Description: This MIB provides a method to configure Netflow-lite feature and get information in these areas:

1. Exporter config information and statistics. 2. Sampler config information. 3. Monitor config information and statistics.

The following terms are used throughout this MIB: Flow A flow is defined as a unidirectional sequence of packets between a given source and destination endpoints. Network flows are highly granular; flow endpoints are identified both by IP address as well as by transport layer application port numbers. Netflow also utilizes the IP Protocol type, Type of Service (ToS) and the input interface identifier to uniquely identify flows.

Netflow Netflow is a network protocol developed by Cisco to run on Cisco equipment for collecting IP traffic flow. With the Netflow feature enabled, Netflow records are generated, then exported in User Datagram Protocol(UDP) or Stream Control Transmission Protocol(SCTP) packets and collected using a Netflow collector.

Netflow-lite A basic packet sampling Netflow based implementation.

Exporter A device (for example, a router or a switch) with Netflow services enabled. The exporter monitors packets entering an observation point and creates flows out of these packets. The information from these flows are exported in the form of Flow Records to the collector.

Template Netflow Version 9 Export format is template based. Version 9 record format consists of a packet header followed by at least one or more template or data FlowSets. A template FlowSet (collection of one or more template) provides a description of the fields that will be present in future data FlowSets. Templates provide an extensible design to the record format, a feature that should allow future enhancements to Netflow services without requiring concurrent changes to the basic flow-record format.
