6.4 Collecting Statistics About IPv4 Aggregated Flows

Before collecting statistics about IPv4 aggregated flows, familiarize yourself with the applicable
environment, complete the pre-configuration tasks, and obtain the data required for the
configuration. This will help you complete the configuration task quickly and accurately.
Applicable Environment
As shown in
application information. Such information can guide carriers in monitoring abnormal network
traffic, analyzing users' operation mode, and planning the network between ASs.
Statistics collection of NetStream aggregated flows collects statistics about original flows with
the same attributes, whereas statistics collection of NetStream original flows collects statistics
about sampled packets. The data volume generated by aggregated flow statistics collection is
therefore greater than that generated by original flow statistics collection.
