Unique Device Identifier Retrieval

Unique Device Identifier Retrieval

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.

Finding Feature Information

Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and 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 module.

Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to www.cisco.com/​go/​cfn. An account on Cisco.com is not required.

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:

  • 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.

Information About Unique Device Identifier Retrieval

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 subentities like slots. A Fast 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.

How to Retrieve the Unique Device Identifier

Retrieving the Unique Device Identifier

Perform this task to retrieve and display identification information for a Cisco product.

SUMMARY STEPS

    1.    enable

    2.    show inventory [raw] [entity]


DETAILED STEPS
    Step 1   enable

    Enters privileged EXEC mode. Enter your password if prompted.



    Example:
    Router> enable
    
    Step 2   show inventory [raw] [entity]

    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.



    Example:
    Router# show inventory
    NAME: “Chassis”, DESCR: “12008/GRP chassis”
    PID: GSR8/40           ,  VID: V01,  SN: 63915640
    NAME: “slot 0”, DESCR: “GRP”
    PID: GRP-B             ,  VID: V01,  SN: CAB021300R5
    NAME: “slot 1”, DESCR: “4 port ATM OC3 multimode”
    PID: 4OC3/ATM-MM-SC    ,  VID: V01,  SN: CAB04036GT1
    NAME: “slot 3”, DESCR: “4 port 0C3 POS multimode”
    PID: LC-4OC3/POS-MM    ,  VID: V01,  SN: CAB014900GU
    NAME: “slot 5”, DESCR: “1 port Gigabit Ethernet”
    PID: GE-GBIC-SC-B      ,  VID: V01,  SN: CAB034251NX
    NAME: “slot 7”, DESCR: “GRP”
    PID: GRP-B             ,  VID: V01,  SN: CAB0428AN4O
    NAME: “slot 16”, DESCR: “GSR 12008 Clock Scheduler Card”
    PID: GSR8-CSC/ALRM     ,  VID: V01,  SN: CAB0429AUYH
    NAME: “sfslot 1”, DESCR: “GSR 12008 Switch Fabric Card”
    PID: GSR8-SFC          ,  VID: V01,  SN: CAB0428ALOS
    NAME: “sfslot 2”, DESCR: “GSR 12008 Switch Fabric Card”
    PID: GSR8-SFC          ,  VID: V01,  SN: CAB0429AU0M
    NAME: “sfslot 3”, DESCR: “GSR 12008 Switch Fabric Card”
    PID: GSR8-SFC          ,  VID: V01,  SN: CAB0429ARD7
    NAME: “PSslot 1”, DESCR: “GSR 12008 AC Power Supply”
    PID: FWR-GSR8-AC-B     ,  VID: V01,  SN: CAB041999CW
    

    Enter the show inventorycommand 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 module RO argument string is displayed.



    Example:
    Router# show inventory “module RO”
    NAME: ''module R0'', DESCR: ''Cisco ASR1000 Route Processor 2'' 
    PID: ASR1000-RP2 ,  VID: V01,  SN: JAE13041JEX 
    
    Note   

    The raw keyword option is primarily intended for troubleshooting problems with the show inventory command itself.



    Example:
    Router# show inventory raw
    NAME: “Chassis”, DESCR: “12008/GRP chassis”
    PID:                   ,  VID: V01,  SN: 63915640
    NAME: “slot 0”, DESCR: “GRP”
    PID:                   ,  VID: V01,  SN: CAB021300R5
    NAME: “slot 1”, DESCR: “4 port ATM OC3 multimode”
    PID: 4OC3/ATM-MM-SC    ,  VID: V01,  SN: CAB04036GT1
    NAME: “slot 3”, DESCR: “4 port 0C3 POS multimode”
    PID: LC-4OC3/POS-MM    ,  VID: V01,  SN: CAB014900GU
    

    Troubleshooting Tips

    Commands requiring a delimiting character (the d argument) are used throughout this chapter. Any character can be used as the delimiting character, but we recommend the use of the quote sign ("), because this character is unlikely to be needed within the message itself. Other commonly used delimiting characters include the percent sign (%) or the forward slash (/), but because these characters have meanings within certain Cisco IOS commands, they are not recommended. For example, to set the vacant message to This terminal is idle you would enter the command vacant-message"Thisterminalisidle".
