Orion is licensed by the largest number of the three following object types:

1. Interfaces: interfaces include switch ports, physical interfaces, virtual interfaces, sub-interfaces, VLANs, and any other single point of network traffic. The number of interfaces is typically the highest of the three objects in most deployments.
