AAA Accounting

For details about commands related to AAA security, refer to the Security chapter in the FTOS 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.
