VLAN connects devices in different locations together so that they can communicate as if they are on the same LAN. This logical division makes network management more flexible and convenient.

Virtual LAN is implemented through port division and VLAN tagging of switches.

Flexible network management: VLAN can flexibly divide and manage devices as needed, simplifying network configuration and maintenance. Administrators can group devices according to different needs and conduct more granular permission control based on actual conditions.

Improve network performance: By dividing different VLANs, you can reduce the scope of the broadcast domain, avoid broadcast storms and conflicts, and improve the data transmission efficiency and overall performance of the network.

Enhance network security: Through VLAN isolation and permission control, logical isolation between devices in different departments and different security levels can be achieved. This reduces the risk of potential cyberattacks and data breaches.

Improve network reliability: VLAN can achieve network redundancy and link aggregation, improving network reliability and fault tolerance.

Virtual office: According to different departments, different office devices are divided into different VLANs to achieve logical isolation and permission control between offices.

Virtual data center: Divide servers, storage devices and network devices into different VLANs to achieve flexible management of the data center and optimize resource utilization.

Guest network: Provides independent network access services for guests to avoid security threats to the internal network from guest devices.

VoIP network: Divide independent VLANs for VoIP phones, IP cameras and other devices to ensure the quality and security of voice and video transmission.

Internet of Things (IoT): Divide IoT devices into independent VLANs, isolate and manage IoT devices, and ensure network stability and security.
