Forward error correction settings on switch ports

Supported managed-switch ports can be configured with a forward error correction (FEC) state of Clause 74 FC-FEC for 25-Gbps ports and Clause 91 RS-FEC for 100-Gbps ports.

config switch-controller managed-switch
    edit <FortiSwitch_serial_number>
        config ports
            edit <port_name>
                set fec-capable {0 | 1}
                set fec-state {disabled | cl74 | cl91}
            next
        end
    next
end

fec-capable {0 | 1}	Set whether the port is FEC capable. 0: The port is not FEC capable. 1: The port is FEC capable.
fec-state {disabled | cl74 | cl91}	Set the FEC state: disabled: Disable FEC on the port. c174: Enable Clause 74 FC-FEC. This option is only available for 25Gbps ports. c191: Enable Clause 91 RS-FEC. This option is only available for 100Gbps ports.

In this example, a FortiSwitch 3032E that is managed by the FortiGate device is configured with Clause 74 FC-FEC on port 16.1 and Clause 91 RS-FEC on port 8.

To configure FEC on the switch ports:

config switch-controller managed-switch
    edit FS3E32T419000000
        config ports
            edit port16.1
                set fec-state cl74
            next
            edit port8
                set fec-state cl91
            next
        end
    next
end
