Introduction
The SolarWinds NetFlow Configurator provides a simple, wizard-driven tool
to remotely configure your NetFlow-capable Cisco routers. At this time,
support for version 5 of NetFlow is provided.
Configuring Your NetFlow-Enabled Devices
Complete the following procedure to configure your NetFlow-enabled devices to send flow data to Real-time NetFlow Analyzer.
Notes:
- NetFlow Configurator uses SNMP to change the running config of the
NetFlow-capable device. If your device cannot be updated using SNMP,
or it does not support the OID 1.3.6.1.4.1.9.9.387.1.2.1.1, then NetFlow
Configurator cannot update the NetFlow configuration of the device.
-
The following Cisco IOS versions support the configuration of NetFlow using SNMP:
- 12.4(10) or later
- 12.4(10)T or later
- 12.2S or later
To configure your NetFlow-capable Cisco router:
- Click Start > All Programs > SolarWinds NetFlow Configurator > NetFlow Configurator.
- Specify the hostname or IP address of the NetFlow device you want to configure.
- Select the version of SNMP you want to use when communicating with this device.
Note: The community string or SNMP version 3 credentials you
provide must have read-write access to the device.
- Click the Next.
- Ensure the Device Info section of the window provides the appropriate
device information. That is, ensure you are modifying the correct device.
- Specify the appropriate information in the Device NetFlow Configuration
section of the window, and then click Apply.
- Provide the IP addresses and ports of the host you want the device
to target with exported NetFlow data in the Export to host fields.
NetFlow data can be exported to 2 different collection points.
- Select the ingress (incoming relative to the device) and egress
(outgoing relative to the device) interface traffic you want to monitor.
If you are using the NetFlow Configurator to setup NetFlow on a
router for use with Orion NetFlow Traffic Analyzer, only the ingress
traffic should be monitored.
Note: All information about all NetFlow data flowing through the device is
exported to the specified hosts. Exported data is not confined to traffic
generated or received on specific interfaces.
- If you want to configure another router or switch, click Configure
another device. Otherwise, click Exit.
Using Real-time NetFlow Analyzer
Use the SolarWinds Real-time NetFlow Analyzer to capture and view your NetFlow Data.
