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.

VLANs partition a single switched network into a set of overlaid virtual networks that can meet different functional and security requirements. This partitioning avoids the need to have multiple, distinct physical networks for different use cases.

2022年5月25日 · What is a VLAN and how does it work? A virtual local area network is a logical subnetwork of devices in a broadcast domain that is partitioned by network switches and/or network...

2021年6月5日 · A VLAN, or virtual area network, is a subnetwork that groups together a collection of devices from different physical LANs. VLANs are often used on business computer networks.

6 天之前 · 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.

In networking, VLANs are implemented and configured on Ethernet Switches and they work at OSI Layer 2. They are a method to logically separate Layer 2 Ethernet Frames generated by different devices in the network so that only frames having the same VLAN ID …

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.

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. The full form of VLAN is defined as Virtual Local Area Network.

VLANs serve two major functions: splitting up one switch into smaller virtual-switches, and extending those virtual-switches to other physical switches.
