Discovery for servers and network devices

Starting in Fuji, the Layer 3 BSM Discovery feature will map Layer 3 relationships between a server and other network devices. The relationship begins at the router or switch and shows relationship and IP address information for associated servers and network devices.

The system property glide.discovery.L3_mapping toggles the Layer 3 BSM discovery of these devices. When glide.discovery.L3_mapping is true, the relationship created is of type IP Connection::IP Connection. In this example, the BSM resulting from the discovery of Linux Server db14242 shows that it has an IP Connection::IP Connection relationship to switch cor-001a.

Prerequisites

  • The server or network device needs to have IP Address information.
  • The system property glide.discovery.L3_mapping is set to true to discover routers and switches.
  • The router or Layer 3 switch that provides the IP Address needs to have been successfully discovered with populated Exit Interface Routing Rules.

System Properties
