29 LFAP CONFIGURATION GUIDE
29.1 OVERVIEW
The Lightweight Flow Accounting Protocol (LFAP) agent, as originally defined in RFC 2124, is a TCP-oriented
protocol used to push accounting information collected on the RS to a flow accounting server. The LFAP agent
uses ACLs to determine the IP traffic on which accounting information will be collected.
Traffic accounting in the network can help with the following:
• Capacity planning
• Application usage tracking
• Cost apportioning by user or department
• Server and resource usage
Traffic accounting is not intended for troubleshooting immediate network problems, enforcing company policies,
or replacing the accounts payable system.
Note For a complete list of LFAP related commands, see the Riverstone RS Switch
Router Command Line Interface Reference Manual.
29.2 REQUIREMENTS
• LFAP agent — Available on RS switch routers
• Server that understands LFAP (a simple server can be downloaded from www.nmops.org)
29.3 TRAFFIC ACCOUNTING SERVICES
Riverstone’s Accounting Services consists of the following components:
• LFAP agent on the RS that collects application flow accounting information and sends it to the
Riverstone accounting server. You can configure the RS to collect information on an entire
interface or on a specific host-to-host application flow. Configuring the LFAP agent on the RS
is described in this chapter.
