Vertex group is more than one Vertex. Vertexes in a group communicate with each other without disturbing other groupsas internal client communication. Vertex group sees other Vertex groups (routing table) but commands from other Vertex Groups are not received. Communication between groups is done via TCP/IP. Using groups you can separate communication between floors, areas, etc.
Vertex cluster is a system of up to 25 Vertex controllers. Vertexes in the cluster can be connected into groups Communication between clusters is done via TCP/IP. All Vertexes in one cluster share the same cluster ID - CUID (a Node.js based identifier with collision-resistant communication). Vertexes in a cluster can be divided into groups.
...
After that, you will see all units which you want to configure as groups. You have 15 Vertex groups in one network, so you can create up to 15 stand alone Vertex groups.
Vertex group in netconfig is NOT the same as vertex group in GUI/Node-RED.
...
The last step is sending the configuration to Vertexes with CUID. You can choose to send the configuration with the old CUID or generate a new one (default). It is important when you are replacing one Vertex and don't want to change the setup of a network (generating a new CUID for Vertexes causes creating a new routing table).
