sFlow configuration example

Network requirements

As shown in
Ten-GigabitEthernet 1/1/5 of the device to monitor traffic on the port. Configure the device to send
sampled information in sFlow packets through Ten-GigabitEthernet 1/1/7 to the sFlow collector.
Figure 32 Network diagram

Configuration procedure

1. Configure the IP addresses and subnet masks for interfaces, as shown in
shown.)
2. Configure the sFlow agent and configure information about the sFlow collector:
# Configure the IP address for the sFlow agent.
<Sysname> system-view
[Sysname] 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.
[Sysname] 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 1/1/5.
[Sysname] interface ten-gigabitethernet 1/1/5
[Sysname-Ten-GigabitEthernet1/1/5] sflow counter interval 120
# Specify sFlow collector 1 for counter sampling.
[Sysname-Ten-GigabitEthernet1/1/5] sflow counter collector 1
4. Configure flow sampling:
# Enable flow sampling and set the flow sampling mode to random and sampling interval to
4000.
[Sysname-Ten-GigabitEthernet1/1/5] sflow sampling-mode random
[Sysname-Ten-GigabitEthernet1/1/5] sflow sampling-rate 4000
# Specify sFlow collector 1 for flow sampling.
[Sysname-Ten-GigabitEthernet1/1/5] sflow flow collector 1
