Configuring the Wi-Fi Array 203
VLANs
This is a status only window that allows you to review the current status of
assigned VLANs. A VLAN (Virtual LAN) is comprised of a group of devices that
communicate as a single network, even though they are physically located on
different LAN segments. Because VLANs are based on logical rather than
physical connections, they are extremely flexible. A device that is moved to
another location can remain on the same VLAN without any hardware
reconfiguration.
In addition to listing all VLANs, this window shows your settings for the Default
Route VLAN and the Native (Untagged) VLAN (Step 1 page 205).

Understanding Virtual Tunnels
Xirrus Arrays support Layer 2 tunneling with Virtual Tunnels. This allows an
Array to use tunnels to transport traffic for one or more SSID-VLAN pairs onto a
single destination network through the Layer 3 core network.
The Array has low overhead and latency for VTun connections, with high
resilience. The Array performs all encryption and decryption in hardware,
maintaining wire-rate encryption performance on the tunnel.
