Hi, 

 

I tried to set the speed at 100Mbit/s and autonegatiation off on a i225 under linux using ethtool.

I am running these commands:

 

/* Check out the link/autoneg/speed status */

root@board:~# ethtool enP1p6s0 |grep Auto-neg
Auto-negotiation: on
root@board:~# ethtool enP1p6s0 |grep Link
Link detected: yes
root@board:~# ethtool enP1p6s0 |grep Speed
Speed: 1000Mb/s

 

/* Set the link/autoneg/speed to desired values */

root@board:~# ethtool -s enP1p6s0 speed 100 autoneg off

 

/* ReCheck out the link/autoneg/speed status */

root@board:~# ethtool enP1p6s0 |grep Auto-neg
Auto-negotiation: on
root@board:~# ethtool enP1p6s0 |grep Link
Link detected: yes
root@board:~# ethtool enP1p6s0 |grep Speed
Speed: 1000Mb/s

 

Please Note that the ehttool command runs well on a i210 device.

 

Thanks in advance for your answer

Hello,  @bsan83:

Thank you for contacting Intel Embedded Community.

We want to address the following questions to understand this situation:

Could you please clarify if this request is related to an Intel® Ethernet Controller I225-V design developed by you or is a NIC or add-in card developed by a third-party company?

What is the name of the manufacturer, the part number, and where we can find the information if this request is related to a third-party design?

Could you please let us know the Operating System (OS) related to this situation and its version?

What is the "ethtool" related to this situation, its document number, and its version?

We are waiting for your answer.

Best regards,

@CarlosAM_INTEL.
