What is a VLAN (virtual LAN)? A virtual LAN (VLAN) is a logical overlay network that groups together a subset of devices that share a physical LAN, isolating the traffic for each group. A LAN is a group of computers or other devices in the same place -- e.g., the same building or campus -- that share the same physical network.

2023年3月24日 · Virtual LAN (VLAN) is a concept in which we can divide the devices logically on layer 2 (data link layer). Generally, layer 3 devices divide the broadcast domain but the broadcast domain can be divided by switches using the concept of VLAN.

A virtual local area network (VLAN) is any broadcast domain that is partitioned and isolated in a computer network at the data link layer (OSI layer 2). [2][3] In this context, virtual refers to a physical object recreated and altered by additional logic, within the local area network.

2024年11月22日 · VLAN is a custom network which is created from one or more local area networks. It enables a group of devices available in multiple networks to be combined into one logical network. The result becomes a virtual LAN that is administered like a physical LAN.

2022年5月25日 · A virtual local area network is a logical subnetwork of devices in a broadcast domain that is partitioned by network switches and/or network management software to act as its own distinct...

2016年11月23日 · A VLAN is a custom network created from one or more existing LANs. It enables groups of devices from multiple networks (both wired and wireless ) to be combined into a single logical network. The result is a virtual LAN that …

VLANs (Virtual LANs) are logical grouping of devices in the same broadcast domain. VLANs are usually configured on switches by placing some interfaces into one broadcast domain and some interfaces into another. Each VLAN acts as a subgroup of the switch ports in an Ethernet LAN.

2021年6月5日 · A virtual local area network is a logical subnetwork that groups a collection of devices from different physical LANs. Large business computer networks often set up VLANs to re-partition a network for improved traffic management. Several kinds of physical networks support virtual LANs, including Ethernet and Wi-Fi. What Are VLANs Helpful With?

A virtual local area network (VLAN) is a virtualized connection that connects multiple devices and network nodes from different LANs into one logical network. What are the types of VLAN? Virtual local area networks have become crucial for organizations with complex networking systems.

2024年10月14日 · A VLAN is a logical grouping of network resources connected to administratively defined ports on a switch. VLANs break a large broadcast domain into smaller broadcast domains. Each VLAN creates a separate broadcast domain. A LAN is a group of devices connected to a single Ethernet network.
