Software User Manual 12/10/09 D-Link Unified Access System SSID CONFIGURATION The SSID tab displays the virtual access point (VAP) settings associated with the default AP profile. Each VAP has an associated network, which is identified by its network number and Service Set Identifier (SSID). You can configure and enable up to 16 VAPs per radio on each physical access point. Figure 295: VAP Settings VAPs segment the wireless LAN into multiple broadcast domains that are the wireless equivalent of Ethernet VLANs. To a wireless client, each VAP appears to be a single physical access point. However, since the VAPs use the same channel, there is no risk of RF interference among the networks that are on a single AP. VAPs can help you maintain better control over broadcast and multicast traffic, which affects network performance. You can also configure different security mechanisms for each VAP. A VAP is a physical entity. Each VAP maps directly to a MAC address. A network is a logical entity that you apply to a VAP. Networks are identified by a network number and an associated SSID. The SSID does not need to be unique for each network. You can create and modify a network in one place and apply the network to one or more VAP as needed. This allows you to mix networks within different profiles without having to reconfigure everything. When you edit a network configuration that is applied to more than one VAP, you edit it for every VAP that uses the network. Managing Virtual Access Point Configuration The Default AP profile has one VAP on each radio enabled by default. The default VAP uses the dlink1 SSID, and there is no security to prevent wireless clients from associating with the VAP. To enable additional VAPs, select the check box next to the VAP. Once you enable a VAP, you can select the network (SSID) to use from the drop-down menu. To change Network settings, click Edit. Table 262 describes the fields on the SSID page. Field Radio 1 Radio 2 Table 262: Default VAP Configuration Description You configure the VAPs for Radio 1 and Radio 2 separately. Select the radio to configure the settings for before you enable the VAP. Document 34CSFP6XXUWS-SWUM100-D7 Basic Setup Page 423
