Explanation
According to the VMware NSX Documentation, these are three of the capabilities of Network Topology, which is a graphical representation of your network infrastructure in NSX:
Display how the different NSX components are interconnected: You can use Network Topology to view how your segments, gateways, routers, firewalls, load balancers, VPNs, and other NSX components are connected and configured in your network.
Display the uplink configured on the Tier-0 Gateways: You can use Network Topology to view the uplink interface and segment that connect your tier-0 gateways to your physical network. You can also view the VLAN ID and IP address of the uplink interface.
Display the VMs connected to Segments: You can use Network Topology to view the VMs that are attached to your segments. You can also view the IP address and MAC address of each VM.
