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.

• 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.
