# Managing and Activating Service Sessions

You can use either RADIUS or the CLI to manage, activate, and deactivate service sessions. The following list describes some of the differences between using RADIUS and the CLI to manage the Service Manager application.

- RADIUS-based login and RADIUS CoA support:
  - Provides dynamic activation and deactivation based on subscriber service selection
  - Provides greater flexibility and efficient management for a large number of subscribers and services
  - Enables you to use mutual exclusion (mutex) groups to create mutex services (RADIUS CoA only)
- CLI-based support:
  - Provides static activation and deactivation for subscribers who are always logged in
  - Is useful for testing new service definitions
  - Enables you to preprovision services that you can activate later
