This example describes how to configure and use sFlow monitoring. Junos OS fully
supports the sFlow standard described in RFC 3176,
InMon Corporation's sFlow: A Method
for Monitoring Traffic in Switched and Routed Networks
(see
http://faqs.org/rfcs/rfc3176.html
).

One EX Series switch
Overview and Topology
sFlow technology is a statistical-sampling–based network monitoring technology for
high-speed switched or routed networks. sFlow technology samples network packets
and sends the samples to a monitoring station. The information gathered is used to
create a network traffic visibility picture.
An sFlow monitoring system consists of an sFlow agent embedded in the switch and a
centralized collector. The sFlow agent runs on the switch. It combines interface counters
and flow samples and sends them across the network to the sFlow collector. Figure 88
on page 3581 depicts the basic elements of the sFlow system.
