Before configuring your virtual access points, be aware of the following:
Each SonicWall access point must be explicitly enabled for virtual access point support. To verify, navigate to the DEVICE | Access Points > Settings page. Then click the Edit icon for the Access Point Provisioning Profiles > General Settings: Enable option to enable VAP.
Access points must be linked to a WLAN zone on your SonicWall network security appliance to provision the access points.
When using VAPs with VLANs, you must ensure that the physical access point discovery and provisioning packets remain untagged (unless being terminated natively into a VLAN subinterface on the firewall).
You must also ensure that VAP packets that are VLAN tagged by the access point are delivered unaltered (neither un-encapsulated nor double-encapsulated) by any intermediate equipment, such as a VLAN capable switch, on the network.
Be aware that maximum access point restrictions apply and differ based on your SonicWall security appliance.
