Overriding Default Parameters
482 Enterasys X-Pedition User Reference Manual
NetFlow commands set configuration parameters and display data. Configuration commands
establish NetFlow internal task parameters and define the XP/collector relationship. The commands
used in the following example are required to set up accounting and exportation. These commands
specify the ports whose flows will be accounted, identify the collector used to receive exported
data, and activate the NetFlow feature. In this example, accounting and data exportation occur for
the flows on all the Ethernet ports in slot 1—there is only one collector selected to receive the
accounting data (134.141.135.124). The collector application communicates on the default port,
2055. All other system defaults apply, including the 30-minute export interval.

Overriding Default Parameters
Export Interval
By default, the XP initializes the default export interval to 30 minutes. When setting the export
interval, select an interval according to the type of application used. To set the interval (from
1 to 1440 minutes—24 hours), enter the following:
System Memory Utilization
The NetFlow client acquires memory as needed from the system heap to store flow information
entries. Unless otherwise specified by the netflow set memory command, the system reserves
450 kilobytes of memory by default. If the volume of flows exceeds the memory limit, new flows
are not stored and flow information is lost (if the XP begins to discard flows, an error message will
