AAA Accounting
Accounting, authentication, and authorization (AAA) accounting is part of the AAA security model.
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 congure AAA accounting by dening a named list of accounting methods and then
applying that list to various virtual terminal line (VTY) lines.
