Concept Guide

System accounting can use only the default method list.
Example of Conguring AAA Accounting to Track EXEC and EXEC Privilege Level Command Use
In the following sample conguration, AAA accounting is set to track all usage of EXEC commands and commands on privilege level 15.
DellEMC(conf)#aaa accounting exec default start-stop tacacs+
DellEMC(conf)#aaa accounting command 15 default start-stop tacacs+
Conguring AAA Accounting for Terminal Lines
To enable AAA accounting with a named method list for a specic terminal line (where com15 and execAcct are the method list names),
use the following commands.
• Congure AAA accounting for terminal lines.
CONFIG-LINE-VTY mode
accounting commands 15 com15
accounting exec execAcct
Example of Enabling AAA Accounting with a Named Method List
DellEMC(config-line-vty)# accounting commands 15 com15
DellEMC(config-line-vty)# accounting exec execAcct
Monitoring AAA Accounting
Dell EMC Networking OS does not support periodic interim accounting because the periodic command can cause heavy congestion
when many users are logged in to the network.
No specic show command exists for TACACS+ accounting.
To obtain accounting records displaying information about users currently logged in, use the following command.
• Step through all active sessions and print all the accounting records for the actively accounted functions.
CONFIGURATION mode or EXEC Privilege mode
show accounting
Example of the show accounting Command for AAA Accounting
DellEMC#show accounting
Active accounted actions on tty2, User admin Priv 1
Task ID 1, EXEC Accounting record, 00:00:39 Elapsed, service=shell
Active accounted actions on tty3, User admin Priv 1
Task ID 2, EXEC Accounting record, 00:00:26 Elapsed, service=shell

RADIUS Accounting
Dell EMC Networking OS supports Remote Authentication Dial In User Service (RADIUS) protocol to transmit the RADIUS accounting
messages between a Network Access Server (NAS) and an accounting server.
NAS reports the user activity to the accounting server (RADIUS or TACACS+) with accounting records. The RADIUS accounting server
stores the accounting records, which is used for network management, auditing, etc.
Dell EMC Networking OS complies with RFC2866 for RADIUS Accounting.
