4 entPhysicalMfgName 1.3.6.1.2.1.47.1.1.1.1.12 On the first instantiation of a physical entity, the value of entPhysicalSerialNum associated with that entity is set to the correct vendor-assigned serial number, if this information is available to the agent. If a serial number is unknown or nonexistent, the entPhysicalSerialNum is set to a zero-length string instead. Note that implementations that can correctly identify the serial numbers of all installed physical entities do not need to provide write access to the entPhysicalSerialNum object. Agents that cannot provide nonvolatile storage for the entPhysicalSerialNum strings are not required to implement write access for this object. Not every physical component has a serial number or even needs 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 serial number. An agent does not have to provide write access for such entities and might return a zero-length string. If write access is implemented for an instance of entPhysicalSerialNum and a value is written into the instance, the agent must retain the supplied value in the entPhysicalSerialNum 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 serial number and part number (if available), respectively. NOTE For the Brocade 4024 blade, entPhysicalSerialNum displays the vendor-specific serial number; for other switches it displays the factory serial number. entPhysicalMfgName 1.3.6.1.2.1.47.1.1.1.1.12 The name of the manufacturer of this physical component. The preferred value is the name actually printed on the component (if present). 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. 118 Fabric OS MIB Reference 53-1001339-01
