entityMappingGroup
Implementation of the entPhysicalContainsTable is
mandatory for all agents. Implementation of the
entLPMappingTable and entAliasMappingTables are not
mandatory for agents that model all MIB object instances
within a single naming scope.
Note that the entAliasMappingTable may be useful for all
agents, however implementation of the entityLogicalGroup or
entityLogical2Group is required to support this table.

numbers.
Write access is not required for agents that can identify serial
number information for physical entities, but cannot provide
non-volatile storage for NMS-assigned serial numbers.
Write access is not required for physical entities for which the
associated value of the entPhysicalIsFRU object is equal to
"false(2)."

Write access is required only if the associated
entPhysicalClass value is equal to "chassis(3)."
