Configuring IEEE 802.1x Authentication
This example shows how to enable VLAN 2 as an IEEE 802.1x guest VLAN:
Switch(config)# interface gigabitethernet0/2
Switch(config-if)# dot1x guest-vlan 2
This example shows how to set 3 as the quiet time on the switch, to set 15 as the number of seconds that
the switch waits for a response to an EAP-request/identity frame from the client before re-sending the
request, and to enable VLAN 2 as an IEEE 802.1x guest VLAN when an IEEE 802.1x port is connected
to a DHCP client:
Switch(config-if)# dot1x timeout quiet-period 3
Switch(config-if)# dot1x timeout tx-period 15
Switch(config-if)# dot1x guest-vlan 2
Configuring a Restricted VLAN
When you configure a restricted VLAN on a switch, clients that are IEEE 802.1x-compliant are moved
into the restricted VLAN when the authentication server does not receive a valid username and
password. The switch supports restricted VLANs only in single-host mode.
Beginning in privileged EXEC mode, follow these steps to configure a restricted VLAN. This procedure
is optional.
Command
Step 1
configure terminal
Step 2
interface interface-id
Step 3
switchport mode access
or
switchport mode private-vlan host
Step 4
dot1x port-control auto
Step 5
dot1x auth-fail vlan vlan-id
Step 6
end
Step 7
show dot1x interface interface-id
Step 8
copy running-config startup-config
To disable and remove the restricted VLAN, use the no dot1x auth-fail vlan interface configuration
command. The port returns to the unauthorized state.
This example shows how to enable VLAN 2 as an IEEE 802.1x restricted VLAN:
Switch(config)# interface gigabitethernet0/2
Switch(config-if)# dot1x auth-fail vlan 2

Purpose
Enter global configuration mode.
Specify the port to be configured, and enter interface configuration mode.
For the supported port types, see the
Configuration Guidelines" section on page
Set the port to access mode,
or
Configure the Layer 2 port as a private-VLAN host port.
Enable IEEE 802.1x authentication on the port.
Specify an active VLAN as an IEEE 802.1x restricted VLAN. The range
is 1 to 4094.
You can configure any active VLAN except an internal VLAN (routed
port), an RSPAN VLAN, a primary private VLAN, or a voice VLAN as
an IEEE 802.1x restricted VLAN.
Return to privileged EXEC mode.
(Optional) Verify your entries.
(Optional) Save your entries in the configuration file.
