Controlling Switch Access with RADIUS
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:
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:
Step 4
Switch(config)# end
Returns to privileged EXEC mode.
Step 5
Switch# show running-config
Verifies your entries.
Step 6
Switch# copy running-config
startup-config
(Optional) Saves your entries in the configuration file.
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config)# aaa accounting
network start-stop radius
Enables RADIUS accounting for all network-related service requests.
Step 3
Switch(config)# aaa accounting exec
start-stop radius
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.
Step 4
Switch(config)# end
Returns to privileged EXEC mode.
Step 5
Switch# show running-config
Verifies your entries.
Step 6
Switch# copy running-config
startup-config
(Optional) Saves your entries in the configuration file.
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config)# radius-server key
string
Specifies the shared secret text string used between the switch and all
RADIUS servers.
Note The key is a text string that must match the encryption key used on
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.
Step 3
Switch(config)# radius-server
retransmit retries
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.
