Description This article describes a known issue where SD-WAN logs display the parent tunnel interface instead of the shortcut tunnel interface in specific health-check events.
Scope FortiGate v7.2.8
Solution

When the health check of a shortcut tunnel interface fails, the following logs are observed in the SD-WAN Events:

However, the logs that follow show the parent tunnel interface, 'iNet_B_H', instead of the shortcut tunnel interface 'iNet_B_H_0':
