D-Link's Adaptable Wireless technology provides you with the choice to associate a wireless network (SSID) with a VLAN
or a tunneled subnet. To associate an SSID with a VLAN, enter a VLAN ID in the VLAN field. To associate an SSID with a
tunneled subnet, enable L3 Tunnel and complete the L3 Tunnel Subnet and L3 Tunnel Mask fields.
The Adaptable Wireless technology offers maximized flexibility. The wireless application can determine how traffic is
handled. For example, guest traffic can be tunneled to the switch for centralized security control, and VoIP traffic can be
tagged with a VLAN ID and forwarded directly from the access point for optimal performance.

Description
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.
Note: When L3 tunneling is enabled the VLAN ID is not used. In
fact, the switch puts the management VLAN ID, if any, on the
tunneled packets.
Note: If the wireless network topology changes (for example, a
DWS-3000 switch reboots) while the L3 tunneling feature is in
use, you should perform an ARP refresh on wired clients to
speed up the process of re-establishing connectivity to the
tunneled network.
Before you enable this feature, make sure your network meets the
design requirements described in
Layer 3 Roaming" on page
For more information about the L3 Roaming network, see
"Configuring a VAP for L3 Tunnels" on page
The default AP profile does not use any security mechanism by
default. In order to protect your network, we strongly recommend
that you select a security mechanism so that unauthorized
wireless clients cannot gain access to your network.
The following WLAN network security options are available:
• None
• WEP
• WPA/WPA2
If you select WEP or WPA/WPA2 as your security mechanism, a
dialogue box asks if you want to change network security. After
you click OK, additional fields appear, and any network settings
that you modified are applied to the switch.
