Information About Application Visibility and Control in a Wired
Network
Application Visibility and Control (AVC) is a critical part of Cisco's efforts to evolve its Branch and Campus
solutions from being strictly packet and connection based to being application-aware and application-intelligent.
Application Visibility and Control (AVC) classifies applications using deep packet inspection techniques with
the Network-Based Application Recognition (NBAR2) engine. AVC can be configured on wired access ports
for standalone switches. NBAR2 can be activated either explicitly on the interface by enabling
protocol-discovery or implicitly by attaching a QoS policy that contains match protocol classifier. Wired
AVC Flexible NetFlow (FNF) can be configured on an interface to provide client, server and application
statistics per interface. The record is similar to application-client-server-stats traffic monitor which is
available in application-statistics and application-performance profiles in Easy Performance Monitor (Easy
perf-mon or ezPM).
