Configure Flow Monitor to listen for NetFlow data

Use the Listener port settings on the Flow Settings to configure Flow Monitor to listen for NetFlow data. You can enter the TCP/IP port numbers which the Flow Monitor collector service should use to listen for flow information in the Listener port box. Flow Monitor can listen on one or more ports, with port 9999 being the default. The sources sending flow information to Flow Monitor must send data using one of these ports.

Note: If you configure Flow Monitor to listen on more than one port or on a port other than the default port, you should verify that the port is not being used by another service and ensure that an exception is added to the firewall if you are using Windows Firewall.

To configure Flow Monitor to listen for NetFlow data:

Note: By default, Flow Monitor listens for Flow data on port 9999. If you want to use that port, you do not need to perform this procedure.

  1. Navigate to the Flow Settings dialog (Flow Monitor > Settings). The Flow Settings dialog appears.
  2. In Listener port, enter the port numbers, separated by commas, over which Flow Monitor should listen for Flow data.

Click OK to save the changes.
