The MAC addresses of the physical NIC ports don't need to be learned, since they are being used as uplink ports between the physical switch and virtual switch.

Packets are sent and received using MAC addresses of virtual NICs (such as those of a VM or of the VMkernel) not of the physical NIC ports.
