Currently, the LS81VSNP boards installed in S7500 series switches support the
Netstream feature. In this manual, the LS81VSNP board is called LPU.
2.1 Netstream Overview
2.1.1 Introduction to Netstream
Netstream is a traffic statistics feature. It classifies the traffic flow through the switch into
different streams according to the source IP address and port number, destination IP
address and port number, protocol number and type of service (ToS) in packets, and
collects traffic statistics about each stream independently.
Figure 2-1 depicts the basic procedure of Netstream data collection and analysis.

Figure 2-1 Procedure of Netstream data collection and analysis
The procedure is as follows:
1) The switch collects information about each stream and periodically sends the
information to a Netstream collector (NSC).
2) The NSC processes the information it received, and then sends the resulting data
to the Netstream data analyzer (NDA).
