CHAPTER 1
Unique Device Identifier Retrieval
The Unique Device Identifier (UDI) Retrieval feature provides the ability to retrieve and display the UDI
information from any Cisco product that has electronically stored such identity information.
Finding Feature Information
Your software release may not support all the features documented in this module. For the latest feature
information and caveats, see the release notes for your platform and software release. To find information
about the features documented in this module, and to see a list of the releases in which each feature is
supported, see the Feature Information Table at the end of this document.
Use Cisco Feature Navigator to find information about platform support and Cisco software image support.
To access Cisco Feature Navigator, go to http://tools.cisco.com/ITDIT/CFN/. An account on http://
www.cisco.com/ is not required.

Unique Device Identifier Overview
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 sub-entities like slots. An Ethernet switch might be a member of
a super-entity like a stack. Most Cisco entities that can be ordered 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.

Unique Device Identifier Retrieval
Unique Device Identifier Overview

•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.
Product Item Descriptor for Cable Products
For information on the Product Item Descriptor (PID), see the product hardware installation guide available
on Cisco.com.
Retrieving the Unique Device Identifier
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:
•entPhysicalName
•entPhysicalDescr
•entPhysicalModelName
•entPhysicalHardwareRev
•entPhysicalSerialNum
Although the show inventory command may be available, using that command on devices that are not
UDI-enabled will likely produce no output.
Enter the show inventory 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.

For diagnostic purposes, the show inventory command can be used with the raw keyword to display every
RFC 2737 entity including those without a PID, UDI, or other physical identification.
The raw keyword option is primarily intended for troubleshooting problems with the show inventory
command itself.
