To direct traffic to a flow collection interface, include the flow-export-destination statement. For more information about flow collection, see Flow Collection Configuration Guidelines.
To configure the cflowd version number, include the export-format statement at the [edit forwarding-options monitoring name output] hierarchy level. By default, version 5 is used. Version 8 enables the router software to aggregate the flow information using broader criteria and reduce cflowd traffic. Version 8 aggregation is performed periodically (every few seconds) on active flows and when flows are allowed to expire. Because the aggregation is performed periodically, active timeout events are ignored.
For more information on cflowd properties, see Configuring Flow Aggregation.
