Enabling AAA Accounting
The aaa accounting command allows you to create a record for any or all of the accounting functions
monitored.
To enable AAA accounting, use the following command.
• Enable AAA accounting and create a record for monitoring the accounting function.
CONFIGURATION mode
aaa accounting {commands | exec | suppress | system level} {default | name}
{start-stop | wait-start | stop-only} {tacacs+}
The variables are:
• system: sends accounting information of any other AAA configuration.
• exec: sends accounting information when a user has logged in to EXEC mode.
• command level: sends accounting of commands executed at the specified privilege level.
• suppress: Do not generate accounting records for a specific type of user.
• default | name: enter the name of a list of accounting methods.
• start-stop: use for more accounting information, to send a start-accounting notice at the
beginning of the requested event and a stop-accounting notice at the end.
• wait-start: ensures that the TACACS+ security server acknowledges the start notice before
granting the user's process request.
• stop-only: use for minimal accounting; instructs the TACACS+ server to send a stop record
accounting notice at the end of the requested user process.
• tacacs+: designate the security service. Currently, Dell Networking OS supports only TACACS+.
Suppressing AAA Accounting for Null Username Sessions
When you activate AAA accounting, the Dell Networking OS software issues accounting records for all users
on the system, including users whose username string is NULL because of protocol translation.
An example of this is a user who comes in on a line where the AAA authentication login method-list
none
command is applied. To prevent accounting records from being generated for sessions that do not
have usernames associated with them, use the following command.
• Prevent accounting records from being generated for users whose username string is NULL.
CONFIGURATION mode
aaa accounting suppress null-username
