Procedure

1. From your browser, log in with admin privileges to an NSX Manager at https://<nsx-manager-ip-address>.
2. Select Networking > Network Topology.
3. Navigate through the network topology to see more information:
   • Zoom in to view more details.
   • Point to an entity to view its logical path in the network and view the services configured on it.
   • Click an entity or service to view more details.

     For the IPSec VPN service, NSX-T Data Center displays a visual representation of configuration information like local and remote endpoints and also indicates whether the sessions are Policy-based or Rule-based. You can then click a session to view session-specific details like tunnel status, among others.

   • Click Export on the tool bar to save the topology to a PDF file.
   • Apply filters to focus on specific objects. See Filter by Object Attributes for more details about filters.
