Configuring and Enabling RADIUS
To disable AAA, use the
no aaa new-model
global configuration command. To disable AAA
authentication, use the
no aaa authentication login

configuration command. To either disable RADIUS authentication for logins or to return to the default
value, use the
no login authentication
{
default
|
list-name
} line configuration command.
Defining AAA Server Groups
You can configure the access point 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 also can 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 fail-over 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.
Beginning in privileged EXEC mode, follow these steps to define the AAA server group and associate a
particular RADIUS server with it:
