This can save bandwidth for other applications and ensure VoIP quality. If your organization uses voice over IP (VoIP), you will really need a separate voice VLAN. Before you jump right into configuring your data VLANs, take a look at the entire landscape of possible VLANs, and take the time to assess the logic of how to best segment your users.
How you group your data VLANs (such as by department or workgroup, for example) will depend on your organizational structure and business processes. In addition to the security benefits, it ensures that bandwidth for management will be available even when the user is experiencing high traffic.Īlso known as user VLANs, data VLANs are intended for user-generated data only. Types of VLANsīest practice is to set up separate VLANs for management traffic such as monitoring, system logging, SNMP, and other potentially sensitive management tasks. An example of such an application is an e-learning development platform for universities. VLANs have separate functions, making it easier to manage a project or work with a specific application. Simple project and application management IT staff can more freely have other time that can be used to organize various other work. IT staff efficiency improvementįor IT staff, of course, VLANs are able to give them more free time than having to always monitor traffic from the traffic of a network topology that they monitor. Limiting broadcast domains on the network can significantly reduce traffic. Packet flooding is limited to the switch ports belonging to the VLAN.
VLANs reduce the need to have routers placed on the network to accommodate broadcast traffic. If a device in one VLAN sends an ethernet broadcast frame, all devices in the VLAN receive the frame, but devices in the other VLAN do not. This is why VLANs can improve network performance by separating large broadcast domains into smaller ones. VLANs provide a way to group devices within a LAN. VLANs will work well for small businesses, especially for businesses that are looking to expand their network size for future growth. One of the advantages of VLANs is that multiple bridge domains can be shared logically on a single switch platform. When devices are separated into multiple VLANs it is easier to prevent compromised computers from infecting the entire network. In addition, VLANs can also provide additional security. Among others are: SecurityĬompared to LANs, VLANs have the advantage of reducing network traffic and collisions, as well as being more cost-effective. Of course there are various functions followed also benefits which are very important for the traffic of a network topology. VLAN Functions and BenefitsĪfter understanding how VLANs work, then of course you will wonder what the functions and benefits of VLANs are specifically. On a common or unmanageable switch, the port can only be used for connections between networks and does not support the VLAN feature.
