You can use the following commands to optimize GTP performance:
config system npu
set gtp-support enable
set gtp-enhance-mode enable
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.
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.
