About Bandwidth Classes

Click to:

Bandwidth classes identify the URL categories and applications to which the service allocates bandwidth.

You must configure the bandwidth classes before you can reference them in Bandwidth Control policy rules.

To configure bandwidth classes, you can edit the predefined bandwidth classes or add new bandwidth classes, then group URL categories, applications, or domains into the bandwidth classes. 

The Cloud Applications tab lists predefined bandwidth classes to which you can add domains. The predefined bandwidth classes cannot be deleted. You can also add your own custom domains.

In this tab, you can also do the following: 

  • Add up to 17 custom bandwidth classes.
