To disable AAA, use the no aaa new-model global configuration command. To disable 802.1x AAA
authentication, use the no aaa authentication dot1x {default | list-name} global configuration
command. To disable 802.1x AAA authorization, use the no aaa authorization global configuration
command. To disable 802.1x authentication on the switch, use the no dot1x system-auth-control global
configuration command.
This example shows how to enable AAA and 802.1x on a port:
Switch# configure terminal
Switch(config)# aaa new-model
Switch(config)# aaa authentication dot1x default group radius
Switch(config)# dot1x system-auth-control
Switch(config)# interface fastethernet1/0/1
Switch(config)# switchport mode access
Switch(config-if)# dot1x port-control auto
Switch(config-if)# end

Purpose
Enter global configuration mode.
Enable AAA.
Create an 802.1x authentication method list.
To create a default list that is used when a named list is not specified in
the authentication command, use the default keyword followed by the
methods that are to be used in default situations. The default method list
is automatically applied to all ports.
Enter at least one of these keywords:
• group radius—Use the list of all RADIUS servers for authentication.
none—Use no authentication. The client is automatically
•
authenticated by the switch without using the information supplied by
the client.
Enable 802.1x authentication globally on the switch.
(Optional) Configure the switch for user RADIUS authorization for all
network-related service requests, such as per-user ACLs or VLAN
assignment.
For per-user ACLs, single-host mode must be configured. This
Note
setting is the default.
Specify the port connected to the client that is to be enabled for 802.1x
authentication, and enter interface configuration mode.
Enable 802.1x authentication on the port.
For feature interaction information, see the
Guidelines" section on page
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
