Configuring sFlow using the CLI
To configure a sFlow enabled device to send sFlow data to Flow Monitor using the
command line interface (CLI):
Caution: This procedure is an example that applies only to an HP ProCurve 3500 switch and
should not be used for other devices. The process for configuring a device to export sFlow
data varies widely from device to device and is dependent upon your network configuration.
The following example uses CLI configuration to enable sFlow on an HP ProCurve 3500 series
switch. The configuration is for Flow Monitor running on a system with IP address
192.168.3.31 and receiving sFlow data on UDP port 9999.
1 Access the sFlow device via the command line interface (CLI).
2 Set the sFlow device IP (sFlow collector) using the following commands.
Command Purpose
(config)# sflow 1 destination
(config)# sflow 1 sampling
ethernet
(config)# sflow 1 polling
ethernet
Configuring sFlow using SNMP
Sets the sFlow receiving device address
(192.168.3.31) and UDP port (9999). For example:
(config)# sflow 1 destination
192.168.3.31 9999
Sets the sFlow sample rate for each interface (1-
24). One out of every 128 packets will be collected
in this example. For example:
(config)# sflow 1 sampling ethernet A1-
A24 128
Sets the sFlow polling interval. Polls every 30
seconds in this example. For example: config)#
sflow 1 polling ethernet A1-A24 30
The following example uses SNMP commands to enable sFlow on an HP ProCurve 2610 series
switch. We recommend configuring the sFlow device via the device OS commands from the
command line interface (CLI); however, some sFlow devices do not include this capability. In
this case, you can use SNMP commands to configure sFlow. This configuration example is for
Flow Monitor running on a system with IP address 192.168.3.31 and receiving sFlow data on
UDP port 9999.
To configure an sFlow device, using SNMP commands, to send sFlow data to Flow
Monitor:
Important: This procedure is an example that applies to an HP ProCurve 2610 switch and
should not be used for other devices. The process for configuring a device to export sFlow
data varies widely from device to device and is dependent upon your network configuration.
Refer to the documentation to determine the correct process for your device.
Important: An sFlow device configured with the SNMP commands typically do not save the 976
configuration to memory. If the device is rebooted, or power is lost, all sFlow configuration is
lost and must be manually reset using the SNMP commands. Make sure that you save the
SNMP configuration commands for future device configuration.
