Entity MIB Objects

Description This table contains zero or more rows of logical entity to physical equipment
associations. For each logical entity known by this agent, there are zero or more
mappings to the physical resources used to realize that logical entity.
An agent should limit the number and nature of entries in this table such that only
meaningful and nonredundant information is returned. For example, in a system that
contains a single power supply, mappings between logical entities and the power
supply are not useful and should not be included.
Also, only the most appropriate physical component that is closest to the root of a
particular containment tree should be identified in an entLPMapping entry.
For example, suppose a bridge is realized on a particular module and all ports on that
module are ports on this bridge. A mapping between the bridge and the module would
be useful, but additional mappings between the bridge and each of the ports on that
module would be redundant (since the entPhysicalContainedIn hierarchy can provide
the same information). If, however, more than one bridge was utilizing ports on this
module, then mappings between each bridge and the ports it used would be
appropriate.
Also, in the case of a single backplane repeater, a mapping for the backplane to the
single repeater entity is not necessary.
entLPMappingEntry
OID 1.3.6.1.2.1.47.1.3.1.1
Description Information about a particular logical entity to physical equipment association. Note
that the nature of the association is not specifically identified in this entry. It is
expected that sufficient information exists in the MIBs used to manage a particular
logical entity to infer how physical component information is utilized.
Index entLogicalIndex
entLPPhysicalIndex
entLPPhysicalIndex
OID 1.3.6.1.2.1.47.1.3.1.1.1
Description The value of this object identifies the index value of a particular entPhysicalEntry
associated with the indicated entLogicalEntity.
entAliasMappingTable
OID 1.3.6.1.2.1.47.1.3.2
Description This table contains zero or more rows, representing mappings of logical entity and
physical component to external MIB identifiers. Each physical port in the system
might be associated with a mapping to an external identifier, which itself is associated
with a particular logical entity’s naming scope. A wildcard mechanism is provided to
indicate that an identifier is associated with more than one logical entity.
