What is a capability of Cisco AVC?

Cisco Application Visibility and Control (AVC) is a feature set on Cisco IOS and IOS XE platforms that combines Network-Based Application Recognition (NBAR), Flexible NetFlow (FNF), and performance monitoring to identify applications. This deep visibility then enables administrators to implement granular Quality of Service (QoS) policies, including bandwidth enforcement, based on specific application requirements.

While AVC can operate in environments with VPNs, its core capability is not specifically 'interoperat[ing] by using GET VPN on tunnel interfaces' as a distinguishing feature.

Traffic filtering using a Security Intelligence policy is typically a function of firewalls or specific threat intelligence services like Cisco Talos, not the primary and distinct capability of AVC.

While AVC uses deep packet inspection (DPI) to identify applications, its main capability is not general 'deep packet inspection on IPsec encapsulated traffic' for security purposes, but rather application identification and control.
