Information About Software-Defined Application Visibility and Control
Software-Defined Application Visibility and Control (SD-AVC) is a network-level AVC controller that aggregates application data from multiple devices and sources and provides composite application information.
SD-AVC collects application data from across the network and deploys protocol pack updates in a centralized manner. SD-AVC recognizes most enterprise network traffic and provides analytics, visibility, and telemetry into the network application recognition. SD-AVC profiles all the endpoints (including wireless bridged virtual machines) connected to the access nodes to perform anomaly detection operations, such as Network Address Translation (NAT). SD-AVC can discover and alert when the same MAC address is used simultaneously on different networks.
You can enable the Software-Defined Application Visibility and Control feature on a per-WLAN basis. Also, you can turn on and turn off the Software-Defined Application Visibility and Control functionalities independently.
If the SD-AVC process (stilepd) crashes, Capwapd process restart or AP reload is required to resume the SD-AVC operation.
