Entity MIB Objects Description The value of this object identifies the logical entity that defines the naming scope for the associated instance of the entAliasMappingIdentifier object. If this object has a non-zero value, then it identifies the logical entity named by the same value of entLogicalIndex. If this object has a value of zero, then the mapping between the physical component and the alias identifier for this entAliasMapping entry is associated with all unspecified logical entities. That is, a value of zero (the default mapping) identifies any logical entity that does not have an explicit entry in this table for a particular entPhysicalIndex/entAliasMappingIdentifier pair. For example, to indicate that a particular interface (such as "physical component 33") is identified by the same value of ifIndex for all logical entities, the following instance might exist: entAliasMappingIdentifier.33.0 = ifIndex.5 In the event an entPhysicalEntry is associated differently for some logical entities, additional entAliasMapping entries may exist, for example: entAliasMappingIdentifier.33.0 = ifIndex.6 entAliasMappingIdentifier.33.4 = ifIndex.1 entAliasMappingIdentifier.33.5 = ifIndex.1 entAliasMappingIdentifier.33.10 = ifIndex.12 Note that entries with non-zero entAliasLogicalIndexOrZero index values have precedence over any zero-indexed entry. In this example, all logical entities except 4, 5, and 10 associate physical entity 33 with ifIndex.6. entAliasMappingIdentifier OID 1.3.6.1.2.1.47.1.3.2.1.2 MIB Version 3.1.x/4.1.x Reference Guide 185
