1. Improved Network Performance and Security: VLANs allow networks to be divided into multiple broadcast domains, which can help reduce network congestion and improve the overall performance of the network. VLANs also help to provide security by isolating traffic, as each VLAN is a separate broadcast domain.
2. Reduced Costs: By using VLANs, network administrators can reduce the cost of network devices, as they are able to use fewer switches and routers to connect multiple devices on a single network.
3. Simplified Troubleshooting: VLANs help to simplify troubleshooting by allowing network administrators to easily identify the source of a problem.
4. Increased Scalability: VLANs allow for networks to be easily scaled up or down, as they are not bound to physical locations. This allows for increased flexibility when adding or removing devices from the network.
5. Quality of Service (QoS): VLANs can be used to provide quality of service (QoS) to certain types of traffic, allowing for improved performance for certain applications, such as VoIP or streaming multimedia.
1. Improved Security: VLANs allow administrators to segment networks, limiting the potential attack surface of each segment. VLANs segregate traffic from different groups without the need for physical separation, providing a layer of isolated, secure communication.
2. Enhanced Performance: Traffic is directed only to intended users or resources, which improves overall network performance by eliminating any unnecessary traffic.
3. Improved Scalability: As companies grow and their networks expand, VLANs make expanding networks much simpler by allowing new devices, hosts, and users to be added with minimal reconfiguration.
4. Cost Savings: VLANs reduce infrastructure costs as they can be used to interconnect geographically dispersed areas and eliminate the need for point–to–point wiring.
5. Reduced Broadcast Traffic: By breaking up broadcast domains into smaller ones based on certain criteria, VLANs help limit the effect of broadcast storms in a network. This allows for higher performance with less overhead.
