Optimizing 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 these commands you should restart your FortiGate-7000E 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-7000E to initialize the changes.

You can also use the following command to select the CPUs that can perform GTP-U packet inspection.

config system npu

set gtp-enhance-cpu-range {0 | 1 | 2}

end

Where:

0 all CPUs will process GTP-U packets

1 only primary CPUs will process GTP-U packets.

2 only secondary CPUs will process GTP-U packets.
