sFlow is a technology for monitoring traffic in data networks containing switches and routers. It relies on statistical sampling of packets from high-speed networks, plus periodic gathering of the statistics.
This feature expands upon sFlow's capability by providing support for additional data structures that an sFlow agent can use to report table utilization statistics in sFlow counter samples (output of the new show command).
