Forming a topology map
A topology map is a visual representation of the physical connections between devices in the industrial network. In contrast to the network interactions map, the topology map is intended for displaying the actual connections between devices via network cables connected to the ports of network interfaces. After generating a topology map, you will see one or more graphs that visually display the structure of connections between devices via network equipment such as switches, hubs, routers, and others.
The following objects may be displayed on the topology map:
- Nodes. These objects represent devices and network equipment.
- Links. These objects represent the physical connections between nodes.
Nodes are constantly displayed on the topology map regardless of whether or not these nodes have connections to other nodes. Nodes can be filtered for a more convenient display. Nodes are also distinguished in various ways on the topology map depending on their types, statuses, and events related to the nodes.
After links are added for nodes, you can arrange these nodes on the topology map according to a topology generation procedure.
The topology map is displayed on the Topology map tab in the Network map section.
Data for adding connections to the topology map can be obtained automatically based on the results of active polling of devices – if the corresponding polling methods are used (for example, polling via SNMP). You can also add connections manually.
