Prerequisites for WLANs
You can associate up to 16 WLANs with each access
point group and assign specific access points to
each group. Each access point advertises only the
enabled WLANs that belong to its access point
group. The access point (AP) does not advertise
disabled WLANs in its access point group or WLANs
that belong to another group.
We recommend that you assign one set of VLANs for WLANs and a different set of VLANs for management interfaces to ensure that controllers properly route VLAN traffic.
The controller uses different attributes to differentiate between WLANs with the same Service Set Identifier (SSID).
WLANs with the same SSID and same Layer 2 policy cannot be created if the WLAN ID is lower than 17.
Two WLANs with IDs that are greater than 17 and that have the same SSID and same Layer 2 policy is allowed if WLANs are added in different AP groups.
This requirement ensures that clients never detect the SSID present on the same access point radio.
Information About AAA Override
The AAA Override option of a WLAN enables you to configure the WLAN for identity networking. It enables you to apply VLAN tagging, Quality of Service (QoS), and Access Control Lists (ACLs) to individual clients based on the returned RADIUS attributes from the AAA server.
