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 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

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. 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.


Note
For the following platforms, the UDI is the Printed Circuit Board Number (PCB), and not the chssis Serial Number (SN):

  • ISR 4221

  • ISR 4321

  • ISR 4331

  • ISR 4351

  • ISR 4431

  • ISR 4451

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 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.

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 theshowinventory command 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.

Example:


Router# show inventory sfslot
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

You can request even more specific UDI information using theshowinventory command 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.

Example:


Router# show inventory “sfslot 1”
NAME: “sfslot 1”, DESCR: “GSR 12008 Switch Fabric Card”
PID: GSR8-SFC          ,  VID: V01,  SN: CAB0428ALOS

For diagnostic purposes, theshowinventory command can be used with the raw keyword to display every RFC 2737 entity including those without a PID, UDI, or other physical identification.

Note 

The raw keyword option is primarily intended for troubleshooting problems with the showinventory 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

Enter theshowinventory command 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.

Example:


Router# show inventory raw slot
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

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.
