Introduction

This document provides an example for configuring PSK authentication and MAC authentication.

Prerequisites

This document 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 in this document 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.

This document assumes that you have basic knowledge of AAA, MAC authentication, WLAN authentication, and WLAN access.

Example: Configuring MAC authentication and PSK authentication

Network configuration

As shown in Figure 1, the AC acts as a DHCP server to provide IP addresses for the AP and the client. The AC centrally forwards the client traffic.

To control the client's access to network resources, complete the following tasks:

·     Configure VLAN 200 as the access VLAN of the client.

·     Configure the AC to use the RADIUS server to perform MAC authentication for the client.

·     Set the AKM mode to PSK to secure data transmission between the client and the AP.

Figure 1 Network diagram

 

Restrictions and guidelines

When you configure MAC authentication with the PSK AKM mode for wireless clients, follow these restrictions and guidelines:

·     On the AC, specify the user account format for MAC authentication. In this example, the MAC address of the client is used as the username and password. Make sure the username and password configuration on the RADIUS server are consistent with the configuration on the AC.

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

·     Remove the ports that connect the AC to the AP from VLAN 1 in case there are too many packets in VLAN 1.

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 a CAPWAP tunnel with the AP.

<AC> system-view

[AC] vlan 100

[AC-vlan100] quit

[AC] interface vlan-interface 100

[AC-Vlan-interface100] ip address 112.12.1.25 16

[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 112.13.1.25 16

[AC-Vlan-interface200] quit

# Configure GigabitEthernet 1/0/1 (port that connects the AC and the switch) as a trunk port, remove the port from VLAN 1, and assign the port to VLANs 100 and 200.

[AC] interface gigabitethernet 1/0/1

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

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

# Set the PVID of GigabitEthernet 1/0/1 to VLAN 100.

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

[AC-GigabitEthernet1/0/1] quit

2.     Configure DHCP:

# Enable DHCP.

[AC] dhcp enable

# Create a DHCP address pool named vlan100, and specify subnet 112.12.0.0/16 and gateway IP address 112.12.1.25 in the DHCP address pool.

[AC] dhcp server ip-pool vlan100

[AC-dhcp-pool-vlan100] network 112.12.0.0 mask 255.255.0.0

[AC-dhcp-pool-vlan100] gateway-list 112.12.1.25

[AC-dhcp-pool-vlan100] quit

# Create a DHCP address pool named vlan200, and specify subnet 112.13.0.0/16 and gateway IP address 112.13.1.25 in the DHCP address pool.

[AC] dhcp server ip-pool vlan200

[AC-dhcp-pool-vlan200] network 112.13.0.0 mask 255.255.0.0

[AC-dhcp-pool-vlan200] gateway-list 112.13.1.30

[AC-dhcp-pool-vlan200] quit

3.     Configure RADIUS-based MAC authentication:

# Create a RADIUS scheme named office and enter its view.

[AC-radius-office] primary authentication 8.1.1.50

[AC-radius-office] primary accounting 8.1.1.50

# Specify the shared keys for RADIUS authentication and accounting.

[AC-radius-office] key authentication simple 123456789

[AC-radius-office] key accounting simple 123456789

# Exclude the ISP domain names from the usernames sent to the RADIUS servers.

[AC-radius-office] user-name-format without-domain

# Specify IP address 112.12.1.25 as the source IP address for outgoing RADIUS packets.

[AC-radius-office] nas-ip 112.12.1.25

[AC-radius-office] quit

# Create an ISP domain named office1 and enter its view.

[AC] domain office1

# Apply RADIUS scheme office to ISP domain office1 for authentication, authorization, and accounting of LAN users.

[AC-isp-office1] authentication lan-access radius-scheme office

[AC-isp-office1] quit

# Configure MAC authentication to use MAC-based accounts. Each MAC address is in the hexadecimal notation without hyphens, and letters are in lower case.

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

4.     Configure a wireless service:

# Create a service template named 1 and enter its view.

[AC] wlan service-template 1

# Configure the SSID of service template 1 as service.

[AC-wlan-st-1] ssid service

# Assign clients coming online through the service template to VLAN 200.

# Set the authentication mode to MAC authentication.

[AC-wlan-st-1] client-security authentication-mode mac

# Specify ISP domain office1 as the MAC authentication domain.
