Virtual APs
APs advertise WLANs to wireless clients by sending out beacons and probe responses that contain the WLAN’s
SSID and supported authentication and data rates. When a wireless client associates to an AP, it sends traffic to
the AP’s Basic Service Set Identifier (BSSID) which is usually the AP’s MAC address.
In the Dell network, an AP uses a unique BSSID for each WLAN. Thus, a physical AP can support multiple
WLANs. The WLAN configuration applied to a BSSID on an AP is called a virtual AP. You can configure and apply
multiple virtual APs to an AP group or to an individual AP by defining one or more virtual AP profiles.

Virtual AP Configuration Workflow
The following workflow lists the tasks to configure a virtual AP that uses 802.1X authentication. Click any of the
links below for details on the configuration procedures for that task.
Using the WebUI
1. Configure your authentication servers.
2. Create an authentication server group, and assign the authentication servers you configured in step 1 to
that server group.
3. Configure a firewall access policy for a group of users
4. Create a user role, and assign the firewall access policy you created in step 3 to that user role.
5. Create an AAA profile.
a. Assign the user role defined in step 4 to the AAA profile's 802.1X Authentication Default Role
b. Associate the server group you created in step 2 to the AAA profile.
6. Create a new SSID profile
7. Create a new virtual AP profile.
8. Associate the virtual AP profile to the AAA profile you created in Step 5.
9.
Associate the virtual AP profile to the SSID profile you created in Step 6.
