Chapter 6 Configuring IEEE 802.1x Port-Based Authentication
Configuring IEEE 802.1x Authentication
To disable AAA, use the no aaa new-model global configuration command. To disable IEEE 802.1x
AAA authentication, use the no aaa authentication dot1x {default | list-name} global configuration
command. To disable IEEE 802.1x AAA authorization, use the no aaa authorization global
configuration command. To disable IEEE 802.1x authentication on the switch, use the no dot1x
system-auth-control global configuration command.
This example shows how to enable AAA and IEEE 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 gigabitethernet0/17
Switch(config-if)# switchport mode access
Switch(config-if)# dot1x port-control auto
Switch(config-if)# end
Configuring the Switch-to-RADIUS-Server Communication
RADIUS security servers are identified by their host name or IP address, host name and specific UDP
port numbers, or IP address and specific UDP port numbers. The combination of the IP address and UDP
port number creates a unique identifier, which enables RADIUS requests to be sent to multiple UDP
ports on a server at the same IP address. If two different host entries on the same RADIUS server are
configured for the same service—for example, authentication—the second host entry configured acts as
the fail-over backup to the first one. The RADIUS host entries are tried in the order that they were
configured.
Step 9
swtichport mode access
(Optional) Set the port to access mode only if you configured the RADIUS
server in Step 6 and Step 7.
Step 10
dot1x port-control auto
Enable IEEE 802.1x authentication on the interface.
For feature interaction information, see the
Guidelines” section on page 6-12
Step 11
end
Return to privileged EXEC mode.
Step 12
show dot1x
Verify your entries.
Check the Status column in the IEEE 802.1x Port Summary section of the
display. An enabled status means the port-control value is set either to
auto or to force-unauthorized.
Step 13
copy running-config startup-config
(Optional) Save your entries in the configuration file.
