1) Ensure both FortiGate and FortiSwitch are running on minimum v6.2.0 version, because QSFP phy-mode 6x40G is supported starting v6.2.0 version.
2) If FortiGate and FortiSwitch are running on versions older than v6.2.0 version then go to WiFi & Switch Controller -> Managed FortiSwitch and FortiSwitch ports -> QSFP port 53 and port 54 of FortiSwitch-1048E are not visible.
However, the other QSFP ports 49-52 on FortiSwitch GUI are visible as shown below:
3) Once FortiGate and FortiSwitch-1048E are on v6.2.0 version or higher version, then enable 'phy-mode' port-configuration to '6x40G' on FortiSwitch as shown below:
# config switch phy-mode
set port-configuration 6x40G
set port49-phy-mode single-port
set port50-phy-mode single-port
set port51-phy-mode single-port
set port52-phy-mode single-port
set port53-phy-mode single-port
set port54-phy-mode single-port
end
4) Thereafter, follow the below steps for the new changes to take effect on the FortiSwitch:
- Restart the affected FortiSwitch unit using FortiGate GUI or FortiSwitch CLI command as shown below:
FortiGate GUI:
Got to WiFi & Switch Controller -> Managed Switch, select required FortiSwitch and then select under the drop-down menu hit on 'Restart' button as shown below:
FortiSwitch CLI:
# execute reboot
- Remove/Delete FortiSwitch from being managed on FortiGate:
# config switch-controller managed-switch
delete <FortiSwitch_serial_number>
- Discover the FortiSwitch.
After deleting the Switch from FortiGate, the FortiSwitch automatically re-discovers FortiGate and shows up under WiFi & Switch Controller -> Managed Switch.
- Authorize the FortiSwitch.
Once the FortiSwitch shows up on FortiGate, thereafter authorize the FortiSwitch by navigating to WiFi & Switch Controller -> Managed Switch, select required FortiSwitch and select ‘Authorize’ button on the FortiSwitch as shown below:
- Thereafter, all six QSFP phy-mode 6x40G ports of FortiSwitch-1048E are shown under WiFi & Switch Controller -> FortiSwitch Ports.
