Starting Radius Accounting - Cisco Catalyst 4500 Series Software Configuration Manual

Controlling Switch Access with RADIUS
Command
Step 4
Switch(config)# end
Step 5
Switch# show running-config
Step 6
Switch# copy running-config

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.
To enable RADIUS accounting for each Cisco IOS privilege level and for network services, perform these steps:
Command
Step 1
Switch# configure terminal
Step 2
Switch(config)# aaa accounting
network start-stop radius
Step 3
Switch(config)# aaa accounting exec
start-stop radius
Step 4
Switch(config)# end
Step 5
Switch# show running-config
Step 6
Switch# copy running-config
startup-config
To disable accounting, use the no aaa accounting {network | exec} {start-stop} method1... global configuration command.
Configuring Settings for All RADIUS Servers
To configure global communication settings between the switch and all RADIUS servers, perform these steps:
Command
Step 1
Switch# configure terminal
Step 2
Switch(config)# radius-server key
string
Step 3
Switch(config)# radius-server

Purpose
Returns to privileged EXEC mode.
Verifies your entries.
(Optional) Saves your entries in the configuration file.
Purpose
Enters global configuration mode.
Enables RADIUS accounting for all network-related service requests.
Enables RADIUS accounting to send a start-record accounting notice at
the beginning of a privileged EXEC process and a stop-record at the end.
Returns to privileged EXEC mode.
Verifies your entries.
(Optional) Saves your entries in the configuration file.
Purpose
Enters global configuration mode.
Specifies the shared secret text string used between the switch and all
RADIUS servers.
The key is a text string that must match the encryption key used on
Note
the RADIUS server. Leading spaces are ignored, but spaces within
and at the end of the key are used. If you use spaces in your key, do
not enclose the key in quotation marks unless the quotation marks
are part of the key.
Specifies the number of times the switch sends each RADIUS request to the
server before giving up. The default is 3; the range 1 to 1000.
