User productivity and adaptability of the network are key drivers for growth and business success. The implementation of VLAN technology allows network supports a more flexible business goals. The main benefits of using VLANs are as follows:

• Security: the groups that have sensitive data separate from the rest of the network, decreasing the chances of occurrence of violations of confidential information.


• Reducing costs: the cost savings resulting from the low need for expensive network upgrades and more efficient use of links and existing bandwidth.


• Best performance: the division of flat Layer 2 network into multiple logical groupings of work (broadcast domains) reduces unnecessary network traffic and power performance.


• Broadcast storms Mitigation: Dividing a network into several VLANs reduces the number of devices that can participate in a broadcast storm. LAN segmentation prevent a broadcast storm spreading across the network.


• Increased IT staff efficiency: VLANs facilitate the management of the network because users with similar requirements for network share the same VLAN. When you provide a new switch, all policies and procedures that are already configured for the particular VLAN are implemented when assigned ports. It is also easy for IT staff to identify the function of providing a VLAN name.


• Application Management or simpler projects: VLANs add users and network devices to support geographic or business requirements. Have separate functions, makes managing a project or work with a specialized application easier, such as a development platform for e-learning for teachers.

The benefits of VLANs are great but they must have extensive knowledge on the subject when you enter the communication between VLANs. This section will explore further in subsequent articles.
