How can I change the PCI device ID

[MMill17]

Folks,

I have taken delivery of a series of XL710-QDA1 nics. They are all showing a PCI device ID setting them as a backplane.

I am kinda new to this type of thing.

Is there a way to change this in the field. I wan to avoid sending thee cards back as they took over 3 weeks to get to me in the first place.

Thanks

Marc

Note the DEVICE ID is 1580 and I need it to look like the existing NICS @ 1584. I am hoping this is just a bit I can flip somewhere?

Thanks

Hi Marcmillmann,

Thank you for posting in Wired Communities. Please provide the output for ethtool -i command for item number 1 (XL710-Q1) and 2 (XL710 for backplane). Just to double check are you saying the XL710 for backplane here should be a XL710-QDA1 standalone NIC? Thanks,Sharon T

[MMill17]

That is correct. The backplane option is of no use to me.

I am hoping I can modify some setting to make it look like the QSFP option or the Converged Ethernet adaptor.

The interface for the NIC is question is not shoing up in ifconfig.

Hi Marcmillmann,

Thank you for the information. Based on the information provided the NIC is an XL710 40Gb backplane, you may refer to page 8 for the device ID Table at https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/xl710-10-40-controller-spec-update.pdf?wapkw=ethernet. You mentioned it should be an XL710-QDA1, is it possible you can provide the front and backview pictures of the NIC in question, make sure the picture includes all the white sticker that contains the serial numbers and other markings, we want to identify the NIC first so that we can check why the device ID is shown as 1580. Thanks,Sharon T

Sharon,

I am not co-located with the server. We are trying to get a juniper to open the server to photograph the NICS.

This may take 24 hours.

In the meantime can you confirm for me that I am able to use some software to change the device ID so the NIC's will support the 40GigE DAC cables we are using.

I have looked around online and the only process I can find is how to upgrade the NVM on the NIC's.

Some instructions would be appreciated.

Thanks

Marc

Hi Marcmillmann,

Thank you for the information and I will wait for your further update. I am sorry there is no tool available online to change the device ID. Let me double check for you. Thank you.Regards,Sharon T

Hi Sharon,

Here are the front and back pictures of the NIC.

Hi Marcmillmann,

Thank you for taking time to provide the picture, but I am sorry to inform you this is not an Intel manufactured network adapter, this is an OEM part from third party company. There is no publicly available tool to modify the device ID, normally the OEM vendor has their own unique device ID, we have no control over the device ID assign to the part manufactured by them. For Intel retail X710-QDA1, you should find the PBA number listed in the website on the network adapter's white sticker, https://www.intel.com/content/www/us/en/support/articles/000005612/network-and-i-o/ethernet-products.html. If you are interested to purchase Intel retail X710-QDA1, you may visit locate.intel.com or https://www.intel.com/content/www/us/en/products/find-a-reseller.html to contact our authorized resellers. Since this is OEM part, you may want to contact the OEM vendor for further support as we do not have control over the parts manufactured by third party companies. You may refer to our support option for ethernet controller website https://www.intel.com/content/www/us/en/support/articles/000006628/network-and-i-o/ethernet-products.html?wapkw=oem+network Hope the above information clarified.Thanks,Sharon T

Sharon,

Thanks for this information.

I was of the understanding that these NIC's were intel brand not just Intel Chipset.

Can I ask 1 more question?

What specifically would I use a card with the Backplane option for?

It is not clear to me what role it might play in a server.

You also hint that there is a way to flip the device ID if I have an Intel NIC. Can oyu confirm I am correct in my understanding? Just for clarity.

Thanks heaps for help.

Regards

Marc

Hi Marcmillmann,

Thank you for the reply. I will have to further check about the backplane. I want to clarify I did not hint there is a way to flip the device ID if using Intel NIC, device ID are unique ID for the NIC, but I will help double check.

Just to double check so your initial plan is to purchase and use Intel XL710-QDA1 but it turn out your point of purchase delivered the different part which third party XL710 ethernet backplane.

Thanks,

Hi Marcmillmann,

If you plan to change the device ID of your OEM NIC to Intel retail network card in order to allow the NIC to work with your 40G DAC cable, this is not supported since there is no available tool to modify the device ID. It would be best you contact the OEM NIC vendor for the supported cables. You can try out the plusoptic DAC QSFP+- QSFP + 0.5M-P-PLU cable and see if you still encounter the same issue. Further checking, The part number NIC-PCIE-1QSFP+-PLU is available in niccards.com.au. They labeled this as Intel's XL7101-QDA1 equivalent. The "Backplane" label that shows up when you run the NVM update tool is the identifier based on device ID - 1580, please refer to page 481 of datasheet ( https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/xl710-10-40-controller-datasheet.pdf. The general functionality of the NIC-PCIE-1QSFP+-PLU should be the same with retail version XL710-QDA1. Please try contacting the NIC vendor for further support about the NIC and cable you can use. Hope the above information help.Regards,Sharon T

Hi Marcmillmann,

Please feel free to update me if you have contacted the OEM NIC vendor and if further assistance needed. Thanks.Regards,Sharon T
