Configuring High Availability Settings

The High Availability feature configures a pair of SonicWALL appliances as a primary and backup. The backup monitors the primary through a series of heartbeats. If the backup detects that the primary is unavailable or has failed, it replaces the primary.

The High Availability feature is available on the following SonicWALL appliances:

•	SonicWALL NSA Series

•	SonicWALL NSA E-Class Series

•	SonicWALL PRO 2040/3060/4060/4100/5060

To configure High Availability settings:

1	Select a SonicWALL appliance and click the Policies tab.

2	Expand the High Availability tree and click Settings. The High Availability page displays.

 

3

Select Enable High Availability. When a SonicWALL appliance becomes active after startup, it looks for an active SonicWALL appliance that is configured for High Availability. If the other appliance is active, it transitions to Idle mode. Sometimes, because of network latency and other issues, it might take a while to find the other SonicWALL appliance.

4	Enter the Serial Number of the Backup SonicWALL security appliance to be used in the High Availability pair.

5	When you are finished, click Update. The settings are changed for each selected SonicWALL appliance. To clear all screen settings and start over, click Reset.
