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.

Thanks for your reply!

I switched the card configuration to 2x2x25G, tested it with cable from Cage A to Cage B, and checked that the port status is up:

Retimer B Version             : 101c.1064

With this, I've confirmed that there's no issue with the cable and card.

Since even in 2x2x25G mode, it still didn't work when I connected the card with the switch, I suspect there might be some issue with the configuration on the switch side. When I configured the switch port connected to the card, I set the rate to 25G and the FEC mode to RS for each lane (I checked the card is configured to use RS).

Could you advise what else should I check on the switch side?

Thanks,

Daehyeok

      Thanks for your reply.

      I figured out what causes the issue. Since the factory/user image on FPGA does not support auto-negotiation, I had to manually disable auto-negotiation on the switch side. Otherwise, it seems to use auto-negotiation by default, and something went wrong.

      Thanks for your help!
