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 VLAN 1.
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 RAIDUS 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.
To set up multiple VAPs, click Manage > VAP.
