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 1-2lists the UDI elements.

Table 1-2	Cisco UDI Elements
		Electronic	Physical
UDI Data Element		Visibility	Visibility	Description
PID		Yes	Yes	Product ID, also known as product name, model
				name, product number
VID		Yes	Yes	Version ID
SN		Yes	Yes	Serial number, the unique instance of the PID (see
				Figure 1-5,Figure 1-7, and Figure 1-6in the next
				section for location of the serial number label)
Entity Name		Yes	No	Type, such as chassis, slot, or power supply
Product Description		Yes	No	Additional product information

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.
