About Network Node Entity Type Limitations

You can limit the kinds of entities that a network node can represent. UIM uses the list of specifications with which a Network Node specification has relationships to restrict the entity types to which a node instance can be associated. If a relationship exists between a Network Node specification and a specification of any of the entity types a network node can represent, UIM allows the network node instance to be associated only with instances of the related specifications.

If a Network Node specification does not include any relationships to the entity types a network node can represent, then UIM allows node instances to be associated with any of the allowable entity types. See "Defining Specification Relationships" for more information about relationships.
