While using the new vSphere 5.1 Web Client, I have got a vCenter 5.1 with Distributed Network Switches. I have enabled "VLAN and MTU health check" and "Teaming and failover health check". However, when looking at the "Status" columns, nearly all show a status of "Unknown" for all the Hosts. All my Hosts are vSphere 5.1.
I'd appreciate any advice.
