Entity MIB Objects

For example, suppose a physical port was represented by entPhysicalEntry.3,

entLogicalEntry.15 existed for a repeater, and entLogicalEntry.22 existed for a bridge.

Then there might be two related instances of entAliasMappingIdentifier:

entAliasMappingIdentifier.3.15 ==

rptrPortGroupIndex.5.2

entAliasMappingIdentifier.3.22 == ifIndex.17

It is possible that other mappings (besides interfaces and repeater ports) might be

defined in the future, as required.

Bridge ports are identified by examining the Bridge MIB and appropriate ifEntries

associated with each dot1dBasePort and are thus not represented in this table.

entPhysicalContainsTable

OID 1.3.6.1.2.1.47.1.3.3

Description A table that exposes the container/containee relationships between physical entities.

This table provides all the information found by constructing the virtual containment

tree for a given entPhysicalTable, but in a more direct format.

In the event a physical entity is contained by more than one other physical entity (for

example, double-wide modules), this table should include these additional mappings,

which cannot be represented in the entPhysicalTable virtual containment tree.

entPhysicalContainsEntry

OID 1.3.6.1.2.1.47.1.3.3.1

Description A single container/“containee” relationship.

Index entPhysicalIndex

entPhysicalChildIndex

OID 1.3.6.1.2.1.47.1.3.3.1.1

Description The value of entPhysicalIndex for the contained physical entity. Through this the

containment hierarchy of the physical entities is displayed (see Figure 4-3).
