Monitoring the health and connectivity of stretched Layer 2 networks is vital for maintaining seamless hybrid cloud operations.

In a Nutanix environment managed via Prism Central, the specific location to verify the operational status of these extensions is underNetwork and Security, specifically within theNetwork Servicessection labeledSubnet Extensions. This dashboard provides visibility into the VTEP (VXLAN Tunnel Endpoint) gateways and the specific subnets that have been extended from the on-premises environment to NC2 on AWS. Administrators can check if the tunnel is " Up " or " Down " and view performance metrics associated with the stretched segment. Ensuring the status is monitored here allows for rapid troubleshooting of connectivity issues that might prevent virtual machines from communicating across the hybrid link.
