Introduction

The following information provides an example for configuring local 802.1X authentication on a wireless network.

Prerequisites

The following information applies to Comware-based access controllers and access points. Procedures and information in the examples might be slightly different depending on the software or hardware version of the access controllers and access points.

The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

The following information is provided based on the assumption that you have basic knowledge of WLAN access, WLAN user access authentication, and 802.1X authentication.

Example: Configuring local 802.1X authentication for wireless clients

Network configuration

As shown in Figure 1, the switch acts as a DHCP server to assign IP addresses to the AP and the client.

Configure the AC to meet the following requirements:

·     Perform local 802.1X authentication to control the network access of the client.

·     Use open system authentication to authenticate the client at the data link layer. This is the default authentication method.

Figure 1 Network diagram

 

Restrictions and guidelines

When you configure local 802.1X authentication for wireless clients, follow these restrictions and guidelines:

·     Use the serial ID labeled on the AP's rear panel to specify an AP.

·     Local 802.1X authentication does not support EAP relay.

Procedures

Configuring the AC

1.     Configure interfaces on the AC:

# Create VLAN 100 and VLAN-interface 100, and assign an IP address to the VLAN interface. The AC will use this IP address to establish CAPWAP control and data tunnels with the AP.

<AC> system-view

[AC] vlan 100

[AC-vlan100] quit

[AC] interface vlan-interface 100

[AC-Vlan-interface100] ip address 2.2.2.1 24

[AC-Vlan-interface100] quit

# Create VLAN 200 and VLAN-interface 200, and assign an IP address to the VLAN interface. VLAN 200 will be used for client access.

[AC] vlan 200

[AC-vlan200] quit

[AC] interface vlan-interface 200

[AC-Vlan-interface200] ip address 2.2.1.1 24

[AC-Vlan-interface200] quit

# Configure GigabitEthernet 1/0/1 (the port connected to the switch) as a trunk port, and assign the port to VLAN 100 and VLAN 200.

[AC] interface gigabitethernet 1/0/1

[AC-GigabitEthernet1/0/1] port link-type trunk

[AC-GigabitEthernet1/0/1] port trunk permit vlan 100 200

[AC-GigabitEthernet1/0/1] quit

2.     Configure a local user:

# Create a network access user named localuser and set the password to localpass in plaintext form.

[AC] local-user localuser class network

[AC-luser-network-localuser] password simple localpass

# Set the service type to lan-access.

[AC-luser-network-localuser] service-type lan-access

[AC-luser-network-localuser] quit

3.     Configure a local authentication domain:

# Create ISP domain bbb and enter its view.

[AC] domain bbb

# Configure the ISP domain to use local authentication, authorization, and accounting for LAN access wireless clients.

[AC-isp-bbb] authentication lan-access local

[AC-isp-bbb] authorization lan-access local

[AC-isp-bbb] accounting lan-access local

[AC-isp-bbb] quit

4.     Set the 802.1X authentication method to CHAP.

[AC] dot1x authentication-method chap

5.     Configure a service template:

# Create service template service and enter its view.

[AC] wlan service-template service

# Set the SSID of the service template to service.

[AC-wlan-st-service] ssid service

# Assign VLAN 200 to the matching clients.

[AC-wlan-st-service] vlan 200

# Set the user access authentication mode to 802.1X authentication.

[AC-wlan-st-service] client-security authentication-mode dot1x

# Specify ISP domain bbb for 802.1X authentication clients in the service template.

[AC-wlan-st-service] dot1x domain bbb

# Enable the AC to forward client data traffic. If the AC forwards client data traffic by default, skip this step.

[AC-wlan-st-service] client forwarding-location ac

# Enable the service template.

[AC-wlan-st-service] service-template enable

[AC-wlan-st-service] quit

6.     Configure AP settings:

 

IMPORTANT: In a large-scale network, configure AP groups as a best practice.

 

# Create manual AP office, and specify the AP model and serial ID.

[AC] wlan ap office model WA6320

[AC-wlan-ap-office] serial-id 219801A28N819CE0003T

[AC-wlan-ap-office] quit

# Create AP group group1 and create an AP grouping rule by AP names to add AP office to AP group group1.

[AC] wlan ap-group group1

[AC-wlan-ap-group-group1] ap office

# Bind service template service to radio 1 in AP group group1.

[AC-wlan-ap-group-group1] ap-model WA6320

[AC-wlan-ap-group-group1-ap-model-WA6320] radio 1

[AC-wlan-ap-group-group1-ap-model-WA6320-radio-1] service-template service

# Enable radio 1.

[AC-wlan-ap-group-group1-ap-model-WA6320-radio-1] radio enable

[AC-wlan-ap-group-group1-ap-model-WA6320-radio-1] quit

[AC-wlan-ap-group-group1-ap-model-WA6320] quit

[AC-wlan-ap-group-group1] quit

Configuring the switch

# Enable the DHCP server.

<Switch> system-view

[Switch] dhcp enable

# Create VLAN 100. The switch will use this VLAN to forward the traffic on the CAPWAP tunnels between the AC and AP.

[Switch] vlan 100

[Switch-vlan100] quit

# Create VLAN 200. The switch will use this VLAN to forward packets for wireless clients.

[Switch] vlan 200

[Switch-vlan200] quit

# Configure GigabitEthernet 1/0/1 (the port connected to the AC) as a trunk port, and assign the trunk port to VLAN 100 and VLAN 200.

[Switch] interface gigabitethernet 1/0/1

[Switch-GigabitEthernet1/0/1] port link-type trunk

[Switch-GigabitEthernet1/0/1] port trunk permit vlan 100 200

[Switch-GigabitEthernet1/0/1] quit

# Configure GigabitEthernet 1/0/2 (the port connected to the AP) as a trunk port, assign the port to VLAN 100 and VLAN 200, and set the PVID of the port to 100.

[Switch] interface gigabitethernet 1/0/2

[Switch-GigabitEthernet1/0/2] port link-type trunk

[Switch-GigabitEthernet1/0/2] port trunk permit vlan 100 200

[Switch-GigabitEthernet1/0/2] port trunk pvid vlan 100

# Enable PoE on GigabitEthernet 1/0/2.

[Switch-GigabitEthernet1/0/2] poe enable

[Switch-GigabitEthernet1/0/2] quit

# Assign IP address 2.2.2.100/24 to VLAN-interface 100.

[Switch] interface vlan-interface 100

[Switch-Vlan-interface100] ip address 2.2.2.100 255.255.255.0

[Switch-Vlan-interface100] quit

# Assign IP address 2.2.1.2/24 to VLAN-interface 200.

[Switch] interface vlan-interface 200

[Switch-Vlan-interface200] ip address 2.2.1.2 255.255.255.0

[Switch-Vlan-interface200] quit

# Create a DHCP address pool named 100, and specify subnet 2.2.2.0/24 and gateway IP address 2.2.2.1 in the DHCP address pool.

[Switch] dhcp server ip-pool 100

[Switch-dhcp-pool-100] network 2.2.2.0 mask 255.255.255.0

[Switch-dhcp-pool-100] gateway-list 2.2.2.1

[Switch-dhcp-pool-100] option 138 ip-address 2.2.2.1

[Switch-dhcp-pool-100] quit

# Create a DHCP address pool named 200, and specify subnet 2.2.1.0/24 and gateway IP address 2.2.1.1 in the DHCP address pool.

[Switch] dhcp server ip-pool 200

[Switch-dhcp-pool-200] network 2.2.1.0 mask 255.255.255.0
