Virtual LANs, or VLANs, are a logical broadcast domain or logical grouping of interfaces in a 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. FTOS supports up to 4093 port-based
VLANs and 1 Default VLAN, as specified in IEEE 802.1Q.
VLANs provide the following benefits:
• Improved security because you can isolate groups of users into different VLANs
• Ability to create one VLAN across multiple devices
For more information on VLANs, refer to IEEE Standard 802.1Q Virtual Bridged Local Area Networks.
