Prerequisites

Before setting up NetFlow Analyzer in your enterprise, ensure that the following are taken care of.

Ports Required

NetFlow Analyzer requires the following ports to be free:

Port Name	Default Port Number	Usage
Web server port	8080	This is the port on which you will connect to the NetFlow Analyzer server from a web browser. You can change this at any time from the Settings tab.
NetFlow Listener port	9996	This is the port on which NetFlow exports are received from routers. You can change this at any time from the Settings tab.
MySQL port	13310	This is the port used to connect to the MySQL database in NetFlow Analyzer. Changing this port requires configuration level changes.

Apart from the System Requirements, the following setup would ensure optimal performance from NetFlow Analyzer.

Run NetFlow Analyzer on a separate, dedicated PC or server. The software is resource-intensive, and a busy processor can cause problems in collecting NetFlow data.
Use the MySQL pre-bundled with NetFlow Analyzer that runs on port 13310. You need not start another separate instance of MySQL.

Edit the mysql-ds.xml file present in the <NetFlowAnalyzer_Home>/server/default/deploy directory.
Change the port number in the following line to the desired port number:
<connection-url>jdbc:mysql://localhost:13310/netflow</connection-url>
Save the file and restart the server.
