3.1.7.6Port VLAN
A VLAN (Virtual Local Area Network) is a network topology configured according to a logical scheme rather than the physical layout, which allows you to divide the physical LAN into multiple logical LANs so as to control the communication among the ports.
The VLAN function can prevent the broadcast storm in LANs and enhance the network security. By creating VLANs in a physical LAN, you can divide the LAN into multiple logical LANs, each of which has a broadcast domain of its own. Hosts in the same VLAN communicate with one another as if they are in a LAN. However, hosts in different VLANs cannot communicate with one another directly. Therefore, broadcast packets are limited in a VLAN.
Choose the menu Network→Switch→Port VLAN to load the following page.

Tips:
●The Port VLAN can only be created among the LAN ports.
●The change of DMZ status will affect the configurations of Port VLAN. You're recommended to check or reconfigure the Port VLAN if the status of DMZ is changed.
3.2 User Group
The User Group function is used to group different users for unified management, so that you can perform other applications such as Bandwidth Control, Session Limit, and Access Control etc. on per group.
