Defining SSID Groups
Optionally, you can define SSID Groups. An SSID Group has SSIDs as members and can be specified just like an SSID in a FortiAP Profile.
To create an SSID Group - GUI
Go to WiFi & Switch Controller > SSID and select Create New > SSID Group. Give the group a Name and choose Members (SSIDs, but not SSID Groups).
To create an SSID Group - CLI:
config wireless-controller vap-group
set vaps "ssid1" "ssid2"
