Check Site-to-Site VPN Tunnel Connectivity

Use the Check Connectivity 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.

Note
  • CDO runs this connectivity check command on the ASAFTD to determine if a tunnel is active or idle: 
    show vpn-sessiondb l2l sort ipaddress

  • Model ASA device(s) tunnels will always show as Idle.

To check tunnel connectivity from the VPN page:
