If you are adding a large number of NetFlow enabled nodes, use SolarWinds Platform Network Sonar. The documentation of your network deviceĪdd the device exporting NetFlow to SolarWinds NPM for monitoring.Otherwise, consult these examples as apply to your device:.For information on enabling NetFlow on Cisco ASA devices, see Cisco ASA NetFlow overview.For information on enabling NetFlow for Cisco Catalyst switches, see Enable NetFlow and NetFlow data export on Cisco Catalyst switches.For detailed information on configuring NetFlow on Cisco devices, search for the appropriate configuration in the Cisco NetFlow Configuration guide (© 2021 Cisco, available at, obtained on May 6th, 2021).

The following example enables NetFlow on a Cisco 6500 Series device:

Enable NetFlow export on the device using appropriate commands.

Set up a device to export NetFlow data to SolarWinds NTA The interface index number for this interface in the SolarWinds Platform database (interface table) must match the index number in the collected flow data.

The specific interface through which a device exports NetFlow data must be monitored in SolarWinds NPM.

If the device is setup to export data to SolarWinds NTA, but is unmonitored in SolarWinds NPM, the collector may receive the data without being able to meaningfully analyze it.

Traffic from a device that is not monitored in SolarWinds NPM appears only in aggregate as traffic from unmonitored devices.

Only nodes whose interfaces were discovered by SolarWinds NPM can be added as NetFlow sources.

Each device that exports NetFlow data to SolarWinds NTA must be monitored in SolarWinds NPM.

Each device must be configured to export NetFlow data to SolarWinds NTA.Once it collects NetFlow traffic data, SolarWinds NTA analyzes device bandwidth usage in terms of the source and destination endpoints of conversations reflected in the traffic. As a NetFlow collector, SolarWinds NTA can receive exported NetFlow version 5 data and NetFlow version 9 data that includes all fields of the NetFlow version 5 template. SolarWinds NTA collects NetFlow data, on port 2055 by default, only if a network device is specifically configured to send data to NTA. You must configure your device to send flow data to SolarWinds NTA. Set up network devices to export NetFlow data
