VAP Configuration Overview
The following are required areas of configuration for VAP deployment. This sequence of steps 
is designed specifically to honor dependencies, provide configuration task efficiency, and 
minimize the total number of required steps for VAP configuration.
1.
Zone - The Zone is the backbone of your VAP configuration. Each Zone you create will 
have its own security and access control settings and you can create and apply multiple 
zones to a single physical interface by way of wireless sub-interfaces.
2.
Wireless Subnet - The Wireless subnet represents the IP address segment that will be 
used for the VAP. Each VAP must have its own WLAN subnet, and the WLAN subnet must 
be created before the VAP is created.
3.
NSA DHCP Server - The DHCP server assigns leased IP addresses to users within 
specified ranges, known as “Scopes”. It is important to note here that the default ranges for 
DHCP scopes are often excessive for the needs of most NSA wireless appliance 
deployments. For instance, a scope of 200 addresses for a sub-interface that only supports 
30 users is rather excessive. Be aware of this during your setup and take care to ensure 
the available DHCP lease scope for your NSA is not exhausted.
4.
Virtual Access Points - The Virtual Access Points section allows for setup of general VAP 
settings including SSID, wireless subnet association and authentication settings.
5.
VAP Groups - The VAP Group feature allows for grouping of multiple Virtual Access Points 
into one object to be provisioned to the wireless radio.
6.
Assign WEP Key (optional for WEP encryption) - Up to 4 keys can be defined per-NSA 
wireless appliance, and WEP-enabled VAPs can use these 4 keys independently. WEP 
keys are configured on Wireless > Security page.
7.
Assign Virtual Access Points to Wireless Radio - This feature allows you to choose 
which VAP group to assign to the radio. Only a single VAP Group can be assigned to a 
wireless radio, so ensure that all of the VAPs you wish to make available are assigned to 
this group.
