sFlow configuration example
Network requirements
As shown in Figure 58 , configure flow sampling in random mode and counter sampling on Ethernet 1/1
of the device to monitor traffic on the port. Configure the device to send sampled information in sFlow
packets through Ethernet 1/3 to the sFlow collector.
Figure 58 Network diagram
Configuration procedure
1. Configure the IP addresses and subnet masks for interfaces, as shown in Figure 58 . (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
[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 Ethernet 1/1.
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] sflow counter interval 120
# Specify sFlow collector 1 for counter sampling.
[Sysname-Ethernet1/1] sflow counter collector 1
4. Configure flow sampling:
# Enable flow sampling and set the flow sampling mode to random and sampling interval to
4000.
[Sysname-Ethernet1/1] sflow sampling-mode random
[Sysname-Ethernet1/1] sflow sampling-rate 4000
# Specify sFlow collector 1 for flow sampling.
[Sysname-Ethernet1/1] sflow flow collector 1
