What is the maximum number of backup interfaces that can be configured for SDWAN?

The maximum number of backup interfaces that can be configured for SDWAN is 10. This configuration allows for redundancy and failover capabilities, ensuring that if a primary interface experiences issues or fails, there are sufficient additional interfaces available to maintain connectivity and performance. This is crucial for businesses that rely on consistent and reliable network connections.

In SDWAN environments, having multiple backup interfaces helps improve network resilience and performance by distributing the traffic more effectively across available resources, which can also improve overall user experience.

The configurations and limits set by SonicWall are designed to enhance operational effectiveness while keeping in mind the complexity that larger numbers of interfaces could introduce. Thus, 10 is a balanced and practical limit for backup interfaces in an SDWAN scenario.
