Open a Cisco TAC case and upload a Nexus 9000 tech support (`tac-pac`) to investigate further.
Is "port security" enabled on these ports? Does this port double as a LOM/IPMI port? What driver is being used `ethtool -i eth#`? Any OS bonding? Any switch port-channel/vPC?
That NIC chipset is a few years old so it's not like that NIC/OS/switch is a combo that hasn't been tried/tested.
