Introduction

The following information provides an example for configuring EAD authentication for wireless clients on an IPv6 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 WLAN access and EAD authentication.

Example: Configuring EAD authentication (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. Configure EAD authentication on the AC to authenticate the client.

Figure 1 Network diagram

 

Restrictions and guidelines

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

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

# Create VLAN 200 and VLAN-interface 200, and assign an IPv6 address to the VLAN interface. The client will use VLAN 200 to access the WLAN.

[AC] vlan 200

[AC-vlan200] quit

[AC] interface vlan-interface 200

[AC-Vlan-interface200] ipv6 address 2004::1 64
