The Unique Device Identifier Retrieval feature provides the ability to retrieve and display the Unique Device Identifier (UDI) information from any Cisco product that has electronically stored such identity information.
History for Unique Device Identifier Retrieval Feature
This feature was introduced.
This feature was integrated into Cisco IOS Release 12.0(27)S.
This feature was integrated into Cisco IOS Release 12.2(25)S.
This feature was integrated into Cisco IOS Release 12.2(27)SBC.
This feature was integrated into Cisco IOS Release 12.2(18)SXE5.
Software images for Cisco 12000 series Internet routers have been deferred to Cisco IOS Release 12.0(27)S1.

Prerequisites for Unique Device Identifier Retrieval
In order to use UDI retrieval, the Cisco product in use must be UDI-enabled. A UDI-enabled Cisco product supports five required Entity MIB objects. The five Entity MIB v2 (RFC-2737) objects are as follows:
Although the showinventory command may be available, using that command on devices that are not UDI-enabled will likely produce no output.
Information About Unique Device Identifier Retrieval
Each identifiable product is an entity, as defined by the Entity MIB (RFC-2737) and its supporting documents. Some entities, such as a chassis, will have subentities like slots. An Ethernet switch might be a member of a superentity like a stack. Most Cisco entities that are orderable products will leave the factory with an assigned UDI. The UDI information is printed on a label that is affixed to the physical hardware device, and it is also stored electronically on the device in order to facilitate remote retrieval.
A UDI consists of the following elements:
Product identifier (PID)
Version identifier (VID)
Serial number (SN)
The PID is the name by which the product can be ordered; it has been historically called the “Product Name” or “Part Number.” This is the identifier that one would use to order an exact replacement part.
The VID is the version of the product. Whenever a product has been revised, the VID will be incremented. The VID is incremented according to a rigorous process derived from Telcordia GR-209-CORE, an industry guideline that governs product change notices.
The SN is the vendor-unique serialization of the product. Each manufactured product will carry a unique serial number assigned at the factory, which cannot be changed in the field. This is the means by which to identify an individual, specific instance of a product.
Benefits of the Unique Device Identifier Retrieval Feature
Identifies individual Cisco products in your networks.
Reduces operating expenses for asset management through simple, cross-platform, consistent identification of Cisco products.
Identifies PIDs for replaceable products.
Facilitates discovery of products subject to recall or revision.
Automates Cisco product inventory (capital and asset management).
Provides a mechanism to determine the entitlement level of a Cisco product for repair and replacement service.
Perform this task to retrieve and display identification information for a Cisco product.
Enters privileged EXEC mode. Enter your password if prompted.
Enter theshowinventory command to retrieve and display information about all of the Cisco products installed in the networking device that are assigned a PID, VID, and SN. If a Cisco entity is not assigned a PID, that entity is not retrieved or displayed.
Enter theshowinventorycommand with an entity argument value to display the UDI information for a specific type of Cisco entity installed in the networking device. In this example, a list of Cisco entities that match the sfslot argument string is displayed.
You can request even more specific UDI information using theshowinventorycommand with an entity argument value that is enclosed in quotation marks. In this example, only the details for the entity that exactly matches the sfslot 1 argument string are displayed.
Enter theshowinventorycommand with the raw keyword and an entity argument value to display the UDI information for the Cisco entities that are installed in the networking device and that match the argument string, even if they do not contain an assigned PID.
If any of the Cisco products do not have an assigned PID, the output may display incorrect PIDs and the VID and SN elements may be missing, as in the following example.
NAME: "Four Port High-Speed Serial", DESCR: "Four Port High-Speed Serial"
PID: Four Port High-Speed Serial, VID: 1.1, SN: 17202570
NAME: "Serial1/0", DESCR: "M4T"
PID: M4T , VID: , SN:
In the sample output, the PID is exactly the same as the product description. The UDI is designed for use with new Cisco products that have a PID assigned. UDI information on older Cisco products is not always reliable.
Configuration Examples for Unique Device Identifier Retrieval
There are no configuration examples for the UDI Retrieval feature. For sample display output from the show inventory command, see the “Retrieving the Unique Device Identifier” section.
