aaa accounting

To enable authentication, authorization, and accounting (AAA) accounting of requested services for billing or security purposes when you use RADIUS or TACACS+, use the aaa accounting command in global configuration mode or template configuration mode. To disable AAA accounting, use the no form of this command.

aaa accounting {auth-proxy | system | network | exec | connection | commands level | dot1x} {default | list-name | guarantee-first} [vrf vrf-name] {start-stop | stop-only | none} [broadcast] {radius | group group-name} no aaa accounting {auth-proxy | system | network | exec | connection | commands level | dot1x} {default | listname | guarantee-first} [vrf vrf-name] {start-stop | stop-only | none} [broadcast] {radius | group group-name} exec

Runs accounting for the EXEC shell session.

start-stop

Sends a "start" accounting notice at the beginning of a process and a "stop" accounting notice at the end of a process. The "start" accounting record is sent in the background. The requested user process begins regardless of whether the "start" accounting notice was received by the accounting server.
