4 entPhysicalModelName 1.3.6.1.2.1.47.1.1.1.1.13 Note that comparisons between instances of the entPhysicalModelName, entPhysicalFirmwareRev, entPhysicalSoftwareRev, and the entPhysicalSerialNum objects are meaningful only amongst entPhysicalEntries with the same value of entPhysicalMfgName. If the manufacturer name string associated with the physical component is unknown to the agent, then this object contains a zero-length string. Set to empty string. entPhysicalModelName 1.3.6.1.2.1.47.1.1.1.1.13 The vendor-specific model name associated with this physical component. The preferred value is the customer-visible part number, which might be printed on the component. If the model name string associated with the physical component is unknown to the agent, then this object contains a zero-length string. Set to serial number and part number (if available) respectively. entPhysicalAlias 1.3.6.1.2.1.47.1.1.1.1.14 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 reinitializations/reboots of the network management system, including those that result in a change of the physical entity's entPhysicalIndex value. Set to empty string. entPhysicalAssetID 1.3.6.1.2.1.47.1.1.1.1.15 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. 4-12 Fabric OS MIB Reference Publication Number: 53-1000241-01
