Have a FortiGate that is getting slammed with traffic? Tired of not being able to manage the damn thing because of resource utilization? Boy do I have the fix for YOU! Hah, seriously though. If you suffer from these issues then there is definitely a way to guarantee management access to the device as long as you are running FortiOS 5.2 or newer and it is a 2U / blade firewall with mutliple CPUs.

Below are the commands to configure this

conf system npu
set dedicated-management-cpu <enable | disable>
end
