This example uses the following hardware and software components:
One EX Series switch
Junos OS Release 9.3 or later for EX Series switches
sFlow technology samples network packets and sends the samples to a monitoring
station. You can specify sampling rates for ingress and egress packets. 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 1 on page 28 depicts the basic elements of the sFlow system.
