5.12 sFlow

sFlow (ver. 5) is a procedure for statistical monitoring of traffic in networks. MLNX-OS supports

an sFlow sampling mechanism (agent), which includes collecting traffic samples and data from

counters. The sFlow datagrams are then sent to a central collector.

The sampling mechanism must ensure that any packet

going into the system has an equal chance

of being sampled, irrespective of the flow to which it belongs. The sampling mechanism provides

the collector with periodical information on the amount (and load) of traffic per interface by

loading the counter samples into sFlow datagrams.

The sFlow packets are encapsulated and sent in UDP over

IP. The UDP port number that is used

is the standard 6343 by default.
