Hardware Acceleration

Disabling NP6, NP6XLite, and NP6Lite hardware acceleration (fastpath)

You can use the following command to disable NP6 offloading for all traffic. This option disables NP6 offloading for all traffic for all NP6 processors.

config system npu

set fastpath disable

end

fastpath is enabled by default.

This command is also available on some FortiGate models that include NP6Lite processors depending on the firmware version.

FortiGate models with NP6XLite processors

FortiGate models with NP6XLite processors include the following command to disable NP6XLite offloading:

config system np6xlite

edit np6xlite_0

set fastpath disable

end

fastpath is enabled by default. This command disables offloading for individual NP6XLite processors, in the example, np6xlite_0.

Using a diagnose command to disable hardware acceleration

Most FortiGate models and firmware versions include the following diagnose command to disable or enable hardware acceleration.

diagnose npu <processor-name> fastpath disable <id>

processor-name can be np6, np6xlite, or np6lite.

fastpath is enabled by default.

id specify the ID of the NP6, NP6XLite, or NP6Lite processor for which to disable offloading.

If you use this command to disable hardware acceleration, when your FortiGate restarts, fastpath will be enabled again since diagnose command changes are not saved to the FortiGate configuration database. This may be the only option for disabling hardware acceleration for some FortiGate models and some firmware versions.

If you use this command to disable hardware acceleration, when your FortiGate restarts, fastpath will be enabled again since diagnose command changes are not saved to the FortiGate configuration database.
