Chapter 8 Configuring IEEE 802.1x Port-Based Authentication
This is the IEEE 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 IEEE 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 interface interface-id
Step 7 dot1x port-control auto
Step 8 end
Step 9 show dot1x
Step 10

Purpose
Enter global configuration mode.
Enable AAA.
Create an IEEE 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
method that is to be used 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.
Though other keywords are visible in the command-line help
Note
string, only the group radius keywords are supported.
Enable IEEE 802.1x authentication globally on the switch.
(Optional) Configure the switch for user RADIUS authorization for all
network-related service requests, such as VLAN assignment.
Specify the port connected to the client that is to be enabled for IEEE
802.1x authentication, and enter interface configuration mode.
Enable IEEE 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.
