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.
TL-R470T+ provides the Port VLAN function, which allows you to create multiple logical VLANs for the
LAN ports based on their port numbers.

The User Group function is used to group different users for unified management, so that you can

group.
