Flow Sampling Commands
4-103
4
Flow sampling (sFlow) can be used with a remote sFlow Collector to provide an
accurate, detailed and real-time overview of the types and levels of traffic present on
the network. The sFlow Agent samples 1 out of
n
packets from all data traversing the
switch, re-encapsulates the samples as sFlow datagrams and transmits them to the
sFlow Collector. This sampling occurs at the internal hardware level where all traffic
is seen, whereas traditional probes only have a partial view of traffic as it is sampled
at the monitored interface. Moreover, the processor and memory load imposed by
the sFlow agent is minimal since local analysis does not take place

sflow source
*
* Due to the switch’s hardware design, these commands can only be enabled for specific port groups (1-8, 9-16,
17-24, 25-32, 33-48). However, sampling for each of the Gigabit combination ports (25-28/49-52) can be controlled
individually.
Enables sFlow on the source ports to be monitored
