Creating VLANs (Virtual Local Area Networks) provides several benefits that help improve the functionality and efficiency of a network. These benefits include:
Segmentation: VLANs help in the segmentation of the network. Segmentation is the process of dividing a network into smaller logical subnetworks, which can help reduce network congestion, improve network performance, and simplify network management. With VLANs, network administrators can group devices that need to communicate with each other into the same VLAN, while keeping them separate from devices that do not need to communicate with them. This can be helpful in environments with large numbers of devices, different security requirements, or different performance needs.
Added Security: VLANs can help improve network security by isolating devices into separate virtual networks, making it more difficult for an attacker to gain access to sensitive data. By configuring VLANs to block or restrict access between VLANs, network administrators can limit the scope of a security breach, and prevent an attacker from accessing other parts of the network. VLANs can also help prevent unauthorized access by restricting access to specific devices or networks, and by providing enhanced authentication and access control mechanisms.
Dedicated Bandwidth: VLANs can provide dedicated bandwidth to specific devices or groups of devices. For example, in a network with multiple VLANs, network administrators can prioritize traffic on certain VLANs, ensuring that critical applications or devices receive the bandwidth they need to function properly. This can help prevent network congestion and ensure that network resources are used efficiently.
Allows switches to route traffic between subinterfaces: VLANs can allow switches to route traffic between subinterfaces, which can help improve network performance by reducing the load on routers. By routing traffic between subinterfaces within the same VLAN, switches can reduce the number of packets that need to be forwarded to a router, resulting in faster response times and improved network performance.
Contains Collisions: VLANs can help contain collisions on a network. When devices on a network share the same physical network segment, collisions can occur, resulting in slower network performance. By separating devices into different VLANs, collisions can be contained within a single VLAN, improving overall network performance.
In conclusion, VLANs provide several benefits that help improve network performance, security, and management. They can help reduce network congestion, improve network performance, and simplify network management by providing logical segmentation. They can also provide enhanced security by isolating devices into separate virtual networks, and provide dedicated bandwidth to specific devices or groups of devices.
