For details about commands related to AAA security, refer to the Security chapter in the Dell Networking OS Command Reference Guide. AAA accounting enables tracking of services that users are accessing and the amount of network resources being consumed by those services. When you enable AAA accounting, the network server reports user activity to the security server in the form of accounting records. Each accounting record is comprised of accounting atribute/value (AV) pairs and is stored on the access control server. As with authentication and authorization, you must configure AAA accounting by defining a named list of accounting methods and then applying that list to various virtual terminal line (VTY) lines. Configuration Task List for AAA Accounting The following sections present the AAA accounting configuration tasks. • Enabling AAA Accounting (mandatory) • Suppressing AAA Accounting for Null Username Sessions (optional) • Configuring Accounting of EXEC and Privilege-Level Command Usage (optional) • Configuring AAA Accounting for Terminal Lines (optional) • Monitoring AAA Accounting (optional) Enabling AAA Accounting The aaa accounting command allows you to create a record for any or all of the accounting functions monitored.
