Chapter 49 Configuring 802.1X Port-Based Authentication
Controlling Switch Access with RADIUS
To disable AAA, use the
no aaa new-model
global configuration command. To disable AAA authentication, use the
no aaa
authentication login
{
default
|
list-name
}
method1
[
method2...
] global 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.
Note
To secure the switch for HTTP access by using AAA methods, you must configure the switch with the
ip http authentication aaa
global configuration command. Configuring AAA authentication does not
secure the switch for HTTP access by using AAA methods.
For more information about the
ip http authentication
command, see the

Defining AAA Server Groups
You can configure the switch 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, (for
example, 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.
