Description
Configure sFlow technology to continuously monitor traffic at wire speed on specified interfaces simultaneously. sFlow data can be used to provide network traffic visibility information. You can configure sample size of the raw packets in the sFlow record. The range varies from 128 bytes to 512 bytes.
Default
sFlow technology is disabled by default.
