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-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 actual serial ID of an AP to uniquely identify that 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

[AC-Vlan-interface100] quit

# 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

[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 1, 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 1 100 200

[AC-GigabitEthernet1/0/1] quit

2.     Enable port security and enable EAP relay for 802.1X authentication.

[AC] port-security enable

[AC] dot1x authentication-method eap

3.     Configure a RADIUS scheme:

# Create a RADIUS scheme named radius1 and enter its view.

[AC] radius scheme radius1

# Specify the server at 2003::2 as the primary authentication RADIUS server.

[AC-radius-radius1] primary authentication ipv6 2003::2

# Specify the server at 2003::2 as the primary accounting RADIUS server.

[AC-radius-radius1] primary accounting ipv6 2003::2

# Set the shared key to 12345 in plaintext form for secure communication with the RADIUS authentication server.

[AC-radius-radius1] key authentication simple 12345

# Set the shared key to 12345 in plaintext form for secure communication with the RADIUS accounting server.

[AC-radius-radius1] key accounting simple 12345

# Set the real-time accounting interval to 3 minutes.

[AC-radius-radius1] timer realtime-accounting 3

# Specify IPv6 address 2001::1 as the source IPv6 address of outgoing RADIUS packets.

[AC-radius-radius1] nas-ip ipv6 2001::1

[AC-radius-radius1] quit

4.     Configure an authentication domain:

# Create an ISP domain named dom1 and enter its view.

[AC] domain dom1

# Apply RADIUS scheme radius1 to ISP domain dom1 for LAN user authentication, authorization, and accounting.

[AC-isp-dom1] authentication lan-access radius-scheme radius1

[AC-isp-dom1] authorization lan-access radius-scheme radius1

[AC-isp-dom1] accounting lan-access radius-scheme radius1

[AC-isp-dom1] quit

5.     Configure ACLs:

# Create IPv6 advanced ACL 3000 and enter its view.

[AC] acl ipv6 advanced 3000

# Create an ACL rule to permit all IPv6 packets.

[AC-acl-ipv6-adv-3000] rule permit ipv6

[AC-acl-ipv6-adv-3000] quit

# Create IPv6 advanced ACL 3001 and enter its view.

[AC] acl ipv6 advanced 3001

# Create an ACL rule to permit all UDP packets.

[AC-acl-ipv6-adv-3001] rule permit udp

# Create an ACL rule to deny all TCP packets.

[AC-acl-ipv6-adv-3001] rule deny tcp

[AC-acl-ipv6-adv-3001] quit

6.     Configure a wireless service:

# Create a service template named 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 clients coming online through the service template to VLAN 200.

[AC-wlan-st-service] vlan 200

# Set the AKM mode to 802.1X authentication.

[AC-wlan-st-service] akm mode dot1x

# Set the CCMP cipher suite for frame encryption and enable the RSN-IE in the beacon and probe responses.

[AC-wlan-st-service] cipher-suite ccmp

[AC-wlan-st-service] security-ie rsn

# Set the authentication mode to 802.1X authentication.

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

# Specify ISP domain dom1 as the 802.1X authentication domain.

[AC-wlan-st-service] dot1x domain dom1

# Enable snooping DHCPv6 packets and enable snooping ND packets.

[AC-wlan-st-service] client ipv6-snooping dhcpv6-learning enable

[AC-wlan-st-service] client ipv6-snooping nd-learning enable

# 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

7.     Configure AP settings:

 

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

 

# Create a manual AP named ap1 and specify its model and serial ID.

[AC] wlan ap ap1 model WA6320

[AC-wlan-ap-ap1] serial-id 219801A28N819CE0002T
