiation: No Advertised link modes: 10000baseT/Full Advertised pause frame use: NoAdvertised auto-negotiation: NoSpeed: 10000Mb/sDuplex: FullPort: Direct Attach CopperPHYAD: 0Transceiver: internal Ethtool output:driver: i40eversion: 2.4.10firmware-version: 6.01 0x80003483 255.65535.255Regards,Vince T.

I'm working remotely so it's not easy for me, to get the markings. However, I can provide as much detail as possible.

From the output of Linux hardware tool, I got that we have an "I350 Gigabit Network Connection" integrated with X710, means it is a combination card of X710 & I350 (GB support only).

i.e.

*-network:0

description: Ethernet interface

product: I350 Gigabit Network Connection

*-network:0

description: Ethernet interface

product: Ethernet Controller X710 for 10GbE SFP+

do you think it be the reason?

thanks Vince!

BTW, do you mind to share the Linux kernel release and version? I saw the both driver version and firmware version are newer than us:

[root@auspldccasssb01 ~]# ethtool -i em1

driver: i40e

version: 1.6.27-k

firmware-version: 6.00 0x8000374f 18.5.17

Hi iamfragon,

We're looking into the reason as to why you have 1000baseT/Full in the ethool output. The https://downloadcenter.intel.com/download/24411/Intel-Network-Adapter-Driver-for-PCIe-40-Gigabit-Ethernet-Network-Connections-Under-Linux- driver and https://downloadcenter.intel.com/download/25791/Ethernet-Non-Volatile-Memory-NVM-Update-Utility-for-Intel-Ethernet-Adapters-710-Series-Linux- firmware we have is the latest for Retail version of X710-DA2. Please share the system name and model where you have this X710. This information might help us determine if your X710 is integrated on the system or installed separately. Kindly refer to our uname -r output below:3.10.0-693.el17.x86_64Regards,Vince T.Intel Customer SupportAgent under contract to Intel

Hi iamfragon,

Based on your firmware information, you have an OEM version of X710. The OEM might have customized drivers to alter features of the card. We suggest to double check with them regarding your concern.We also noticed the "Port" value in your ethtool shows as "FIBRE" while in our lab, it shows as "Direct Attach Copper", This might be the reason why we have different values in the Supported link modes.Regards,Vince T.Intel Customer SupportAgent under contract to Intel
