We are trying to connect our ConnectX-6 and ConnectX-7 cards to our SONiC switch, but we are getting a negotiation failure error when they are connected
Assuming you have NVIDIA support entitlement for the adapter cards, please open a support case on our portal and we can then help troubleshoot the issue.
Details about enterprise support and how to engage with support are detailed at https://docs.nvidia.com/ai-enterprise-support-and-services-user-guide.pdf.
