Configuring Security on the WirelessOn D-Link
You configure secure wireless client access by configuring security for each virtual access point (VAP) that you enable. You can configure up to 16 VAPs per radio that simulate multiple APs in one physical access point. By default, only one VAP is enabled. For each VAP, you can configure a unique security mode to control wireless client access.Each radio has 16 VAPs, with VAP IDs from 0-15. By default, only VAP 0 on each radio is enabled. VAP0 has the following default settings:
•) VLAN ID: 1
•) Broadcast SSID: Enabled
•) SSID: dlink1
•) Security: None
•) MAC Authentication Type: None
•) Redirect Mode: None
All other VAPs are disabled by default. The default SSID for VAPs 1–15 is ”dlinkx” where x is the VAP ID.To prevent nauthorized access to the UAP, we recommend that you select and configure a security option other than None for the default VAP and for each VAP that you enable.
To change VAP 0 or to enable and configure additional VAPs, select the VAP tab in the Manage section.VAPs segment the wireless LAN into multiple broadcast domains that are the wireless equivalent of Ethernet VLANs.VAPs simulate multiple APs in one physical AP. Each radio supports up to 16 VAPs.
For each VAP, you can customize the security mode to control wireless client access. Each VAP can also have a unique SSID. Multiple SSIDs make a single AP look like two or more APs to other systems on the network.By configuring VAPs, you can maintain better control over broadcast and multicast traffic, which affects network performance.
You can configure each VAP to use a different VLAN, or you can configure multiple VAPs to use the same VLAN,whether the VLAN is on the same radio or on a different radio. VAP0, which is always enabled on both radios, is assigned to the default VLAN1.
The AP adds VLAN ID tags to wireless client traffic based on the VLAN ID you configure on the VAP page or by using the RADIUS server assignment. If you use an external RADIUS server, you can configure multiple VLANs on each VAP. The external RADIUS server assigns wireless clients to the VLAN when the clients associate and authenticate.
You can configure up to four global IPv4 or IPv6 RADIUS servers. One of the servers always acts as a primary while the others act as backup servers. The network type (IPv4 or IPv6) and accounting mode are common across all configured RADIUS servers. You can configure each VAP to use the global RADIUS server settings, which is the default, or you can configure a per-VAP RADIUS server set. You can also configure separate RADIUS server settings for each VAP. For example, you can configure one VAP to use an IPv6 RADIUS server while other VAPs use the global IPv4 RADIUS server settings you configure.
If wireless clients use a security mode that does not communicate with the RADIUS server, or if the RADIUS server does not provide the VLAN information, you can assign a VLAN ID to each VAP. The AP assigns the VLAN to all wireless clients that connect to the AP through that VAP.
Note: Before you configure VLANs on the AP, be sure to verify that the switch and DHCP server the AP uses can support IEEE 802.1Q VLAN encapsulation.
