Virtual LANs (VLANs) are a way to segment a network into multiple logical networks. This can be useful for isolating different types of traffic, such as voice and data traffic, or for creating separate networks for different departments or workgroups. VLANs can be created and managed using a variety of methods, including through a network switch or router.
There are several ways to check the VLAN configuration on a network switch or router. One common method is to use the command-line interface (CLI) of the device. Another method is to use a network management system (NMS), which can provide a graphical user interface (GUI) for managing VLANs.
