Page 13: Chapter 1 Overview
Overview This chapter describes the CNS NetFlow Collection Engine application, which is used with the NetFlow services data export feature on Cisco routers and Catalyst 5000 and 6000 series switches. This chapter includes the following sections: • What Are NetFlow Services? What Is CNS NetFlow Collection Engine? •... -
Page 14: Netflow Services Device And Ios Release Support
What Are NetFlow Services? Catalyst 5000 series switches can identify flows by looking at a subset of these fields. For example, they can identify flows by source and destination address only. For Catalyst 5000 series switches, the analog to NetFlow services is integrated Multilayer Switching Note (MLS) management. -
Page 15: Netflow Data Export Formats
Chapter 1 Overview Version 5 datagrams, up to 30 flows can be sent in a single UDP datagram of approximately 1500 • bytes. • Version 7 datagrams, up to 27 flows can be sent in a single UDP datagram of approximately 1500 bytes. -
Page 16: What Is Cns Netflow Collection Engine
What Is CNS NetFlow Collection Engine? Throughout this publication there are numerous examples of CNS NetFlow Collection Engine input Caution commands and output results. Included are examples of IP addresses. Be aware that IP address examples are not usable IP addresses. The examples do not represent real-life configurations. What Is CNS NetFlow Collection Engine? CNS NetFlow Collection Engine provides fast, scalable, and economical data collection from multiple export devices exporting NetFlow data records. -
Page 17: Cns Netflow Collection Engine Architectural Overview
Chapter 1 Overview CNS NetFlow Collection Engine collects and summarizes (aggregates) data into data files based on user-defined criteria specified in a CNS NetFlow Collection Engine aggregator. An aggregator is an aggregation task defined by a set of user-configurable attributes that specify how CNS NetFlow Collection Engine summarizes the traffic flows that are received. -
Page 18: Collector
CNS NetFlow Collection Engine Architectural Overview Figure 1-2 Collector The Collector subsystem collects NetFlow data, aggregates (or summarizes) that data, and filters specified data from supported Cisco routers and switches. Output is stored in files that are organized in an easy-to-use directory structure. Web-Based User Interface The Web-Based User Interface is provided for configuration, control, status, and reporting. -
Page 19: Cns/Xml Interface
Chapter 1 Overview CNS/XML Interface The CNS/XML Interface is used to send and receive configuration/control requests and responses, and unsolicited event notifications. The CNS/XML interface uses the CNS Integration Bus to communicate with clients. Report Generator The Report Generator produces hourly and daily reports based on Collector output files by performing further aggregation of the records in these files based on criteria selected by the user. - Page 20 Chapter 1 Overview CNS NetFlow Collection Engine Architectural Overview Cisco CNS NetFlow Collection Engine User Guide, Release 5.0.2 OL-6899-01...
