The Netflow Data Export (NDE) MIB provides instrumentation for
configuration and operation of the Netflow Data Export feature.
A network flow is defined as an 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 Data Export refers to the export of Netflow Data using
UDP packets to Netflow Data Collector(s). A NetFlow Data
Collector (NDC) captures, filters, aggregates, and stores the
data from multiple NetFlow enabled devices. NDCs provide fast,
scalable, and economical Netflow data.
