How to disable auto-negotiation of X552

[raon]

My ethernet device is "X552 10 GbE Backplane".

I need to disable auto-negotiation to link up another 10GBASE-KR device(Not ethernet switch), which is the auto-negotiation is 'off'.

The speed is needed 10000 bps.

My O/S is CentOS 8 and a device driver is ixgbe-5.12.5

I tried the following command but the setting is not changed.

        ethtool -s eth1 autoneg off speed 10000 duplex full

I would like to know how I can disable the auto-negotiation.

The follwoing is a ethtool log of my device. 

[root@localhost ~]# ethtool eth1

Hello raon,

Thank you for posting on Intel Ethernet Communities. 

We would like to Provide you some of our steps on enabling or disabling the auto-negotiation.

To enable or disable auto-negotiation:

# ethtool -s <ethX> autoneg <on|off>

Then to set the speed and auto-negotiation setting....

The ethtool –s command can be used to change the current settings by defining the values for “speed,” “duplex,” and “autoneg” in the following format

sudo ethtool –s [device_name] speed [10/100/1000] duplex [half/full] autoneg [on/off]

Example: Set the speed at 1000Mb/s, the duplex mode to ‘full’ and the auto-negotiation to ‘on’ the command would be:

sudo ethtool –s enp0s3 speed 1000 duplex full autoneg on

The ethtool [device_name] command can be used to confirm that the changes have been applied.

In case this does not work, please advise us if you are using a custom mother board for this, if not please provide us the exact model of your mother board and the processor that you using. 

If you have questions or other clarifications please let us know so we can help you further

Awaiting to hear from you soon, should there be no response from you, I’ll make sure to reach out after 3 business days. Thank you and have a nice day!

Best regards,

Zigfreid I.

Hello raon,

Thank you very much for advising us and for providing the information that we have asked. As per checking on your concern, this is more of a processor and board feature rather than an ethernet connectivity feature. Please allow us to route this query to the concerned team instead for proper assistance. They will get in touch with you as soon as possible.

Please feel free to contact us if you need any assistance from Ethernet support team. Thank you and have a good day!
