VLANs
This is a status-only window that allows you to review the current status of
configured VLANs. VLANs are virtual LANs used to create broadcast domains.
In addition to listing all VLANs, this window shows your settings for the Default
Route VLAN and the Native (Untagged) VLAN (Step 1 page 202).
Figure 116. VLANs
Understanding Virtual Tunnels
Xirrus Arrays support Layer 2 tunneling. 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. Tunnels may be implemented with:
z
The Xirrus Tunnel Server (XTS)—see the Xirrus Tunnel Server User’s Guide.
z
Virtual Tunnel Server (VTS)—see below.
#
You should create VLAN entries on the Array for all of the VLANs in your
wired network if you wish to make traffic from those VLANs available on the
wireless network. Each tagged VLAN should be associated with a wireless
SSID (see “VLAN Management” on page 201). The Array will discard any
VLAN-tagged packets arriving on its wired ports, unless the same VLAN
has been defined on the Array. See “Undefined VLANs” on page 110.

Xirrus Voice over Wireless Application Note in the Xirrus Resource
