Fortilink DHCP

Hi,
I have a question about the fortilink. I transformed port A of my fortinet into a classic lan port.
And I use a DHCP on this port but it does not work, I do not get any ip address (if I fix the IP address, the network works)
the DHCP does not work because it is a Fortilink port? How can I solve this problem?

I would check the interface settings and remove it's role as a FortiLink:

 

conf sys int
   edit "a"
      set fortilink disable
   next
end

Then, I'd check if the DHCP server is restricted to only serve certain devices identified by a VCI string:

config system dhcp server
    edit 4
        set default-gateway 169.254.2.1
        set netmask 255.255.255.0
        set interface "port18"
        ...
        set vci-match enable
        set vci-string "FortiSwitch" "FortiExtender"
    next

If so, just set "set vci-match disable" to fix.

It should work no problem. FortiLink uses DHCP to provide addressing to switches and aps.

 

Do you have DHCP running on other interfaces OK?

 

Do other devices on port A suffer the same issue of not getting DHCP or is it just this one device?

 

What do your log messages show or packet captures show for the DHCP process?

Cheers,
Graham
