Introduction : Availability of commands and options
 
Availability of commands and options
Some FortiOS™ CLI commands and options are not available on all FortiGate units. The CLI displays an error message if you attempt to enter a command or option that is not available. You can use the question mark ‘?’ to verify the commands and options that are available.
Commands and options may not be available for the following reasons:
FortiGate model. All commands are not available on all FortiGate models. For example, low end FortiGate models do not support the aggregate interface type option of the config system interface command.
Hardware configuration. For example, some AMC module commands are only available when an AMC module is installed.
FortiOS Carrier, FortiGate Voice, FortiWiFi etc. Commands for extended functionality are not available on all FortiGate models. The CLI Reference includes commands only available for FortiWiFi units, FortiOS Carrier, and FortiGate Voice units
