entPhysicalSerialNum
1.3.6.1.2.1.47.1.1.1.1.11 Read-write The vendor-specific serial number string for the physical entity. The
preferred value is the serial number actually printed on the component
(if present).
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 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 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 Read only 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 Read only 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.
