Example: Configuring Flow Monitoring
The following is an example of flow-monitoring
properties configured to support input SONET/SDH interfaces, output
monitoring services interfaces, and export to cflowd for flow analysis.
To complete the configuration, you also need to configure the interfaces
and set up a virtual private network (VPN) routing and forwarding
(VRF) instance. For a complete example, see the JUNOS Feature Guide.
For information on cflowd, see Configuring Flow Aggregation.
