Chapter 9 Configuring Switch-Based Authentication

Controlling Switch Access with RADIUS

Starting TACACS+ 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 TACACS+ 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 TACACS+ accounting for each Cisco IOS privilege level and for network services:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	aaa accounting network start-stop	Enable TACACS+ accounting for all network-related service requests.
	tacacs+
Step 3
	aaa accounting exec start-stop tacacs+	Enable TACACS+ accounting to send a start-record accounting notice at
		the beginning of a privileged EXEC process and a stop-record at the end.
Step 4
	end	Return to privileged EXEC mode.
Step 5
	show running-config	Verify your entries.
Step 6
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

To disable accounting, use the no aaa accounting {network exec} {start-stop} method1... global configuration command.

Displaying the TACACS+ Configuration

To display TACACS+ 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.
