Unique Device Identifier

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.
• Operating expense reduction—Cisco UDIs provide 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.
• Consistency across product layers—The UDIs are embedded in the hardware products and cannot be
overwritten. Operating and management systems discover UDIs through standard interfaces and display
UDIs in standard outputs. Standard interfaces include the IETF standard ENTITY-MIB.
