AAA Accounting Commands
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 TACACS+ security server in the form of
accounting records. Each accounting record is comprised of accounting 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 interfaces.
aaa accounting
Enable AAA Accounting and create a record for monitoring the accounting function.
Syntax
aaa accounting {system | exec | commands level} {name | default}{start-stop |
wait-start | stop-only} {tacacs+}
To disable AAA Accounting, use the no aaa accounting {system | exec | command level}
{name | default}{start-stop | wait-start | stop-only} {tacacs+} command.
