Chapter 11 Configuring Switch-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 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.
