sFlow configuration example
Network requirements
As shown in
, perform the following tasks:
•
Configure flow sampling in random mode and counter sampling on GigabitEthernet 1/0/1 of the
device to monitor traffic on the port.
•
Configure the device to send sampled information in sFlow packets through GigabitEthernet
1/0/3 to the sFlow collector.

Configuration procedure
1.
Configure the IP addresses and subnet masks for interfaces, as shown in
. (Details
not shown.)
2.
Configure the sFlow agent and configure information about the sFlow collector:
# Configure the IP address for the sFlow agent.
<Device> system-view
[Device] sflow agent ip 3.3.3.1
# Configure information about the sFlow collector. Specify the sFlow collector ID as 1, IP
address as 3.3.3.2, port number as 6343 (default), and description as
netserver
.
[Device] sflow collector 1 ip 3.3.3.2 description netserver
3.
Configure counter sampling:
# Enable counter sampling and set the counter sampling interval to 120 seconds on
GigabitEthernet 1/0/1.
[Device] interface gigabitethernet 1/0/1
[Device-GigabitEthernet1/0/1] sflow counter interval 120
# Specify sFlow collector 1 for counter sampling.
[Device-GigabitEthernet1/0/1] sflow counter collector 1
4.
Configure flow sampling:
# Enable flow sampling and set the flow sampling mode to random and sampling interval to
4000.
