Physical entity group 5 TABLE 39 Object and OID Access entPhysicalAlias Read-write 1.3.6.1.2.1.47.1.1.1.1.14 entPhysicalAssetID Read-write 1.3.6.1.2.1.47.1.1.1.1.15 entPhysicalIsFRU Read only 1.3.6.1.2.1.47.1.1.1.1.16 Description This object is an alias name for the physical entity as specified by a network manager; it provides a nonvolatile handle for the physical entity. On the first instantiation of a physical entity, the value of entPhysicalAlias associated with that entity is set to the zero-length string. However, the agent might set the value to a locally unique default value instead of a zero-length string. If write access is implemented for an instance of entPhysicalAlias and a value is written into the instance, the agent must retain the supplied value in the entPhysicalAlias instance associated with the same physical entity for as long as that entity remains instantiated. This includes instantiations across all re-initializations or reboots of the network management system, including those that result in a change of the physical entity's entPhysicalIndex value. Set to empty string. This object is a user-assigned asset tracking identifier for the physical entity as specified by a network manager; it provides nonvolatile storage of this information. On the first instantiation of a physical entity, the value of entPhysicalAssetID associated with that entity is set to the zero-length string. Not every physical component has an asset tracking identifier or even need one. Physical entities for which the associated value of the entPhysicalIsFRU object is equal to "false (2)" (for example, the repeater ports within a repeater module) do not need their own unique asset tracking identifier. An agent does not have to provide write access for such entities and might instead return a zero-length string. If write access is implemented for an instance of entPhysicalAssetID and a value is written into the instance, the agent must retain the supplied value in the entPhysicalAssetID instance associated with the same physical entity for as long as that entity remains instantiated. This includes instantiations across all re-initializations/reboots of the network management system, including those that result in a change of the physical entity's entPhysicalIndex value. If no asset tracking information is associated with the physical component, then this object contains a zero-length string. Set to empty string. The entPhysicalIsFRU object indicates whether this physical entity is considered a field replaceable unit by the vendor. If this object contains the value "true (1)," then this entPhysicalEntry identifies a field replaceable unit. For all entPhysicalEntries representing components that are permanently contained within a field replaceable unit, the value "false (2)" should be returned for this object. Set to True (1) for FRU entries (port blades, CPs, sensors, power supplies, and fans; False (2) for container and chassis type entries.
