Entity MIB Objects
4
Description Information about a particular physical equipment, logical entity to external identifier
binding. Each logical entity/physical component pair might be associated with one
alias mapping. The logical entity index might also be used as a wildcard (refer to the
entAliasLogicalIndexOrZero object description for details.)
Note that only entPhysicalIndex values that represent physical ports (that is,
associated entPhysicalClass value is “port(10)”) are permitted to exist in this table.

OID 1.3.6.1.2.1.47.1.3.2.1.1
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 nonzero 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 might exist:
entAliasMappingIdentifier.33.0 = ifIndex.6
entAliasMappingIdentifier.33.4 = ifIndex.1
entAliasMappingIdentifier.33.5 = ifIndex.1
entAliasMappingIdentifier.33.10 = ifIndex.12
Note that entries with nonzero 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
Description The value of this object identifies a particular conceptual row associated with the
indicated entPhysicalIndex and entLogicalIndex pair.
Since only physical ports are modeled in this table, only entries that represent
interfaces or ports are allowed. If an ifEntry exists on behalf of a particular physical
port, then this object should identify the associated ifEntry. For repeater ports, the
appropriate row in the rptrPortGroupTable should be identified instead.
