Optimizing FortiOS Carrier NPU GTP performance

You can use the following commands to optimize GTP performance:

config system npu

set gtp-support enable

set gtp-enhance-mode enable

end

There are independent Receive and Transmit queues for GTP-U processes. These queues and their associated resources are initialized when gtp-enhance-mode is enabled. After entering this command, you should restart your FortiGate 7000F to initialize the changes.

If you restore a configuration file, and if that restored configuration file has a different gtp-enhance-mode setting you should restart your FortiGate 7000F to initialize the changes.

To enable gtp-enhance-mode for an operating FortiGate 7000F FGCP HA cluster, you need to remove the backup FortiGate 7000F from the cluster, enable gtp-enhance-mode for both FortiGate 7000Fs, restart both FortiGate 7000Fs, and then re-form the cluster. This process will cause traffic interruptions.
