Monitor AWS VPC Tunnels using AWS Transit Gateway

Amazon Web Service (AWS) Transit Gateway acts as a cloud router connecting enterprise virtual private clouds (VPCs) to AWS VPCs through a central hub that allows for simplified peering relationships.

Cisco Defense Orchestrator (CDO) allows you to monitor the connection status of your onboarded AWS VPCs using AWS Transit Gateway.


Step 1

In the CDO menu bar, select VPN > Site-to-Site VPN.

Step 2

The VPN Tunnels page displays the connection status for all network tunnels managed by your CDO tenant. The connection status for the VPN tunnel can be active or idle.

Step 3

Select a VPC and under Actions click Check Connectivity to trigger a real-time connectivity check against the tunnel and identify whether the tunnel is currently active or idle. Unless you click the on-demand connectivity check link, a check across all tunnels, available across all onboarded devices, occurs every ten minutes.


CDO prompts a notification if a VPN tunnel’s connection goes down. However, there is no notification prompt if the link is back up.
