Description: The value of this object uniquely identifies the logical

entity which defines the naming scope for the associated instance of the 'hpEntAliasMappingIdentifier' object.

If this object has a non-zero value, then it identifies the logical entity named by the same value of hpEntLogicalIndex.

If this object has a value of zero, then the mapping between the physical component and the alias identifier for this hpEntAliasMapping entry is associated with all unspecified logical entities. That is, a value of zero (the default mapping) identifies any logical entity which does not have an explicit entry in this table for a particular hpEntPhysicalIndex/hpEntAliasMappingIdentifier 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:

hpEntAliasMappingIdentifier.33.0 = ifIndex.5

In the event an hpEntPhysicalEntry is associated differently for some logical entities, additional hpEntAliasMapping entries may exist, e.g.:

hpEntAliasMappingIdentifier.33.0 = ifIndex.6 hpEntAliasMappingIdentifier.33.4 = ifIndex.1 hpEntAliasMappingIdentifier.33.5 = ifIndex.1 hpEntAliasMappingIdentifier.33.10 = ifIndex.12

Note that entries with non-zero hpEntAliasLogicalIndexOrZero 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.
