Link status on BD-NVV-N3000-3 card

Hello, I've installed a BD-NVV-N3000-3 card on our server and connected it to an Intel Tofino-based 32-port 100Gbps switch using a QSFP+ cable. And I've followed the instruction in the user guide (...

    Hi @Daehyeok_Kim

    Thanks for your update on your debug status. Im glad to know that we have ruled out the cable or card issue. For the switch related queries, I am not the subject matter expert. Could you file a separate forum thread on the Ethernet products Forum (https://community.intel.com/t5/Ethernet-Products/bd-p/ethernet-products). They will be able to guide you from there. Appreciate if you can put in the link to the new thread for the benefit of others who face similar issue.

Please follow the below debug steps:

1) Check if you are using the correct board OPN.

BD-NFV-N3000-1 :Production 10 GbE

OR

BD-NVV-N3000-2: Production 25 GbE

You should not program the BD-NFV-N3000-1 (Production 10 GbE) with a 25GbE image, vice versa. You cannot use the cards interchangeably.

2) Connect the QSFP cages with a loopback module. Run “fpgainfo phy” and see if all ports are UP.

3) If Step 2 is passing but failing only when you are connecting the card QSFP to other QSFP cage on other devices.

Thanks for your reply! I have some follow-up questions.

1) I am using BD-NVV-N3000-3 and haven't programmed the board with other images. I followed the instruction up to section 4 (https://www.intel.com/content/www/us/en/programmable/documentation/zsf1588015530773.html#phn1588111278439).

Could you let me know how to verify which version is loaded? Also, what does OPN stands for?

2) By the "loopback module", are you referring to the module shown in Fig. 4 (https://www.intel.com/content/www/us/en/programmable/documentation/zsf1588015530773.html#xzd1588094394268)? Is it included in the original package?

Thanks,

Daehyeok

    1) Thanks. I think you have answered me.
    OPN refers to BD-NVV-N3000-3
    Version loaded refers to the MAX10 build/NIOS version + Bitstream ID.

    2) Yes, loopback module as shown in the link you referred: https://www.intel.com/content/www/us/en/programmable/documentation/zsf1588015530773.html#xzd1588094394268

    No, it is not included in the package. You will have to purchase it separately from the module makers.

    If you do not have a loopback module at hand, you can order for 2 (one for each cage). It will be useful for future debugging as well. Meanwhile, you can try connect the ethernet cable from QSFP cage A to cage B, and check fpgainfo phy. If port is up, then it would be the connection to the external switch issue. If it is still down, it would either be a card or a cable issue. To rule out if it is a cable issue, you will definitely need a loopback module.
