Running a vCenter 6.7 U3 / ESXi 6.7 U3 environment with several vDS, we are seeing abnormal behavior in vCenter where the virtual switches view is not showing any physical NICs attached to the uplink ports. All indications seem to be that networking wise, it is working normally on the backend and that this could be an issue with the web interface. Any suggestions on how to troubleshoot? Attached is a screenshot of the issue I am describing. Thanks.
