sFlow configuration example

Network requirements

As shown in

Figure 63

, configure flow sampling in random mode and counter sampling on

Ten-GigabitEthernet 1/0/1 of the device to monitor traffic on the port. Configure the device to send
sampled information in sFlow packets through Ten-GigabitEthernet 1/0/3 to the sFlow collector.

Configuration procedure

1.

Configure the IP addresses and subnet masks for interfaces, as shown in

Figure 63

. (Details not

shown.)

2.

Configure the sFlow agent and configure information about the sFlow collector:
# Configure the IP address for the sFlow agent.

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
Ten-GigabitEthernet 1/0/1.

[Device] interface ten-gigabitethernet 1/0/1

[Device-Ten-GigabitEthernet1/0/1] sflow counter interval 120

# Specify sFlow collector 1 for counter sampling.

[Device-Ten-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.

[Device-Ten-GigabitEthernet1/0/1] sflow sampling-mode random

[Device-Ten-GigabitEthernet1/0/1] sflow sampling-rate 4000

# Specify sFlow collector 1 for flow sampling.

[Device-Ten-GigabitEthernet1/0/1] sflow flow collector 1
