I created a interface group on my WLC which contains two dynamic interfaces.
My interface group is assigned to WLAN.
My problem is clients gets IP address of my native vlan id (Flex Connect)
When I go to my AP tab Flex Connect and check the vlan mappings it maps the SSID to my native vlan.
When I map a WLAN to interface only it works and shows the correct vlan mappings with SSID on vlan mapping tab under Flex Connect.
