Справочник Пользователя для SonicWALL 5.8.1

When the WAN Connection Model is set to Ethernet with 3G Failover, the WAN (Ethernet) 
interface is the primary connection. If the WAN interface fails, the SonicWALL appliance fails 
over to the 3G interface.

It is important to note that the WAN-to-3G failover process is different for the three different 
3G Connection Profile dial types: Persistent, Dial on Data, and Manual Dial.

The following sections describe the three different methods of WAN-to-3G failover:
