Chapter 8 Configuring Switch-Based Authentication
Controlling Switch Access with RADIUS
Beginning in privileged EXEC mode, follow these steps to specify RADIUS authorization for privileged
EXEC access and network services:
To disable authorization, use the no aaa authorization {network | exec} method1 global configuration
command.
Starting RADIUS 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 RADIUS 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 RADIUS 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.
