13 Introducing Symantec Event Collector for Cisco NetFlow Preinstallation requirements for the Cisco NetFlow Event Collector 13 Preinstallation requirements for the Cisco NetFlow Event Collector There are no preinstallation requirements. Configuring your security product to work with the collector After you have installed the necessary collector components, you must configure Cisco NetFlow so that event information is available to the collector. For detailed information on configuring Cisco NetFlow, see your security product documentation. Configuring Cisco NetFlow to work with the collector In order for the collector to harvest events, Cisco NetFlow must be enabled on the router. The port number that is configured on the router for flow export will be specified in the port number field when configuring the collector sensor. About the installation sequence The collector installation sequence is generally as follows: Register the collector Note: The SSIM Client console should be closed before registering the collector. Install the Agent Install the collector component For more information, see the Symantec Event Collectors Integration Guide. Sensor configuration The collector uses a sensor that must be configured to receive security events. After the sensor is configured, the settings must be distributed to the collectors on the target computers. The collector can not use the configuration named Default. You must create a new one.
