Configuring sFlow
Sampled Flow (sFlow) is a traffic monitoring technology used to collect and analyze traffic statistics.
As shown in
Figure 51 , the sFlow system involves an sFlow agent embedded in a device and a remote
sFlow collector. The sFlow agent collects interface counter information and packet content information
and encapsulates the sampled information in sFlow packets. When the sFlow packet buffer is full, or the
aging timer of sFlow packets expires, the sFlow agent sends the sFlow packets in UDP datagrams to the
specified sFlow collector. The sFlow collector analyzes the information and displays the results.
sFlow provides the following sampling mechanisms:
• Flow sampling—Obtains packet content information.
• Counter sampling—Obtains interface counter information.

sFlow has the following advantages:
• Supports traffic monitoring on Gigabit and higher-speed networks.
• Provides good scalability to allow one sFlow collector to monitor multiple sFlow agents.
• Saves money by embedding the sFlow agent in a device, instead of using a dedicated sFlow agent
device.
The device supports only the sFlow agent function.
