FortiOS Carrier

Improving NP6 GTP performance

Some FortiGate models with NP6 processors support improving FortiOS GTP performance by enabling the following option:

config system npu

set gtp-enhance-mode enable

end

This feature is available for the following FortiGate models:

  • FortiGate-3700D, 3800D, 3400E, 3401E, 3600E, and 3601E
  • All FortiGate-7000 models

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 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 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.
