Configuring sFlow

Sampled Flow (sFlow) is a traffic monitoring technology.
As shown in
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 (fixed to one second) 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.
Figure 56 sFlow system
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.
NOTE:
The device supports only the sFlow agent function.
