Introduction

The following information provides an example for configuring remote 802.1X authentication for wireless clients on an IPv6 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 IPv6 basics, WLAN access, WLAN security, WLAN authentication, and 802.1X.

Example: Configuring remote authentication for 802.1X clients (IPv6)

Network configuration

As shown in Figure 1, the switch acts as a DHCPv6 server to assign IPv6 addresses to the AP and the client. IMC acts as the RADIUS server.

Configure the AC, the client, the switch, and the RADIUS server to meet the following requirements:

·     The AC uses the RADIUS server to perform 802.1X authentication for the wireless client.

·     The AC uses the open system authentication for the client at the data link layer. This is the default authentication method.

·     The AC uses the 802.1X AKM mode to secure data transmission between the client and the AP.

·     The cipher suite is CCMP.

Figure 1 Network diagram

 

Restrictions and guidelines

When you configure remote 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.

·     For the IMC server to dynamically change the client authorization information or forcibly disconnect clients, enable the RADIUS session-control feature on the AC.

Procedures

Configuring the AC

1.     Configure interfaces on the AC:

# Create VLAN 100 and VLAN-interface 100, and assign an IPv6 address to the VLAN interface. The AC will use this IP address to establish CAPWAP tunnels with the AP.

<AC> system-view

[AC] vlan 100

[AC-vlan100] quit

[AC] interface vlan-interface 100

[AC-Vlan-interface100] ipv6 address 2001::1 64

[AC-Vlan-interface100] quit

# Create VLAN 200 and VLAN-interface 200, and assign an IPv6 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] ipv6 address 2004::1 64
