Chapter 8 Configuring IEEE 802.1x Port-Based Authentication
Configuring IEEE 802.1x Authentication
This example shows how to configure NAC Layer 2 IEEE 802.1x validation:
Switch#
configure terminal
Switch(config)#
interface gigabitethernet0/1
Switch(config-if)#
dot1x reauthentication
Switch(config-if)#
dot1x timeout reauth-period server
Configuring Web Authentication
Beginning in privileged EXEC mode, follow these steps to configure authentication, authorization,
accounting (AAA) and RADIUS on a switch before configuring web authentication. The steps enable
AAA by using RADIUS authentication and enable device tracking.
Step 5
dot1x timeout reauth-period
{
seconds
|
server
}
Set the number of seconds between re-authentication attempts.
The keywords have these meanings:
•
seconds
—Sets the number of seconds from 1 to 65535; the default is
3600 seconds.
•
server
—Sets the number of seconds based on the value of the
Session-Timeout RADIUS attribute (Attribute[27]) and the
Termination-Action RADIUS attribute (Attribute [29]).
This command affects the behavior of the switch only if periodic
re-authentication is enabled.
Step 6
end
Return to privileged EXEC mode.
Step 7
show dot1x interface
interface-id
Verify your IEEE 802.1x authentication configuration.
Step 8
copy running-config startup-config
(Optional) Save your entries in the configuration file.
Command
Purpose
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
aaa new-model
Enable AAA.
Step 3
aaa authentication login default group
radius
Use RADIUS authentication. Before you can use this authentication
method, you must configure the RADIUS server. For more
information, see
Chapter 7, “Configuring Switch-Based
Authentication.”
The console prompts you for a username and password on future
attempts to access the switch console after entering the
aaa
authentication login
command. If you do not want to be prompted for
a username and password, configure a second login authentication
list:
Switch#
config t
Switch(config)#
aaa authentication login line-console none
Switch(config)#
line console 0
Switch(config-line)#
login authentication line-console
Switch(config-line)#
end
Step 4
aaa authorization auth-proxy default
group radius
Use RADIUS for authentication-proxy (auth-proxy) authorization.
