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
comprises accounting attribute/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.
