   |   Configuring a Stateful HA Pair  

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.

• Ensure the Primary and Secondary security appliances’ LAN, 

WAN, and other interfaces are properly connected for failover.

• Connect the HA Control and Data Links on the Primary and 

Secondary appliances with appropriate cables. 

• Turn on the Primary Dell SonicWALL security appliance first. 

Then, turn on the Secondary Dell SonicWALL security 
appliance.

The first task in setting up HA after completing 

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.
