Users with more advanced LAN setups may have requirements for each of their hosted devices to operate on a VLAN. VLAN tagging is a method through which more than one VLAN is handled on a port. VLAN tagging is used to tell which packet belongs to which VLAN on the other side. To make recognition easier, a packet is tagged with a VLAN tag in the Ethernet. Appropriate VLAN tags can be set on the UC Portal.
