Explanation

Local Network Telemetry: Cisco DNA Center collects data from several different sources and protocols on the local network, including the following: traceroute; syslog; NetFlow; Authentication, Authorization, and Accounting (AAA); routers; Dynamic Host Configuration Protocol (DHCP); Telnet; wireless devices; Command-Line Interface (CLI); Object IDs (OIDs); IP SLA; DNS; ping; Simple Network Management Protocol (SNMP); IP Address Management (IPAM); MIB; Cisco Connected Mobile Experiences (CMX); and AppDynamics ®. The great breadth and depth of data collection allows Cisco DNA Center to give a clearer picture of the state of the network, clients, and applications. This data is kept on the Cisco DNA Center appliance locally (at your location) and is available for a period of 14 days. Local Network Telemetry is not transported to any other server nor is it sent to the cloud.
