About SonicOS

This guide is a part of the SonicOS collection of administrative guides that describe how to administer and monitor the SonicWall family of firewalls. SonicOS provides network administrators with the management interface, API (Application Program Interface), and Command Line Interface (CLI) for firewall configuration. You can configure and manage your firewall by setting objects to secure and protect the network services, manage traffic, and provide the desired level of network service. This guide focuses on a way to share SonicWall licenses between two SonicWall firewalls when one is acting as a high-availability system for the other.
