Cisco Product Identification Standard
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. Table 1-2 lists the UDI elements.
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 may 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 SNs for service and replaceable products
–
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 version ID (VID), which provides version visibility to
help you understand and manage product changes. The VID management ensures consistency of
changes from product to product.
• Operating expense reduction— The Cisco UDI provides accurate and detailed network inventory
information; identifying each Cisco product in a network element through a standard interface.
Cisco operating systems can view and use this data, allowing you to automate your electronic
inventory.
