This feature enables more flexible and efficient SD-WAN deployments by allowing you to customize device capacity settings. By adjusting the balance between SD-WAN rules, interfaces, and members, you can scale your network to support up to 16 members per VIF while maintaining optimal system performance.

To ensure uninterrupted connectivity between the SD-WAN devices and Panorama, the SD-WAN plugin introduces an option to configure the dedicated tunnel to Panorama. Unlike the SD-WAN overlay network connectivity to Panorama that may go down, which causes unreachability of SD-WAN devices to Panorama, the dedicated tunnel stays connected all the time.

The dedicated tunnel to Panorama establishes a persistent and dedicated IPSec tunnels from your branch devices to Panorama through designated termination devices using direct internet access (DIA) interfaces. With dedicated tunnels in place, even if your primary SD-WAN overlay network becomes unavailable, your devices can still reach Panorama to receive configuration updates and troubleshooting commands.
