Configure Accounting of EXEC and privilege-level command usage

(AV) pairs.
In the following sample configuration, AAA accounting is set to track all usage of EXEC commands and
commands on privilege level 15.
System accounting can use only the default method list:
aaa accounting system default start-stop tacacs+
Configure AAA Accounting for terminal lines
Use the following commands to enable accounting with a named method list for a specific terminal line
(where com15 and execAcct are the method list names):

information about users currently logged in, perform the following task in Privileged EXEC mode:
