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

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.
