by at most one instantiation of each of a particular set of MIB objects. A set

of management functions is associated with each logical entity. Examples of

logical entities include routers, bridges, print-servers, etc.

- Physical Entity

A "physical entity" or "physical component" represents an identifiable

physical resource within a managed system. Zero or more logical entities

may utilize a physical resource at any given time. It is an implementation-

specific manner as to which physical components are represented by an

agent in the EntPhysicalTable. Typically, physical resources (e.g.,

communications ports, back planes, sensors, daughter-cards, power

supplies, the overall chassis) that can be managed via Functions associated

with one or more logical entities are included in the MIB.

- Containment Tree

Each physical component may be modeled as 'contained' within another

physical component. A "containment-tree" is the conceptual sequence of

entPhysicalIndex values that uniquely specifies the exact physical location of

a physical component within the managed system. It is generated by

'following and recording' each 'entPhysicalContainedIn' instance 'up the tree

towards the root', until a value of zero indicating no further containment is

found.
