IPv4 interface-based traffic shaping

NP6, NP6XLite, and NP6Lite offloading of IPv4 interface-based in bandwidth and out bandwidth traffic shaping is supported by some FortiGate models. See this link for a list of supported models and an example configuration.

This feature is supported for physical and LAG interfaces and not for VLAN interfaces. If your FortiGate supports interface-based traffic shaping, you can use the following command to enable this feature:

config system npu

set intf-shaping-offload enable

end

If your FortiGate does not have this command, it does not support NP6, NP6XLite, and NP6Lite offloading of sessions with interface-based traffic shaping.

For FortiGates with NP6, NP6XLite, or NP6Lite processors that do not support offloading of sessions with interface-based traffic shaping, configuring in bandwidth traffic shaping has no effect. Configuring out bandwidth traffic shaping imposes more bandwidth limiting than configured, potentially reducing throughput more than expected.

Once you have enabled support for NP6, NP6XLite, or NP6Lite offloading of interface-based traffic shaping, you can use commands similar to the following to configure interface-based traffic shaping:

config system interface

edit port1

set outbandwidth <value>

set inbandwidth <value>

set ingress-shaping-profile <profile>

set egress-shaping-profile <profile>

end

Enabling NP6, NP6XLite, and NP6Lite offloading of IPv4 interface-based traffic shaping may reduce NP6, NP6XLite, or NP6Lite offloading performance. The performance reduction will depend on your FortiGate configuration and network conditions.
