2.8 sFlow Configuration
2.8.1 sFlow introduction
The sFlow (RFC 3176) is a protocol based on standard network export and used on
monitoring the network traffic information developed by the InMon Company.The
monitored switch or router sends date to the client analyzer through its main operations
such as sampling and statistic, then the analyzer will analyze acconrding to the user
requirements so to monitor the network.
A sFlow monitor system includes: sFlow proxy, central data collector and sFlow
analyzer. The sFlow proxy collects data from the switch using sampling technology. The
sFlow collector is for formatting the sample data statistic which is to be forwarded to the
sFlow analyzer which will analyze the sample data and perform corresponding measure
according to the result. Our switch here acts as the proxy and central data collector in the
sFlow system.
