- Can you please open up a support ticket? Use portal.nutanix.com for NX or SX series hardware, and the respective OEM support site for Dell XC or Lenovo HX.
That said, we do have a recommended switch configuration document for Nexus switches, posted here: https://portal.nutanix.com/#/page/kbs/details?targetId=kA032000000TT4kCAG
It sounds like there might be a mismatch between how the switch is configured, and how the vSwitches on the host are configured.
For example, if you've set up Cisco VPC on the switchports, but have not setup LACP or static etherchannel on the ESXi side, it will cause problems like you describe.
