3.1.2.2 LAN & VLAN
This section provides a brief description of VLANs and explains how to create, and
modify virtual LANs which are more commonly known as VLANs. A VLAN is a group
of ports that form a logical network under a certain switch or router device. The ports
of a VLAN form an independent traffic domain in which the traffic generated by the
nodes remains within the VLAN.
The VLAN function allows you to divide local network into different “virtual LANs”. In
some cases, ISP may need router to support “VLAN tag” for certain kinds of services
(e.g. IPTV) to work properly.
This Device supports port-based VLAN and tag-based VLAN. You can select either
one operation mode and then configure according to your network configuration.
3.1.2.2.1 Port-Based VLAN
A port-based VLAN is a group of ports on a Ethernet switch or router that form a
logical Ethernet segment. There are four LAN ports and up to eight virtual APs in this
device, so you can have various VLAN configurations to organization the available
LAN ports and virtual APs if required.
By default, all the 4 LAN ports and 8 virtual APs belong to one VLAN, and this VLAN
is a NAT type network, all the local device IP addresses are allocated by DHCP
