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.
The collector includes the following features:
■ Raw events
■ Sensor statistics
■ Importing and exporting of sensor settings, and filtering and aggregation rules
■ Global updating of sensor settings
For more information, see the Creating collector configurations section located in the Symantec Event Collectors Integration Guide.
