Configuring HA Settings

After disabling PortShield on all interfaces of both appliances,

Availability > Settings page on the Primary SonicWALL
security appliance. Once you configure HA on the Primary, it
communicates the settings to the Backup SonicWALL security
appliance.
To configure HA on the Primary SonicWALL, perform the
following steps:
1. Navigate to the High Availability > Settings page.
2. Select the Enable High Availability checkbox.
3. Under SonicWALL Address Settings, type in the serial
number for the Backup SonicWALL appliance.
You can find the serial number on the back of the
SonicWALL security appliance, or in the System > Status
screen of the backup unit. The serial number for the
Primary SonicWALL is automatically populated.
4. Click Apply to retain these settings.

Configuring Advanced HA Settings

1. Navigate to the High Availability > Advanced page.
2. To configure the HA Pair so that the Primary SonicWALL
resumes the Active role when coming back online after a
failover, select Enable Preempt Mode.
3. To backup the settings when you upgrade the firmware
version, select Generate/Overwrite Backup Firmware
and Settings When Upgrading Firmware.
