Resolution

Should an Edge Health Alert event be reported, the following steps are recommended:

1.  Verify that the Edge is correctly configured for its use and function.

• From the Orchestrator UI, navigate to Configure > Edge > Edge Overview. Confirm that the correct profile was assigned to the branch.
• From the GUI navigate to Configure > Edge > Device tab. Review the Edge configurations for each segment.
• Use the SD-WAN Performance and Scale Datasheet  to validate that the model being used is the correct one for the branch.
• From the GUI navigate to Monitor > Edge > System tab. Confirm the amount of tunnels and flows are within the supported values for the platform. Review if there Hand-off Queue drops increased around the time the event was triggered.

2.  Please ensure that the affected Edge is running a recommended  Edge software release. Newer Edge releases will have improvements and optimizations and the issue affecting the Edge may have been resolved in a later release.

3.  If no misconfigurations are found, and there are no scaling issues, please capture a diagnostic bundle and reach out to support via one of the methods found here: https://knowledge.broadcom.com/external/article?legacyId=53907
