Unique Device Identifier
The Unique Device Identifier (UDI) is the Cisco product identification standard for hardware products. A
product identification standard removes barriers to enterprise automation and can help you reduce operating
expenses.
The UDI provides a consistent electronic, physical, and associated business-to-business information product
identification standard.
The UDI is a combination of five data elements. The following table lists the UDI elements.
Table 1: UDI Elements
Description Physical
Visibility Electronic
Visibility UDI Data Element
Product ID, also known as product name, model
name, product number Yes Yes PID
Version ID Yes Yes VID
Serial number, the unique instance of the PID Yes Yes SN
Type, such as chassis, slot, or power supply — Yes Entity Name
Additional product information — Yes Product Description
The combination of serial number and product ID (PID) is unique and consistent across all Cisco products.
The PID that is coded on hardware is called a base product identifier.
Additional orderable PIDs can be associated to a base PID. For instance, an orderable PID may describe a
packaging configuration for a product or a bundled group of products sold, tested, and shipped together.
Specific unique device identifier (UDI) benefits include the following:
• Identifies:
◦ Individual Cisco products in your networks
◦ PIDs and serial numbers for service and replaceable products
◦ Version IDs (VIDs) for product version visibility
• Facilitates discovery of products subject to recall or upgrade
• Enhances inventory automation of Cisco products
The Cisco product identification standard provides the following features:
• Version visibility — Cisco continuously improves products through feature additions. Product changes
are indicated by incrementing the VID, which provides version visibility to help you understand and
manage product changes. VID management ensures consistency of changes from product to product.
