Using Virtual LAN
Setting up Virtual LANs (VLANs) on your PT-7728 increases the efficiency of your network by
dividing the LAN into logical segments, as opposed to physical segments. In general, VLANs are
easier to manage.
The Virtual LAN (VLAN) Concept
What is a VLAN?
A VLAN is a group of devices that can be located anywhere on a network, but which
communicate as if they are on the same physical segment. With VLANs, you can segment your
network without being restricted by physical connections—a limitation of traditional network
design. As an example, with VLANs you can segment your network according to:
y Departmental groups—You could have one VLAN for the marketing department, another
for the finance department, and another for the product development department.
y Hierarchical groups—You could have one VLAN for directors, another for managers, and
another for general staff.
y Usage groups—You could have one VLAN for email users and another for multimedia users.
