Containment is a special kind of relationship that must observe special rules,
and is used to name managed object instances All relationships used for
naming are containment, but not all containment relationships are used for
naming.
Every containment relationship is by nature hierarchical - managed object
instances are contained in other instances which may in turn be contained in
other instances. This characteristic does not necessarily apply to other
relationships.
Containment may be physical or logical, but may generally be described with
the phrase ;SPM_quot;is-part-of;SPM_quot;. The following are examples of containment
relationships
-
line-card A IS-PART-OF multiplexer B
-
circuit C IS-PART-OF circuit D
-
circuit E IS-PART-OF network F
-
customer G IS-PART-OF enterprise H
-
enterprise I IS-PART-OF enterprise J
A managed object contained in an object that is itself contained in a third
object is considered to be contained in the third object. That is, containment
relationships are transitive.
