docsRphyRpdIfPhysEntityContainedIn — CableLabs official current and historical MIBs
The value of docsRphyRpdIfPhysEntityIndex for the physical entity that 'contains' this physical entity. A value of zero indicates this physical entity is not contained in any other physical entity. Note that the set of 'containment' relationships define a strict hierarchy; that is, recursion is not allowed. In the event that a physical entity is contained by more than one physical entity (e.g., double-wide modules), this object should identify the containing entity with the lowest value of docsRphyRpdIfPhysEntityIndex.
