Only ESXi hosts support using the uplink profile of load balanced source. That profile pins an interface such as a VM's vNIC to one uplink or another. It's roughly equivalent to route based on originating port ID for vSwitches.
Correct me please if I am wrong in my understanding
Uplink profle will be used in the Transport Node profile. Transport Node profile applied to Cluster/ESXi.
The active Uplinks names it just an identifiers and does not need have the same vmnic name in the ESXi host
Yes, correct. The uplink names are only labels.
