Description

CAUTION:

Enabling tracing can adversely impact scale and performance and may increase security risk. We strongly recommend using the trace, tracing, or traceoptions commands only under the guidance of a JTAC support engineer. After collecting the debug information, immediately disable tracing to minimize risk and restore normal system performance.

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.
