According to the FortiManager Administration Guide, provisioning templates are used to configure FortiGate devices in a consistent and efficient way. There are different types of templates, such as system, IPsec, SD-WAN, certificate, and CLI templates. Some characteristics of provisioning templates are:
* You can apply a system template and a CLI template to the same FortiGate device, as long as they do not have conflicting settings1.
* A CLI template can be of type CLI script or Perl script. A CLI script template contains FortiOS CLI commands, while a Perl script template contains Perl code that can generate FortiOS CLI commands2.
* A template group can include a system template and an SD-WAN template, as well as other types of templates. A template group is a collection of templates that can be applied to multiple devices at once3.
* A template group can contain CLI templates of both types, as long as they do not have conflicting settings2.
* Templates are applied in order, from top to bottom. The order of the templates in a template group determines the order in which they are applied to the devices3.
