VLANs under fortiswitch

[kronos]

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
