Chapter Administering the Wireless Device
Controlling Access Point Access with RADIUS
To remove the specified RADIUS server, use the
no radius-server host
hostname
|
ip-address
command
in global configuration mode. To remove a server group from the configuration list, use the
no aaa group
server radius
group-name
command in global configuration mode. To remove the IP address of a
RADIUS server, use the
no server
ip-address
command in sg-radius configuration mode.
In the following is example, the wireless device is configured to recognize two different RADIUS group
servers (
group1
and
group2
). Group1 has two different host entries on the same RADIUS server which
are configured for the same services. The second host entry acts as a failover backup to the first entry.
AP(config)#
aaa new-model
AP(config)#
radius-server host 172.20.0.1 auth-port 1000 acct-port 1001
AP(config)#
radius-server host 172.10.0.1 auth-port 1645 acct-port 1646
AP(config)#
aaa group server radius group1
AP(config-sg-radius)#
server 172.20.0.1 auth-port 1000 acct-port 1001
AP(config-sg-radius)#
exit
AP(config)#
aaa group server radius group2
AP(config-sg-radius)#
server 172.20.0.1 auth-port 2000 acct-port 2001
AP(config-sg-radius)#
exit
Configuring RADIUS Authorization for User Privileged Access and
Network Services
AAA authorization limits the services that are available to a user. When AAA authorization is enabled,
the wireless device uses information retrieved from the user’s profile, which is in the local user database
or on the security server, to configure the user session. The user is granted access to a requested service
only if the user profile allows it.
You can use the
aaa authorization
command in global configuration mode with the
radius
keyword to
set parameters that restrict a user’s network access to privileged EXEC mode.
The
aaa authorization exec radius
command sets these authorization parameters:
•
Use RADIUS for privileged EXEC access authorization if authentication was performed by using
RADIUS.
•
Use the local database if authentication was not performed by using RADIUS.
Note
Authorization is bypassed for authenticated users who log in through the CLI even if authorization has
been configured.
Step 6
end
Returns to privileged EXEC mode.
Step 7
show running-config
Verifies your entries.
Step 8
copy running-config startup-config
(Optional) Saves your entries in the configuration file.
Step 9
aaa authorization exec radius
Enables RADIUS login authentication. See the
Login Authentication” section of the “Configuring Radius and
Servers”
