VLANs under fortiswitch

Greeting ,  i've just deployed a new fortiswitch connected via Fortilink to the Fortigate . The Fortigate has already an Avaya switch which need to be replaced by the Fswitch , For test purpose , i gives the VLANs under Fswitch a different IPs range to avoid the duplicate ip , i've created the VLANs and assigned them to the switch ports , Results : All the Native VLANs are working and able to reach the internet , However , The allowed VLANs are not working at all .

I've reconfigured the LLDP profile and setting and assigned it to some ports , doesn't change anything , Here's some config example that i tested on some of the Fswitch ports :

config ports

    edit "port1"

        set poe-capable 1

        set vlan "qtn.FortiSwitch"

        set allowed-vlans-all enable

        set untagged-vlans "vlan.Devices" "vlan.Guest" "vlan.Security"

        set lldp-profile "default"

        set export-to "root"

        set mac-addr *************

    next

    edit "port2"

        set poe-capable 1

        set vlan "vsw.FortiSwitch"

        set allowed-vlans-all enable

        set discard-mode all-tagged--Untagged -- none 

        set lldp-profile "default"

        set export-to "root"

        set mac-addr **************

    next

    edit "port3"

        set poe-capable 1

        set vlan "vsw.FortiSwitch"

        set allowed-vlans "vlan.Servers" "vlan.VoIP"

        set untagged-vlans "qtn.FortiSwitch"

        set export-to "root"

        set mac-addr ******************

        next
