Configuring System Information

• The collector can analyze traffic patterns for whatever protocols are found in the headers (e.g. TCP/IP,

IPX, Ethernet, AppleTalk…), which means there is no need for a layer 2 switch to decode and

understand all protocols.

sFlow Agent Summary

Packet Flow Sampling and Counter Sampling are performed by sFlow Instances associated with

individual data sources within the sFlow Agent. Packet Flow Sampling and Counter Sampling are

designed as part of an integrated system. Both types of samples are combined in sFlow datagrams. Packet

Flow Sampling will cause a steady, but random, stream of sFlow datagrams to be sent to the sFlow

Collector. Counter samples may be taken opportunistically in order to fill these datagrams.
In order to perform Packet Flow Sampling, an sFlow Sampler Instance is configured with a Sampling

Rate. The Packet Flow sampling process results in the generation of Packet Flow Records. In order to

perform Counter Sampling, the sFlow Poller Instance is configured with a Polling Interval, The Counter

Sampling process results in the generation of Counter Records. The sFlow Agent collects Counter

Records and Packet Flow Records and sends them in the form of sFlow datagrams to sFlow Collectors.
