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 analytics. 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 appliance analyzes the received traffic to produce a telemetry stream for Cisco DNA Center that is sent via the appliance's network interface.
The platform supports 20-Gbps sustained forwarding data traffic through the chassis and comes in a 1-Rack-Unit (1RU) form factor. The appliance has six built-in 1-Gbps Small Form Factor (SFP)-only interfaces (these do not support SFP+), and two built-in 10-Gbps Enhanced SFP (SFP+) interfaces (these support only the 10-Gbps rate) that support Synchronous Ethernet (SyncE). The device comes with one copper Ethernet 10/100/1000 Mbps network management port and supports storage extension through the network interface module (NIM) slot.
