Configuring A Vap For L3 Tunnels; Figure 42: Networks Available To The Wireless Client - D-Link DWS-3000 Series User Manual

Figure 42 shows what a user on a Microsoft Windows XP client sees when the user searches for wireless networks within
range.

Figure 42: Networks Available to the Wireless Client

Although the wireless client finds five different wireless networks, these networks are all on the same access point. The
D-Link Access Point looks like five separate access points to the wireless client.
In this example, the administrator configured multiple VAPs based on different functional groups within the company. Each
VAP has a different SSID, security settings, and VLAN ID to separate traffic.
You can associate the same network (SSID) with multiple VAPs. When you do this, the VAPs look like the same network to
wireless clients. Some administrators configure VAPs with identical settings on each radio so that wireless clients can
connect to the same network whether their wireless adapters are 802.11a or 802.11b/g compatible.
By default, both radios have the same networks assigned to the VAPs, and only VAP0 is enabled. You must configure each
radio independently. In other words, if you enable additional VAPs on one radio, it does not affect the VAPs on the second
radio.

Configuring a VAP for L3 Tunnels

This section provides an overview of the L3 Tunneling feature. For a detailed configuration example of a network that uses
L3 roaming, see Appendix Appendix C:, <Link>"L3 Roaming Example" on page 213.
The L3 Tunnel feature allows mobile stations to maintain their IP connections while roaming from one access point to another
access point even when these access points are attached to different IP subnets. This feature is especially useful for
environments that use wireless Voice over IP (VoIP) on the 802.11 networks with multiple subnets. See "Configuring QoS"
on page 160.
