Beginning with the Cisco SD-AVC 3.0.0 release, SD-AVC connects to a cloud service provided by Cisco that improves traffic
classification. The server addresses used by public internet sites and services change continually. Cisco Cloud Connector
uses the latest information available to improve SD-AVC classification of traffic previously classified only in generic terms.
For example, without Cloud Connector enabled, traffic from a web application using an unknown server might be classified simply
as SSL, without any additional details. When enabled, Cloud Connector might be able to provide additional up-to-date details
about this traffic.
To benefit from this service, enable the Cloud Connector in SD-AVC.
By default, SD-AVC shares telemetry with the cloud service to improve classification throughout the network.
The Cloud Connector setup provides an option to select the location for storing your telemetry data, for compliance with EU
General Data Protection Regulation (GDPR) regulations.
Enabling Cloud Connector in SD-AVC also enables the MS Office 365 Web Service, which was configured separately in earlier
Telemetry Data Collection
The NBAR component of SD-AVC is configured to automatically connect and transmit telemetry data, in near real time, to Cisco.
Telemetry information will be used by Cisco to improve SD-AVC functionality and facilitate development of new features that
result in increased value. Telemetry information is transported securely to keep customer data private. Data collected includes
general administrative information (such as SD-AVC IP address and telemetry status), cache rules (such as application name,
IP addresses, and socket rating), unclassified and generic traffic (such as SSL and HTTP), analytics protocol discovery (such
as number of active flows, number of TCP flows, and number of DNS flows), device information (such as deployed engine versions),
and protocols information (such as application name and application attributes). Users may opt out of data collection for
certain telemetry categories by turning this feature off in the “Settings” tab on the “Cloud Connector” page.
