Description
This article provides the information of FortiLink auto-discovery feature which is an automatic detection of the port connected to the FortiGate.

Scope
From version 3.3.0 to 6.4.

Solution
The D-series FortiSwitch models support FortiLink auto-discovery feature.
Any of the Switchports can be used for FortiLink. Use the following FortiSwitch CLI commands to configure a port for FortiLink auto-discovery:
# config switch interface
    edit <port>
        set auto-discovery-fortilink enable
    next
end
Note.
By default some FortiSwitch ports are enabled for auto-discovery.

Example.
By default each FortiSwitch have a set of ports that are enabled for FortiLink auto-discovery.
If the FortiLink using one of these ports is connected, no FortiSwitch configuration is required.


From the FortiSwitchOS 3.4.0 and later, the last four ports are set as auto-discovery FortiLink ports.

Below list provides the default auto-discovery ports for each FortiSwitch model:

FS-108D -> ports 9 and 10.
FSR-112D  -> ports 9, 10, 11, and 12.
FS-124D, FS-124D-POE -> ports 23, 24, 25, and 26.
FS-224D-POE  -> ports 21, 22, 23, and 24.
FS-224D-FPOE ->  ports 25, 26, 27, and 28.

FS-248D-POE -> ports 49, 50, 51, and 52.
FS-248D-FPOE -> ports 49, 50, 51, and 52.
FS-424D, FS-424D-POE, FS-424D-FPOE -> ports 25 and 26.
FS-448D, FS-448D-POE, FS-448D-FPOE -> ports 49, 50, 51, and 52.
FS-524D, FS-524D-FPOE  -> ports 25, 26, 27, 28, 29, and 30.
FS-548D, FS-548D-FPOE -> ports 49, 50, 51, 52, 53, and 54.
FS-1024D, FS-1048D, FS-3032D ->  all ports.

Also, the below command can be used to see the ports that have auto-discovery enabled on Fortiswitch:
