VLANs enable network segmentation, which enhances performance, security, and manageability. This guide introduces the fundamental concepts of VLANs, their configuration, and how they operate in real-world networking environments. Defining VLANs A VLAN is a logical grouping of devices on a network, allowing them to communicate as though they are on the same physical LAN\u2014even if they are spread across different switches. VLANs provide isolation between different types of traffic, reduce broadcast domains, and allow for..."}
