Virtual LANs (VLANs) are logical, independent workgroups within a network. These
workgroups communicate as if they had a physical connection to the network. However,
VLANs are not limited by the hardware constraints that physically connect traditional LAN
segments to a network. As a result, VLANs allow the network manager to segment the
network with a logical, hierarchical structure. VLANs can define a network by application or
department. For instance, in the enterprise, a company might create one VLAN for multimedia
users and another for e-mail users; or a company might have one VLAN for its Engineering
Department, another for its Marketing Department, and another for its guest who can only use
Internet not Intranet. VLANs can also be set up according to the organization structure within
a company. For example, the company president might have his own VLAN, his executive
staff might have a different VLAN, and the remaining employees might have yet a different
VLAN. VLANs can also set up according to different company in the same building to save
the money and reduce the device establishment.
This router supports Virtual LAN only in LAN site. User can select some ports to add into a
VLAN group. In one VLAN group, the port number can be single one or more.
The purpose of VLAN is to isolate traffic between different users and it can provide better
security application.
