Chapter 9 Configuring IEEE 802.1x Port-Based Authentication
Configuring IEEE 802.1x Authentication
To return to the default value, use the no dot1x auth-fail max-attempts interface configuration
command.
This example shows how to set 2 as the number of authentication attempts allowed before the port moves
to the restricted VLAN:
Switch(config-if)# dot1x auth-fail max-attempts 2
Configuring IEEE 802.1x Authentication with WoL
Beginning in privileged EXEC mode, follow these steps to enable IEEE 802.1x authentication with WoL.
This procedure is optional.
To disable IEEE 802.1x authentication with WoL, use the no dot1x control-direction interface
configuration command.
This example shows how to enable IEEE 802.1x authentication with WoL and set the port as
bidirectional:
Switch(config-if)# dot1x control-direction both
Step 8
show dot1x interface interface-id (Optional) Verify your entries.
Step 9
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
interface interface-id Specify the port to be configured, and enter interface configuration mode.
For the supported port types, see the
“IEEE 802.1x Authentication
Configuration Guidelines” section on page 9-13.
Step 3
dot1x control-direction {both | in} Enable IEEE 802.1x authentication with WoL on the port, and use these
keywords to configure the port as bidirectional or unidirectional.
• both—Sets the port as bidirectional. The port cannot receive packets
from or send packets to the host. By default, the port is bidirectional.
• in—Sets the port as unidirectional. The port can send packets to the
host but cannot receive packets from the host.
Step 4
end Return to privileged EXEC mode.
Step 5
show dot1x interface interface-id Verify your entries.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.
