VLAN

This feature may not be available on all platforms. Please check your system's actual page if your device delivers this feature.

VLAN, the abbreviation for Virtual Local Area Network, is defined in IEEE 802.1Q. VLAN has the following features:

  • A physical LAN can be divided into multiple VLANs, and a VLAN might include devices from multiple physical networks.

  • A VLAN is virtually a broadcast domain. Layer 2 packets between VLANs are isolated. Communication between VLANs can only be implemented by a Layer 3 route technique (through routers, Layer 3 switches, or other Layer 3 network devices).

VLANs are distinguished by VLAN numbers. The value range is 1 to 4094. System reserves 32 VLAN numbers (224 to 255) for BGroup, but the unused numbers within the range are also available to VLANs.
