Table 12. Wireless Network Configuration
Field Description
VLAN A virtual LAN (VLAN) is a software-based, logical grouping of devices on a
network that allow them to act as if they are connected to a single physical
network, even though they may not be. The nodes in a VLAN share
resources and bandwidth, and are isolated on that network.
The D-Link Unified Access System supports the configuration of a wireless
VLAN. You can configure each VAP to be on a unique VLAN or on the
same VLAN as other VAPs.
When a wireless client connects to the AP by using this network (SSID), the
AP tags the client's traffic with the VLAN ID you configure in this field. By
default, all networks use VLAN 1, which is also untagged by default.
NOTE: The VLAN ID you configure in this field can be overwritten by the
VLAN ID configured for the AP in the RADIUS server. In other words, if
your network uses a RADIUS server to assign wireless clients to VLANs, the
wireless client uses the VLAN ID from the RADIUS server and ignores the
VLAN ID configured on the VAP.
L3 Tunnel 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.
Before you enable this feature, make sure your network meets the design
requirements described in
on page 35.

VAP for L3 Tunnels"
L3 Tunnel Status This field shows the status of L3 Tunneling. In order for tunnel to be
completely configured, routing must be enabled and the switch must have a
routing interface IP address that is in the tunnel subnet. The the status can be
one of the following:
•
•
•
•
L3 Tunnel Subnet The network IP address you enter in this field must be in the same subnet as a
routing interface for the WLAN that you define on the switch.
L3 Tunnel Mask Enter the subnet mask for the network IP address on the L3 Tunnel subnet.
MAC If you enable MAC authentication, wireless clients must be authenticated by
Authentication the AP in order to connect to the network. You must configure the MAC
addresses of the clients to accept or deny (based on the default action you set
in the AP profile) in one of the following databases:
