how to share VLAN between the fortilink interface and regular interface over 40F ?

[shlomim]

Hi,

I have 40F, connected to FortiSwitch 108F.

I'm managing the 108F, and the FortiAPs connected to it via the controller that exist in the 40F.

I've configured the SSIDs to bridge mode, and I want the use the same VLAN for LAN and SSID.

at the moment I've configured under the Fortilink interface, which port a is associated to it an interface VLAN (VLAN 10).

I want VLAN 10 to work over the fortilink and also via port 1

when I connect a second switch (non forti) to port 1 - the port goes up and down (I guess LACP is to blame).

I have the following configuration :
the interface vlan -

config system interface
edit "STAFF"
set vdom "root"
set ip 192.168.10.254 255.255.255.0
set allowaccess ping https ssh http
set device-identification enable
set role lan
set snmp-index 20
set ip-managed-by-fortiipam disable
set switch-controller-igmp-snooping enable
set switch-controller-dhcp-snooping enable
set color 13
set interface "fortilink"
set vlanid 10
next

and then the ssid configuration

config wireless-controller vap
edit "STAFF"
set ssid "STAFF"
set security wpa3-sae-transition
set pmf optional
set mbo enable
set fast-bss-transition enable
set passphrase ENC j/sio2NzB/Z+LA1/dfsK4a8Kt7ToHNzZlQuR9btUkTPcZHjQ5fBRYDAA0wX4zvJxocSETs2ZqktJ5SUytTJajrQetai1epPMYmAPgn1Jay5MFO2XqceLuP5a65/N5OKJHuSYjP+rJe1N75qj2b6pbkpLVDrrL58RgVG96hETumU1EVxr0LxM8dPmrJkeyvgXA2rDXFlmMjY3dkVA
set local-bridging enable
set schedule "always"
set vlanid 10
set multicast-enhance enable
set igmp-snooping enable
set probe-resp-suppression enable
set radio-sensitivity enable
set sae-password ENC RpxH8INav3Kbxkg/AxFS9VcoLulRW9UjknUkrg8fqUSczpZfp1ezuegx3JoHSwWwnkC3m8AminFkA4ALUFU6CZFrkRzvwKfZDx8c51QW6ArwtT6vV53YfzLMKpHyUukijg+joedw96t0u1OhYQGrMMX7hr6TibyC7V4Aji7/Dr8ntaP6+DOioHt3QqRjzoKg3B5QQFlmMjY3dkVA
