VLANs can be configured at the port group level. The ESXi host provides VLAN support through virtual switch tagging, which is provided by giving a port group a VLAN ID (by default, a VLAN ID is optional). The VMkernel then takes care of all tagging and untagging as the packets pass through the virtual switch.
