Once you have defined a Performance Profile, to use it, you must apply it to your system.
You should always apply a Performance Profile at the appliance level. When you do, the profile is inherited for all the other levels. Then, if you have a level that needs a different Performance Profile, you can apply that profile to that level.
Note
The Override settings option is available when you select (highlight) a network level below the appliance level. Use the Expand button to reveal the other levels.
In this example, the PerformanceProfile2 profile will be accessible to corporate-wide employees and guests while the PerformanceProfile1 profile will be available employees and guests on Campus1 of the facilities.
Click the Apply button at the bottom of the screen to save your changes. Click the Reset button to discard your changes.
