Using Virtual LAN

Setting up Virtual LANs (VLANs) on your Moxa switch 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. With VLANs you can segment your network according

into:

• Departmental groups—You could have one VLAN for the marketing department, another for the finance

department, and another for the product development department.

• Hierarchical groups—You could have one VLAN for directors, another for managers, and another for

general staff.

• Usage groups—You could have one VLAN for email users and another for multimedia users.
