Cisco DNA Traffic Telemetry Appliance Overview

This chapter contains information about the Cisco DNA Traffic Telemetry Appliance, and contains the following sections:

Information About the Cisco DNA Traffic Telemetry Appliance

The Cisco DNA Traffic Telemetry Appliance is a telemetry sensor platform that is used to generate telemetry from mirrored IP network traffic and share it with Cisco DNA Center for application and endpoint visibility. Network traffic is received from switches and routers via Switched Port Analyzer (SPAN) mirroring and fed into the Cisco DNA Traffic Telemetry Appliance mirroring interfaces. The Cisco DNA Traffic Telemetry Appliance analyzes the received traffic to produce a telemetry stream for Cisco DNA Center that is sent via the appliance network interface.

The Cisco DNA Traffic Telemetry Appliance offers a compact form factor that consumes less rack space and power.

Table 1. Platform Booting Methods
Boot Method Booting Command from ROMMON Supported in IOS XE 17.3.1

Bin boot

rommon> boot bootflash:ttam-universalk9.*.SSA.bin

Yes

Install boot

 rommon> boot bootflash:packages.conf

No

Note

Install boot is not supported in Cisco IOS XE Amsterdam 17.3.1. The impact of this limitation is the boot time: .bin boot takes more time than the Install boot, because the slower ROMMON retrieves the entire ttam-universalk9.*.SSA.bin from the bootflash to the memory.

Cisco DNA Traffic Telemetry Appliance Rear View

The following figure shows the rear of the Cisco DNA Traffic Telemetry Appliance.

Figure 4. Cisco DNA Traffic Telemetry Appliance Rear View

Four internal fans draw cooling air into the chassis and across internal components to maintain an acceptable operating temperature. The fans are located in the center of the chassis. The fans are numbered from 0 to 3, right to left.

Two power supplies, either two AC power supplies or two DC power supplies, are accessed from the rear of the appliance and are hot-swappable.


Note
The Cisco DNA Traffic Telemetry Appliance can support two AC or two DC power supplies. Do not install mixed AC and DC power supply units in the same chassis.

Cisco Product Identification Standard

This section describes the Cisco products and services product identification standard. This feature provides you with the ability to effectively integrate and manage Cisco products in your network and business operations.

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 the data elements shown in the following table.

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 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.

The show diag subslot eeprom command displays the PID, VID, PCB serial number, hardware revision, and other such information.

The following is sample output from the show diag subslot eeprom command: 


Device# show diag subslot 0/0 eeprom
MIDPLANE EEPROM data:
        Product Identifier (PID) : DN-APL-TTA-M

Note
Common Language Equipment Identification (CLEI) code is a ten-digit character code that identifies a specific product. A CLEI code is applied to each part within a Cisco DNA Traffic Telemetry Appliance as they are programmed in manufacturing for shipment to customers.

The show license udi command displays UDI information.

The following is sample output from the show license udi command: 


Device# show license udi
