Chapter 8 Configuring Switch-Based Authentication
Controlling Switch Access with RADIUS
Starting Accounting
The AAA accounting feature tracks the services that users are accessing and the amount of network
resources that they are consuming. When AAA accounting is enabled, the switch reports user activity to
the security server in the form of accounting records. Each accounting record contains
accounting attribute-value (AV) pairs and is stored on the security server. This data can then be analyzed
for network management, client billing, or auditing.
Beginning in privileged EXEC mode, follow these steps to enable accounting for each Cisco
IOS privilege level and for network services:
To disable accounting, use the no aaa accounting { network | exec } { start-stop } method1... global
configuration command.
Displaying the Configuration
To display server statistics, use the show tacacs privileged EXEC command.
Controlling Switch Access with RADIUS
This section describes how to enable and configure the RADIUS, which provides detailed accounting
information and flexible administrative control over authentication and authorization processes.
RADIUS is facilitated through AAA and can be enabled only through AAA commands.
Note For complete syntax and usage information for the commands used in this section, see the Cisco IOS
Security Command Reference, Release 12.2 .
