Note that only those VAPs which have non-default configuration are displayed 
when the page initially loads. To configure additional VAPs, click Add Another to 
expose new (empty) VAP entries.

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 
access point look like two or more access point

s

 to other systems on the network. 

By configuring VAPs, you can maintain better control over broadcast and multicast 
traffic that affects network performance. 

You can configure each VAP to use a different VLAN, or you can configure multiple 
VAPs to use the same VLAN. VAP0, which is always enabled, is assigned to 
VLAN 1 by default. VAP1 is also enabled by default and assigned to VLAN 100.

The access point 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 RADIUS servers. One of the servers 
always acts as a primary while the others act as backup servers. The network 
type 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.

The Global RADIUS server settings are collapsed when the page initially loads. To 
show (expand) the Global RADIUS server settings section of the page, click the 
right arrow icon to the left of the Global RADIUS server settings section title. To 
collapse the Global RADIUS server settings section, click the down arrow icon to 
the left of the Global RADIUS server settings section title. 

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 access point assigns the VLAN to all 
wireless clients that connect to the access point through that VAP.

Before you configure VLANs on the access point, be sure to verify that the switch 
and DHCP server the access point uses can support IEEE 802.1Q VLAN 
encapsulation.
