8 SETTING UP VIRTUAL LANS Setting up Virtual LANs (VLANs) on your Switch reduces the time and effort required by many network administration tasks, and increases the efficiency of your network. This chapter explains more about the concept of VLANs and explains how they can be implemented on your Switch. It covers the following topics: ■ What are VLANs? ■ Benefits of VLANs ■ VLANs and Your Switch ■ VLAN Configuration Examples For detailed descriptions of the web interface operations and the command line interface (CLI) commands that you require to manage the Switch please refer to the Management Interface Reference Guide supplied in HTML format on the CD-ROM that accompanies your Switch. What are VLANs? A VLAN is a flexible group of devices that can be located anywhere in 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: ■ Departmental groups - For example, you can have one VLAN for the Marketing department, another for the Finance department, and another for the Development department. ■ Hierarchical groups - For example, you can have one VLAN for directors, another for managers, and another for general staff. ■ Usage groups - For example, you can have one VLAN for users of e-mail, and another for users of multimedia.
