Chapter 8 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: Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Command configure terminal aaa accounting network start-stop tacacs+ aaa accounting exec start-stop tacacs+ end show running-config copy running-config startup-config Purpose Enter global configuration mode. Enable TACACS+ accounting for all network-related service requests. 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. Return to privileged EXEC mode. Verify your entries. (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 from the Cisco.com page under Documentation > Cisco IOS Software > 12.2 Mainline > Command References.
