Table 14: Wireless Network Configuration

Field Description

SSID Wireless clients identify a wireless network by the SSID, which is an alphanumeric key that

uniquely identifies a wireless local area network. The SSID can be up to thirty-two characters

in length, and there are no restrictions on the characters that may be used in an SSID.

Hide SSID You can hide the SSID broadcast to discourage stations from automatically discovering your

access point. When the broadcast SSID of the AP is hidden, the network name is not

displayed in the list of available networks on a client station. Instead, the client must have the

exact network name configured in the supplicant before it is able to connect.

Disabling the broadcast SSID is sufficient to prevent clients from accidentally connecting to

your network, but it will not prevent even the simplest of attempts by a hacker to connect, or

monitor unencrypted traffic.

This offers a very minimal level of protection on an otherwise exposed network (such as a

guest network) where the priority is making it easy for clients to get a connection and where

no sensitive information is available.

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.

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 “Network Planning to Support Layer 3 Roaming” on page 37.

For more information about the L3 Roaming network, see “Configuring a VAP for L3 Tunnels”

on page 95.

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 status can be one of the following:

• None (L3 Tunnel is disabled or the network is not associated with any AP profiles)

• Configured

• Not Configured - Routing Disabled

• Not Configured - No Routing Interface

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.
