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:
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 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.
A basic packet sampling Netflow based implementation.
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
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.
