Chapter 12 Configuring IEEE 802.1x Port-Based Authentication
This is the 802.1x AAA process:
A user connects to a port on the switch.
Step 1
Authentication is performed.
Step 2
VLAN assignment is enabled, as appropriate, based on the RADIUS server configuration.
Step 3
Step 4 The switch sends a start message to an accounting server.
Step 5 Re-authentication is performed, as necessary.
Step 6 The switch sends an interim accounting update to the accounting server, that is based on the result of
re-authentication.
Step 7 The user disconnects from the port.
Step 8 The switch sends a stop message to the accounting server.
Beginning in privileged EXEC mode, follow these steps to configure 802.1x port-based authentication:
Command
Step 1
configure terminal
Step 2 aaa new-model
Step 3 aaa authentication dot1x {default}
method1
Step 4
dot1x system-auth-control
Step 5 aaa authorization network {default}
group radius
Step 6 radius-server host ip-address
Step 7 radius-server key string
Step 8 interface interface-id
Step 9
switchport mode access
Step 10
authentication port-control auto
or
dot1x port-control auto
Step 11 end

Purpose
Enter global configuration mode.
Enable AAA.
Create an 802.1x authentication method list.
To create a default list to use when a named list is not specified in the
authentication command, use the default keyword followed by the
method to use in default situations. The default method list is
automatically applied to all ports.
For method1, enter the group radius keywords to use the list of all
RADIUS servers for authentication.
Note Though other keywords are visible in the command-line help
string, only the group radius keywords are supported.
Enable 802.1x authentication globally on the switch.
(Optional) Configure the switch to use user-RADIUS authorization for all
network-related service requests, such as VLAN assignment.
(Optional) Specify the IP address of the RADIUS server.
(Optional) Specify the authentication and encryption key used between
the switch and the RADIUS daemon running on the RADIUS server.
Specify the port connected to the client to enable for 802.1x
authentication, and enter interface configuration mode.
(Optional) Set the port to access mode only if you configured the RADIUS
server in Step 6 and Step 7.
Enable 802.1x authentication on the port.

Configuration Guidelines" section on page
Return to privileged EXEC mode.
