Configuring sFlow

sFlow is a traffic monitoring technology.

As shown in

, 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
information and encapsulates the sampled information in sFlow packets. When the sFlow packet
buffer is full, or the aging timer (fixed to 1 second) expires, the sFlow agent performs the following
actions:

•

Encapsulates the sFlow packets in the UDP datagrams.

•

Sends the UDP datagrams to the specified sFlow collector.

The sFlow collector analyzes the information and displays the results. One sFlow collector can
monitor multiple sFlow agents.

sFlow provides the following sampling mechanisms:

•

Flow sampling

—Obtains packet information.

•

Counter sampling

—Obtains interface counter information.

Configuration restrictions and guidelines

When you configure sFlow in an EVPN network, you must specify the source IP address of sFlow
packets by using the

sflow source

command. For information about EVPN, see
