Use the check connectivity status button to trigger a real-time connectivity check against the tunnel to identify whether the tunnel is currently active or idle. Unless you click the on-demand connectivity check button, a check across all tunnels, available across all onboarded devices, occurs once an hour.
CDO runs this connectivity check command on the FTD to determine if a tunnel is active or idle:
show vpn-sessiondb l2l sort ipaddress
Note: Model ASA device(s) tunnels will always show as idle.
