License type

Best to inquire with Sales on this.  In general there are two types of licenses, one where you get a license for each module you want and each node for that module.   Usually when you get above 1-2000 nodes you'd go with an unlimited license for that module.    This is perpetual licensing

There is also the new licensing model where you purchase a bunch of modules on a per-node basis.     This is their subscription model.

I'll add to this: the "licensing" count (you said "port" or "sensor") depend drastically upon the product in question.  SolarWinds makes over 50 products, so the licensing can be different on each.
