Using Network Setup

Working with Sets

The Network Setup database uses set entities to store collections of other entity references. When network entities are grouped into sets, they can be activated and deactivated as a group. All of the network entities in all of the sets reside in a single area, so there are no limits on the way entities can be grouped. For example, a single network connection entity can be referenced by multiple sets.

IMPORTANT

Sets contain entity references — not the entities themselves. ▲

Figure 2-1 shows the relationship between set entities, network connection entities, and global protocol entities.
