Primary Connections

Primary internet interfaces are utilized for all traffic under normal operating conditions. Typically the most reliable and unlimited internet sources are set to Primary, such as fiber, cable, unlimited 4G or 5G, or satellite. Multiple interfaces configured as Primary share traffic load according to capacity and quality metrics.

Failover role: Remains active during all operational states.

Secondary Connections

Secondary network interfaces activate when aggregate demand exceeds Primary interface capacity. Typically used for more expensive or less reliable connections, such as 4G or 5G cellular, expensive satellite internet, or a secondary broadband source, as a supplement for the Primary connections. Acts as overflow capacity rather than constant participant.

Failover role: Automatically promoted to active status if Primary interfaces fail, regardless of current traffic load.

Cost optimization: Minimizes data consumption on expensive interfaces while maintaining them as available capacity. Particularly relevant for cellular connections with tiered pricing above quota thresholds.

Backup Connections

Backup internet connections remain inactive unless all Primary and Secondary interfaces become unavailable. Typically reserved for the most limited, expensive internet sources. Provides connection continuity during infrastructure failures.

Failover role: Last-resort connectivity. Automatically deactivates when higher-priority interfaces restore.

Cost control: Prevents inadvertent consumption of expensive backup capacity during normal operations.

Never to Be Used Connections

Never priority is for network interfaces detected by the system but explicitly excluded from all traffic routing. Functionally equivalent to disabling the interface for Speedify usage.

Management: Interface remains visible in configuration but excluded from operational display. Can be re-enabled by changing priority level.
