Splitting the FIM-7941F P19 and P20 interfaces into eight 25G or 10G interfaces

FortiOS 6.4.10 includes the new config system global option qsfpdd-split8-port that you can use to split the P19 or P20 interface of the FIM-7941F into eight 25G interfaces or eight 10G interfaces. For example:

config system global

set split-port 1-P20

set qsfpdd-split8-port 1-P20

end

The FortiGate-7000F reboots and when it starts up, the 1-P20 interface is converted into eight interfaces named 1-P20/1 to 1-P20/8. You must set both split-port and qsfpdd-split8-port.

If you want some or all of these interfaces to operate as 10GigE SR interfaces you can use the config system interface command to change the interface speed. You can change the speed of some or all of the individual split interfaces depending on whether the transceiver installed in the interface slot supports different speeds for the split interfaces.

The qsfpdd-split8-port option is not supported by the FIM-7921F.
