4 entLPMappingEntry 1.3.6.1.2.1.47.1.3.1.1 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 (since the entPhysicalContainedIn hierarchy can provide the same information). If, however, more than one bridge was 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 1.3.6.1.2.1.47.1.3.1.1 Index Information about a particular logical entity to physical equipment association. Note that the nature of the association is not specifically identified in this entry. It is expected that sufficient information exists in the MIBs used to manage a particular logical entity to infer how physical component information is utilized. entLogicalIndex entLPPhysicalIndex entLPPhysicalIndex 1.3.6.1.2.1.47.1.3.1.1.1 The value of this object identifies the index value of a particular entPhysicalEntry associated with the indicated entLogicalEntity. entAliasMappingTable 1.3.6.1.2.1.47.1.3.2 This table contains zero or more rows, representing mappings of logical entity and physical component to external MIB identifiers. Each physical port in the system might 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. entAliasMappingEntry 1.3.6.1.2.1.47.1.3.2.1 Index 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 (see "entAliasLogicalIndexOrZero 1.3.6.1.2.1.47.1.3.2.1.1" on page 4-16 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. entPhysicalIndex entAliasLogicalIndexOrZero entAliasLogicalIndexOrZero 1.3.6.1.2.1.47.1.3.2.1.1 The value of this object identifies the logical entity that defines the naming scope for the associated instance of the entAliasMappingIdentifier object. 4-16 Fabric OS MIB Reference Publication Number: 53-1000241-01
