AAA Accounting

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 congure AAA accounting by dening a named list of accounting methods and
then applying that list to various virtual terminal line (VTY) lines.
