Introduction

The following information provides an example for configuring local MAC-then-802.1X authentication in a wireless network.

Prerequisites

The following information applies to Comware 7-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 MAC authentication, WLAN access, WLAN user access authentication, and 802.1X authentication.

Example: Configuring local MAC-then-802.1X authentication for wireless clients

Network configuration

As shown in Figure 1, an AP is attached to a PoE port on a switch, which acts as a DHCP server to assign IP addresses to the AP and the client.

Configure the AC to meet the following requirements:

·     The AC first performs local MAC authentication for the client.

¡     If the client fails the MAC authentication, the AC performs local 802.1X authentication for the client.

¡     If the client passes the MAC authentication, the AC does not perform 802.1X authentication for the client.

The client can access the network if it passes either MAC authentication or 802.1X authentication.

·     The AC uses 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 MAC-then-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.

·     Make sure the username and password configured on the AC are the same as the MAC address of the client. The username and password formats comply with the MAC authentication user account format.

·     The AC can perform local 802.1X authentication only for the iNode client.

·     Some endpoints by default use random MAC addresses. To ensure successful MAC authentication for such an endpoint, disable the endpoint from using a random MAC address.

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 for 802.1X authentication:

# 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 user for MAC authentication:

# Create a network access user. Set both the username and password to the client's MAC address 3ca9f4144c20.

[AC] local-user 3ca9f4144c20 class network

[AC-luser-network-3ca9f4144c20] password simple 3ca9f4144c20

# Set the service type to lan-access.

[AC-luser-network-3ca9f4144c20] service-type lan-access

[AC-luser-network-3ca9f4144c20] quit

4.     Configure the AC to use the MAC address of each user as both the username and password for MAC authentication. The MAC addresses are in hexadecimal notation without hyphens and with letters in lower case. (The configuration in this step is the default configuration. This step is optional.)

[AC] mac-authentication user-name-format mac-address without-hyphen lowercase

5.     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

6.     Set the 802.1X authentication method to CHAP.

[AC] dot1x authentication-method chap

7.     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 MAC-then-802.1X authentication.

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

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

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

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

[AC-wlan-st-service] mac-authentication domain bbb

# Enable the service template.

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

[AC-wlan-st-service] quit

8.     Configure a manual AP:

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

[AC] wlan ap office model WA4320i-ACN

[AC-wlan-ap-office] serial-id 210235A1GQC158004457

# Enter the view of radio 1, bind service template service to radio 1, and enable the radio.

[AC-wlan-ap-office] radio 1

[AC-wlan-ap-office-radio-1] service-template service

[AC-wlan-ap-office-radio-1] radio enable

[AC-wlan-ap-office-radio-1] quit

[AC-wlan-ap-office] 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 1/0/2

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