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.

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 Cisco IOS Security Command

Reference, Release 12.2.

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.
