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.

Notes: 

  • CDO runs this connectivity check command on the ASA and FTD 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:

  1. From the main navigation bar, click VPN > Site-to-Site VPN.  
  2. Search and filter the list of tunnels for your site-to-site VPN tunnel and select it. 
  3. In the Actions pane at the right, click Check Connectivity.

You can also check tunnel connectivity in the Tunnel Details table:

  1. From the main navigation bar, search and filter for the device you want to check VPN site-site-connectivity.
  2. In the Management pane, click VPN.
  3. Double-click the other end of the VPN tunnel.
  4. Click the Tunnel Details tab. 
  5. Click the Check Connectivity button recycle_button.png for the tunnel
