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
