[Device] dot1x port-method macbased interface gigabitethernet 1/0/1
Verifying the configuration
Use the display dot1x interface gigabitethernet 1/0/1 command to verify the 802.1X configuration.
After an 802.1X user passes RADIUS authentication, you can use the display connection command to
view information about the user connection. If the user fails RADIUS authentication, local authentication
is performed.
802.1X with guest VLAN and VLAN assignment configuration
example
Network requirements
As shown in Figure 32:
• A host is connected to port GigabitEthernet 1/0/2 of the device and must pass 802.1X
authentication to access the Internet. GigabitEthernet 1/0/2 is in VLAN 1.
• GigabitEthernet 1/0/2 implements port-based access control.
• GigabitEthernet 1/0/3 is in VLAN 5 and is for accessing the Internet.
• The authentication server runs RADIUS and is in VLAN 2.
• The update server in VLAN 10 is for client software download and upgrade.
• If no user passes 802.1X authentication on GigabitEthernet 1/0/2 within a period of time (90
seconds by default), the device adds GigabitEthernet 1/0/2 to its guest VLAN, VLAN 10. The host
and the update server are both in VLAN 10 and the host can access the update server and
download the 802.1X client software.
• After the host passes 802.1X authentication, the host is assigned to VLAN 5 where GigabitEthernet
1/0/3 is. The host can access the Internet.
