Cabletron’s Traffic Accounting Services
Cabletron’s Accounting Services consists of the following components:
• LFAP agent on the SSR that collects application flow accounting information and sends
it to the Cabletron FAS. You can configure the SSR to collect information on an entire
interface or on a specific host-to-host application flow. Configuring the LFAP agent on
the SSR is described in this chapter. See the SmartSwitch Router Command Line Interface
Reference Manual for details on the lfap commands.
• One or more Cabletron FAS systems. The main responsibility of Cabletron’s FAS is to
listen for LFAP messages from the SSRs on the network and collect the information. A
single FAS can collect data from multiple SSRs. See the Cabletron Accounting Installation
and Upgrade Guide for information about configuring the FAS.
• Cabletron Traffic Accountant is a database and reporting application that allows you
to create customized reports. See the Cabletron Accounting Installation and Upgrade Guide
for information about installing the Traffic Accountant; see the FAS and CTA User
Reference for information about using the Traffic Accountant.
Figure 26 shows the interactions between LFAP on the SSR, the FAS, and the Traffic
Accountant.

Configuring the LFAP Agent on the SSR
Because the FAS-to-SSR connection is via TCP, LFAP messages can be transmitted across a
LAN or a WAN. However, if you are deploying traffic accounting to save backbone or
WAN bandwidth, it makes sense to have the FAS as close as possible to the SSRs that it
manages.
Up to three FAS systems can be configured on an SSR, although the SSR can only send
LFAP messages to a single FAS at a time. The first configured FAS is the primary, so the SSR
