max-receive-unit <size>

You can use the following command to set the maximum packet size in bytes allowed by NP7 processors. Larger packets will be silently dropped.

config system npu

set max-receive-unit <size>

end

You can set the packet size from 64 bytes to 10,000 bytes. The default is 10,000 bytes.

If you change the config system npu option default-qos-type to shaping, Fortinet recommends setting max-receive-unit to 6000.
