Controlling Access Point Access with RADIUS
To disable AAA, use the
no aaa new-model
command in global command mode. To disable AAA
authentication, use the
no aaa authentication login
{
default
|
list-name
}
method1
[
method2...
]
command in global command mode. To either disable RADIUS authentication for logins or to return to
the default value, use the
no login authentication
{
default
|
list-name
} command in line configuration
mode.
Defining AAA Server Groups
You can configure the wireless device to use AAA server groups to group existing server hosts for
authentication. You select a subset of the configured server hosts and use them for a particular service.
The server group is used with a global server-host list, which lists the IP addresses of the selected server
hosts.
Server groups can also include multiple host entries for the same server if each entry has a unique
identifier (the combination of the IP address and UDP port number), allowing different ports to be
individually defined as RADIUS hosts providing a specific AAA service. If you configure two different
host entries on the same RADIUS server for the same service (such as accounting), the second
configured host entry acts as a failover backup to the first one.
You use the
server
group server configuration command to associate a particular server with a defined
group server. You can either identify the server by its IP address or identify multiple host instances or
entries by using the optional
auth-port
and
acct-port
keywords.
To define the AAA server group and associate a particular RADIUS server with it, follow these steps,
beginning in privileged EXEC mode.

}
Applies the authentication list to a line or set of lines.
•
If you specify
default
, use the default list that you created with the
aaa authentication login
command.
•
For
list-name
, specify the list that you created with the
aaa
authentication login
command.
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.
