Entity MIB Objects
4
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.
Note Set to serial number and part number (if available), respectively.
entPhysicalMfgName
OID 1.3.6.1.2.1.47.1.1.1.1.12
Status Current
Description 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.
Note Set to empty string.
entPhysicalModelName
OID 1.3.6.1.2.1.47.1.1.1.1.13
Status Current
Description 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.
Note Set to serial number and part number (if available) respectively.
