This is the current status label of the sync FSM for this endpoint, indicating whether the process is running, completed successfully, or has failed. This is the field an admin's monitoring system would poll to alert on a specific VLAN or VSAN endpoint's sync having failed, since it's the top-level pass/fail indicator distinct from the more granular per-stage details above. A status of fail here for a specific endpoint's sync would trigger an admin to dig into the remote error description to find out why that endpoint specifically failed to reconcile between fabrics.
