Entity Mibs - Dell PowerEdge M IO Aggregator Command Reference Manual

Entity MIBS

The Entity MIB provides a mechanism for presenting hierarchies of physical entities using SNMP tables.
The Entity MIB contains the following groups, which describe the physical elements and logical elements
of a managed system The following tables are implemented for the Aggregator.
• 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. Determining which physical components are represented by an agent in the EntPhysicalTable is
an implementation-specific matter. Typically, physical resources (e.g., communications ports,
backplanes, sensors, daughter-cards, power supplies, the overall chassis), which 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.
