i40e driver does not work due to the unsupported SFP+ module type

[mradi1]

I compiled and installed the network adapter driver for PCIe 40 Gb Ethernet(version 3.4.2). The driver is also loaded in the kernel successfully (Ubuntu 16.04). However, when I connect QSFP+ cables I am getting the following error message:

Rx/Tx is disabled on this device because an unsupported SFP+ module type was detected.

Is this because I am not using Intel QSFP+ cables?

Is there any way to allow unsupported SFP?

Best,

Hi Marjan,

Thank you for posting in Wired Communities. What is the exact model of your network adapter? If you are using Intel XL710 Network adapter, it is recommended to use validated cable, please refer to below website for the list of supported cables:

Hi Sharon,

My adapter model is: XL710QDA2, 40 GB, DUAL Port.

You mean QSFP cables from vendors other than Intel is not compatible with this interface?

Hello Alexalice,

Thank you for the outputs and details. Is the X710 adapter itself an Intel retail adapter or an OEM adapter? Please provide the markings if it is an Intel adapter. Other vendors use different modules, but AFBR-79E3PZ is not validated with any Intel X710 adapter. With the markings from the adapter we will be able to provide more information. Let us know if you have any questions. Best regards,Daniel DIntel Customer Support

So, you join the forum just to make a nonsense reply to a 3-year old thread?  You forgot to mention using beryllium wire that is encoded by default and can also be used in clothing.
