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 (https://www.intel.com/content/www/us/en/programmable/documentation/zsf1588015530773.html) to install the required runtime stack. I am trying to use it as a basic NIC with a 4 x 25G configuration.

When I checked the status of Retimer using "sudo fpgainfo phy", it showed that the all four ports are down:

-bash-4.2$ sudo fpgainfo phy

Retimer B Version             : 0000.0000

On the switch side, I could see the port status for all four lanes is down:

-----+----+---+----+-------+----+---+---+---+--------+----------------+----------------+-

Could you let me know how to activate the ports?

Please let me know if you need any further information.

Thanks,

    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.
