Configuring ATM Accounting
ATM Accounting Overview
The ATM accounting feature provides accounting and billing services for virtual circuits (VCs) used on
the ATM switch router. You enable ATM accounting on an edge switch to monitor call setup and traffic
activity. A specific interface can be configured to monitor either incoming or outgoing or incoming and
outgoing VC use. Figure 15-1 shows a typical ATM accounting environment.
Figure15-1 ATM Accounting Environment
The edge switches, connected to the exterior Internet, are connections that require monitoring for
accounting and billing purposes.
Switching speeds and number of VCs supported by the ATM switch router while monitoring virtual
circuit use for accounting purposes can cause the am ount of data to be gathered to reach the megabyte
range. With such a large amount of data in the ATM accounting files, using traditional Simple Network
Management Protocol (SNMP) methods of data retrieval is not feasible. You can store the collected
accounting information in a file that you can retrieve using a file transfer protocol. SNMP provides
management control of the selection and collection of accounting data. Figure 15-2 shows an interface,
filtering, and file configuration example.
