Chapter 2 Getting Started : Differences between Models : Features
  
Features
There are certain features that are not available on all models. For example, the Switch Controller, which allows a FortiGate unit to manage a FortiSwitch unit, is only available on FortiGate models 100D, 140D, 200D, 240D, 600C, 800C, and 1000C.
Other features may be available only through the CLI on models, while other models have options in the web-based manager. For example, SSL content inspection is a CLI-only feature on FortiGate models 20C, 30C, and 40C, while models 60C+ have options in the web-based manager.
For more information about some of the features that vary by model, please see the Feature/Platform Matrix.
 
If there is a feature you believe your FortiGate model supports that does not appear in the web-based manager as expected, go to System > Config > Features and ensure the feature is turned on. For more information, see “Feature settings”.
