Benefits of VLAN

VLAN is a network structure which allows users to communicate while in different locations by sharing one multicast domain and a single broadcast. They provide numerous networking benefits and have become popular in the market. For instance, it helps reduce administrative costs when users are geographically dispersed.

1. Inexpensive

The popularity of VLANs is due to the fact that changes, adds, and moves can be attained simply by making necessary configurations on the VLAN port. Time-consuming, re-addressing, and host reconfigurations is now a thing of the past, because network configuration can be made at ease when need arises.

2. Better management

A VLAN typically solve the scalability issues that exist in a large network by breaking the main domain into several VLAN groups or smaller broadcast configurations, thereby encourage better control of multicast traffic as well as broadcast domains.

3. Improves network security

High-security can be positioned in different VLAN groups to ensure that non-members cannot receive their broadcasts. On the other hand, a router is added and workgroups relocated into centralized locations.

4. Enhances performance

VLAN groups are often defined on vast criteria, making it is easy to evaluate traffic patterns on the network and associate resources and users logically. For instance, an engineer working on CAD/CAM network server can be placed into a different VLAN group that contains just the server and the engineer. The engineer performance increases without affecting other servers.

5. Segment multiple networks

VLANs are typically used to achieve multiple purposes. They are popularly used to reduce multicast traffic. Since certain devices send out massive amounts of traffic during broadcasting, VLANs help in limiting network traffic.

6. Better administration

VLANs facilitate grouping of multiple geographical stations. When VLAN users move to another physical location, the network does not have to be configured.

It may be difficult to manage several routing protocols on VLAN since you have to use a router, a trunk and routing protocol.
