VLANliitäntä

VLANliitäntä refers to a Virtual Local Area Network interface. In computer networking, a VLAN is a way to logically segment a physical network into different broadcast domains. A VLANliitäntä is essentially a virtual port or interface that is assigned to a specific VLAN. This allows network devices to communicate with each other as if they were on the same physical network, even if they are connected to different switches or reside in different physical locations.

The primary purpose of a VLANliitäntä is to enhance network performance, security, and manageability. By segmenting traffic into VLANs, broadcast traffic is confined within each VLAN, reducing the overall network congestion. It also allows for the application of different security policies to different groups of users or devices. For example, a finance department could be on one VLAN, while the IT department is on another, with restricted communication between them. Managing the network becomes simpler as administrators can group devices logically, irrespective of their physical location. Each VLANliitäntä is configured with a specific VLAN ID, which is used by network switches to identify and route traffic belonging to that particular VLAN. This technology is a fundamental component of modern network infrastructure.
