After filtering nodes, the network interaction map displays only the nodes that satisfy the defined filter settings. In addition, for a node to be displayed on the network interaction map, it must have a connection (link) with another displayed node. If, according to the specified filtering parameters, the network interaction map does not display any node with which a node has interacted, this node is also not displayed on the network interaction map. Filtering is applied similarly for nodes that are part of a consolidated node of unknown devices: if the network map does not display all nodes with which a node of an unknown device has interacted, this node is removed from the list of nodes within the consolidated node of unknown devices.
If necessary, you can enable the network interaction map to display all nodes associated with filtered nodes. Together with the nodes that satisfy the defined node filtering criteria, the network interaction map also displays all nodes with which these nodes have interactions (irrespective of the defined filter settings).
For example, if the nodes are filtered by the PLC category and you enabled the display of linked nodes, the network interaction map will display all nodes that have communicated with PLC category devices. If the display of linked nodes is disabled, the network interaction map will display nodes corresponding only to those PLC category devices that have communicated with each other.
To enable or disable the display of nodes associated with filtered nodes:
Use the Linked devices toggle switch in the toolbar located above the network interaction map.
