Initial High Availability Setup

Before you begin the configuration of HA on the Primary
Dell SonicWALL security appliance, perform the following
tasks:
• Determine which interfaces should be used as the HA Control
Link and the HA Data Link. Remember, they must be the
same ports on each appliance.
• On the bottom panel of the appliance that will run as the
Secondary device, locate the serial number and write the
number down. You need to enter this number in the High
Availability > Settings > HA Devices page.
• Verify that the Primary and Secondary appliances are
registered on MySonicWALL, running the same SonicOS
versions.

Configuring High Availability Settings

The first task in setting up HA after completing the
section, on page 14 is configuring the High Availability >
Settings page on the Primary Dell SonicWALL security
appliance. Once you configure HA on the Primary appliance, it
communicates the settings to the Secondary appliance.
To configure HA on the Primary Dell SonicWALL, log in to your
Primary appliance and perform the following steps:
1. Navigate to the High Availability > Settings page.
2. On the General tab, select Active / Idle from the Mode
dropdown menu.
3. Select the Enable Stateful Synchronization checkbox.
4. Next, navigate to the HA Devices tab and type in the serial
number for the Secondary appliance.
5. Navigate to the HA Interfaces tab and specify an HA
Control Interface and an HA Data Interface.
6. Click Apply to save these settings. All settings will be
synchronized to the Secondary appliance, and the
Secondary appliance will reboot.
