This table contains one row per logical entity.  For agents
that implement more than one naming scope, at least one
entry must exist.  Agents that instantiate all MIB objects
within a single naming scope are not required to implement
this table.

may be managed by this agent or other SNMP agents (possibly)
in the same chassis.

entLPMappingTable

table
.1.3.6.1.2.1.47.1.3.1 · 1 row entry · 1 columns
Open in standard view 
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, which are used to realize that logical
entity.
          
An agent should limit the number and nature of entries in
this table such that only meaningful and non-redundant
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, which 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 (because
the entPhysicalContainedIn hierarchy can provide the same
information).  On the other hand, if more than one bridge
were 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 entry .1.3.6.1.2.1.47.1.3.1.1
Information about a particular logical-entity-to-physical-
equipment association. Note that the nature of the
association is not specifically identified in this entry.

mappings of logical entities and physical components to
external MIB identifiers.  Each physical port in the system
may 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.
