Virtual LANs (VLANs)

Virtual LANs (VLANs) are a logical broadcast domain or logical grouping of interfaces in a local area network (LAN) in which all data received is kept locally and broadcast to all members of the group.

When in Layer 2 mode, VLANs move traffic at wire speed and can span multiple devices. The system supports up to 4093 port-based VLANs and one default VLAN, as specified in IEEE 802.1Q.

VLANs benefits include:
  • Improved security because you can isolate groups of users into different VLANs
  • Ability to create one VLAN across multiple devices
For more information about VLANs, refer to the IEEE Standard 802.1Q Virtual Bridged Local Area Networks. In this guide, also refer to:
