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.
Beginning in privileged EXEC mode, follow these steps to enable RADIUS accounting for each Cisco
IOS privilege level and for network services:
Command
Step 1
configure terminal
Step 2
aaa accounting network start-stop
radius
Step 3
aaa accounting exec start-stop radius
Step 4
end
Step 5
show running-config
Step 6
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
Beginning in privileged EXEC mode, follow these steps to configure global communication settings
between the switch and all RADIUS servers:
Command
Step 1
configure terminal
Step 2
radius-server key string
Step 3
radius-server retransmit retries
Step 4
radius-server timeout seconds

Purpose
Enter global configuration mode.
Enable RADIUS accounting for all network-related service requests.
Enable RADIUS 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.
Purpose
Enter global configuration mode.
Specify 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.
Specify 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.
Specify the number of seconds a switch waits for a reply to a RADIUS
request before resending the request. The default is 5 seconds; the range is
1 to 1000.
