Fortiswitch_standalone-to-trunk port cisco

Hi

I have a cisco switch with trunk port connected to a fortswitch in stand alone mode, i am not able to pass the traffic between them, i have this config 

EXAMPLE:

CISCO

inter gi0/1/1

switchport mode trunk

switchport trunk allowed vlan 50,10,100

 

#fortiswitch in standalone

config switch interface

edit port4

set allowed-vlan 50, 10, 100

next

edit port5 

set native vlan 50  (acces port)

next

end

 

i connected a PC to port 5 and i am not able to do ping to gateway. 

 

Some have configured something like that ?? can you share a KB

Hi, thanks for your answer, i already test it in a lab enviroment and it is working fine. I just do something different with the native vlan

What kind of Cisco Switch is it? Some switches default to a non-standard trunking protocol.  Can you enter "Switchport trunk encaps dot1q" on the Cisco interface config?

 

Where is the gateway located? What VLAN is it in?

 

Here's some docs: https://docs.fortinet.com/document/fortiswitch/7.2.3/administration-guide/146335/configuring-vlans

 

Also if you issue command "diagnose switch mac-address list" on the FortiSwitch, do you see any MAC addresses from upstream devices connected to the Cisco switch?

Cheers,
Graham
