Overview
Note:
sFlow is only available on certain devices. To check whether your device supports this feature, refer to
the actual web interface. If sFlow is available, there is MAINTENANCE > sFlow in the menu structure.
sFlow (Sampled Flow) is a technology for monitoring high-speed switched and routed
networks. It provide complete visibility into network activity. With sFlow, you can analyze
traffic statistics and monitor the network usage, thus implement effective management
and control of network resources.
The sFlow monitoring system consists of an sFlow Agent and an sFlow Collector.
sFlow Agent
The sFlow Agent is embedded in a switch or router or in a standalone probe. It uses
sampling technology to capture traffic statistics from the device it is monitoring,
and packages the sampled data into sFlow datagrams. sFlow datagrams are used to
immediately forward the sampled data to an sFlow Collector for analysis.
The switch provides a packet-based sFlow, which samples one packet out of a specified
number of packets.
sFlow Collector
The sFlow Collector is installed in a host. It analyzes sFlow datagrams to produce a rich,
real-time, network-wide view of traffic flows.
