# Configuring sFlow

sFlow is a multi-vendor, packet sampling technology used to monitor network devices including routers, switches, host devices and wireless access points. Flow Monitor traffic monitoring software uses the sFlow data to analyze and manage network traffic and to ensure Quality of Service. 

sFlow sampling process is performed by the switching/routing ASICs, thereby ensuring wire-speed performances. The sFlow agent then combines the interface counters, flow samples and the forwarding/routing table state associated with each packet into a UDP sFlow datagram. This is then sent to the sFlow collector for collection and analysis.
