Virtual Local Area Networks (VLANs) have become a popular network solution in recent times. They enable administrators to break up huge networks in smaller, easier to manage subnetworks, thereby enhancing security along with flexibility, scalability, and flexibility. The article below we’ll examine what VLANs are, why you should make use of them and how they function.
What is a VLAN?
An VLAN is a rational grouping of devices in an internet network regardless of physical place of residence. Devices that are on the same VLAN are able to communicate with each others as if in the exact same network even if they’re on subnets or switches that are different. VLANs are usually created with switches and are usually built around criteria such as department of function, area, or.
Why use a VLAN?
There are many reasons you may need to utilize VLANs:
Improved Security
When you separate devices into different VLANs You can restrict the amount of information that can be seen by every device. This can stop unauthorized access and lower the possibility of attacks like malware-related infections and network security breaches.
Better Performance
By dividing a system into smaller VLANs and reducing the volume of broadcast traffic and congestion within the network, which leads to better performance and less collisions.
Simplified Network Management
VLANs make managing your network easy, since they permit you to rationally group devices and run them as one entity. This can simplify your network, and help you troubleshoot issues.
How do VLANs function?
VLANs operate through assigning computers to groups according to the criteria of function, department or even locations. The groups are then separated from one another, meaning that devices in one VLAN cannot connect to devices that are on a different VLAN without using the router or another Layer 3 devices.
For assigning devices to VLANs you can employ various methods that include port-based VLANs or MAC-based or VLANs based on protocols. Port-based VLANs are the most popular method, in which each port of a switch is assigned one particular VLAN.
Conclusion
VLANs are a very effective networking device that offers enhanced security, performance, and management of your network. By dividing your networks into smaller easier to manage subnetworks, it is possible to simplify management of your network as well as reduce the possibility of attack, and boost efficiency of the entire network.
