For a service protection class to take effect, it must first be assigned to a virtual server. To do this, click **Services > Virtual Servers** and choose an existing virtual server. Select **Classes** and locate the section entitled “Service Protection”. The Admin UI offers a drop-down box of the service protection classes that are available in the catalog.

After you have selected a service protection class, click **Update**.

The Virtual Traffic Manager applies the new service protection class immediately across all Virtual Traffic Managers. A summary table indicating whether the service protection class is in test or debug mode is shown. If the service protection class has not been enabled (see [Basic Settings](docId:-caWyrmHPZZArLO3dDtOp)) then this is indicated also.
