How do I enable NetFlow on SolarWinds?
How do I enable NetFlow on SolarWinds?
Set up a device to export NetFlow data to SolarWinds NTA
- Log in to the network device.
- Add the device exporting NetFlow to SolarWinds NPM for monitoring.
- Verify that the device is exporting NetFlow data as expected and that the device is monitored in SolarWinds NPM.
- Click My Dashboards > NetFlow > NTA Summary.
How do I enable NetFlow on ASA?
In ASDM under Configuration go in Device Management > Logging > Netflow.
- There you can set the Netflow collector ip address, the ASA interface it is behind and the port it supports.
- You create a new service policy that needs to be applied GLOBALLY.
- Define the traffic that you need to collect Netflow statistics for.
What is NetFlow in Asa?
NetFlow on the ASA provides an efficient way to track connection creation, teardown and denies in an efficient manner. This is done by sending binary data in UDP packets as opposed to ASCII based syslog messages.
What port does SolarWinds NetFlow use?
port 2055
By default, SolarWinds NTA listens for flow data on port 2055, but some flow-enabled devices, including some Nortel IPFIX-enabled devices, send flow data on port 9995.
What ports need to be open for SolarWinds?
Orion Agents: target computer
| Port | Protocol | Service/ Process |

| 445 | TCP | Agent installer |
| 17778 | TCP | SolarWinds Agent |
| 17790 | TCP | SolarWinds Agent |
What is the difference between Asa and SolarWinds NTA?
The ASA device is the NetFlow exporter. SolarWinds NTA is the NetFlow collector. A flow template is exported by the NetFlow exporter and sent to the NetFlow collector. Templates are used as parsers by the collector to define fields in the flow data exports.
What versions of NetFlow are supported by Asa devices?
ASA devices began supporting NetFlow as of ASA software version 8.1 (2), but there were several issues with that release. Version 8.2 (2) and later releases provide a more robust NetFlow implementation. This paper aims to provide guidance and insight for the implementation, interpretation, and troubleshooting of NetFlow on ASA appliances.
Where do I find the port used for NetFlow traffic?
The port used for NetFlow traffic is specified in the configuration of your flow‑enabled Cisco appliance. The following excerpts from a Cisco router configuration file offer an example of where to look to enable NetFlow traffic on a Cisco router:
