Object
column Integer32
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 (e.g.,
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, e.g.:
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 zero-indexed entries. In
this example, all logical entities except 4, 5, and 10
associate physical entity 33 with ifIndex.6.
