  ,D - When "Prefer Passive" is set, FortiGate attempts to passively monitor the health of SD-WAN members using real application traffic like TCP sessions, collecting statistics such as latency, jitter, and packet loss from actual observed flows. Passive monitoring does not generate probe packets; it relies entirely on existing traffic. If there is no matching traffic, health check data is unavailable, meaning dead members may go undetected when only passive monitoring is active.
