Preface

First Published: March 29, 2013

Revised: March 26, 2015

 

This preface describes who should read the Cisco Application Visibility and Control Field Definition Guide, how it is organized, and its document conventions. It contains the following sections:

Objective

The Cisco Application Visibility and Control (AVC) solution is available in the Cisco ISR G2 and the Cisco ASR 1000 Series Aggregation Services Routers. It uses stateful Deep Packet Inspection (DPI) called Cisco Next Generation Network-Based Application Recognition (NBAR2) to identify, analyze, and optimize application traffic. The information gathered in NBAR2 along with performance metrics are exported through standard flow records format, such as NetFlow Version 9 and Internet Protocol Flow Information Export (IPFIX), which can be processed by Cisco Prime or third-party reporting tools.

The objective of this guide is to provide an overview of and describe the metrics and Flexible NetFlow (FNF) IDs exported by Cisco ISR G2 and the Cisco ASR 1000 Series Aggregation Services Routers.

This document covers AVC exports for MMA which is a normalization of exported data for Cisco IOS and IOS XE releases.
