This section describes the usage scenarios of sFlow.

Network Monitoring

Network maintenance personnel often use the traffic monitoring technique to monitor networks.

Enterprise network users often have requirements for traffic on an interface and device running. They require a traffic monitoring technique on an interface to locate unexpected traffic and the source of attack traffic immediately so that they can rectify faults quickly to ensure stable running of the network.

sFlow is an interface-based traffic analysis technique that collects packets on an interface based on the sampling ratio. In flow sampling, an sFlow agent analyzes the packets including the packet content and forwarding rule, and encapsulates the original packets and parsing result into sFlow packets. Then the sFlow agent sends the sFlow packets to an sFlow collector. In counter sampling, an sFlow agent periodically collects traffic statistics on an interface, CPU usage, and memory usage. sFlow focuses on traffic on an interface, traffic forwarding, and device running, so it can be used to monitor and locate network exceptions. The sFlow collector displays the traffic statistics in a report, which helps you locate faults.

As shown in Figure 14-57, before collecting traffic statistics on an interface and analyzing the collected traffic statistics, configure an sFlow agent and connect the sFlow agent to an sFlow collector.
