At this time, UDT is unable to differentiate between an uplink port to a VM host (with multiple VLANs and MAC addresses) and an uplink to a switch or router, so both are treated as a trunk port and therefore MACs, IPs and Hostnames for VMs are not shown. VMs are also displayed as indirectly attached to the network and therefore do not show what port they are connected to.
We team multiple NICs on VM hosts and then distributed those connections between two switches for redundancy, so to be able to know which NIC/Switch a VM is using would be helpful when troubleshooting issues.
