VLAN Settings (Virtual Local Area Network) A VLAN is a collection of switch ports that make up a single broadcast domain. You can configure a VLAN for a single switch, or for multiple switches. When you create a VLAN, you can control traffic flow and ease the administration of moves, adds, and changes on the network, by eliminating the need to change physical cabling. On VLAN settings, there are two main settings, VID Table Setting, Port VLAN Setting, and Port Egress Setting. When you select VID Table Setting, press "Add new VID" to create new VID group, from port 01 ~ port 48, select Untag Port, Tag Port, or Not Member for each port.
