Introduction

The following information provides an IPv6 access configuration example.

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 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 IPv6 basics and WLAN access.

Example: Configuring IPv6 WLAN access

Network configuration

As shown in Figure 1, the Layer 3 switch acts as a DHCP server to assign IPv6 addresses to the AP and Client 1 and assign an IPv6 prefix to Client 2. Configure wireless services to ensure that the WLAN uses IPv6 addresses and Client 1 and Client 2 can access the WLAN. Assume that centralized forwarding is used in this example.

Figure 1 Network diagram

 

Restrictions and guidelines

When you configure IPv6 access, follow these restrictions and guidelines:

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

·     To prevent too many packets from entering VLAN 1, configure the switch's interface that connects the switch to the AP to deny packets from VLAN 1.

Procedures

Configuring the AC

1.     Configure the interfaces of the AC:

# Create VLAN 100 and VLAN-interface 100, and assign the interface an IPv6 address. The AC will use this IPv6 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] ipv6 address 2001::1 64

[AC-Vlan-interface100] quit

# Create VLAN 200 and VLAN 400. The AC uses the VLANs to forward client traffic.

[AC] vlan 200

[AC-vlan200] quit

[AC] vlan 400

[AC-vlan400] quit

# Configure GigabitEthernet 1/0/1 that connects the AC to the switch as a trunk port, remove the port from VLAN 1, and assign the port to VLANs 100, 200, and 400.

[AC] interface gigabitethernet 1/0/1

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

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

[AC-GigabitEthernet1/0/1] port trunk permit vlan 100 200 400

[AC-GigabitEthernet1/0/1] quit

2.     Configure IPv6 static routes.

[AC] ipv6 route-static 3001::0 64 2001::2

[AC] ipv6 route-static 4001::0 64 2001::2

3.     Configure wireless services:

# Create service template 1 and enter its view.

[AC] wlan service-template 1

# Set the SSID to service1.

[AC-wlan-st-1] ssid service1

# Enable the service template.

[AC-wlan-st-1] service-template enable

# Enable snooping DHCPv6 and ND packets.

[AC-wlan-st-2] client ipv6-snooping dhcpv6-learning enable

[AC-wlan-st-2] client ipv6-snooping nd-learning enable

[AC-wlan-st-2] quit

# Create service template 2 and enter its view.

[AC] wlan service-template 2

# Set the SSID to service2.

[AC-wlan-st-2] ssid service2

# Enable the service template.

[AC-wlan-st-2] service-template enable

# Enable snooping DHCPv6 and ND packets.

[AC-wlan-st-2] client ipv6-snooping dhcpv6-learning enable

[AC-wlan-st-2] client ipv6-snooping nd-learning enable

[AC-wlan-st-2] quit

4.     Configure the AP:

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

[AC] wlan ap officeap model WA4320i-ACN

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

# Bind service template 1 and VLAN 200 to radio 1.

[AC-wlan-ap-officeap] radio 1

[AC-wlan-ap-officeap-radio-1] service-template 1 vlan 200

# Enable radio 1.

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

[AC-wlan-ap-officeap-radio-1] return

# Bind service template 2 and VLAN 400 to radio 2.

[AC-wlan-ap-officeap] radio 2

[AC-wlan-ap-officeap-radio-2] service-template 2 vlan 400

# Enable radio 2.

[AC-wlan-ap-officeap-radio-2] radio enable

[AC-wlan-ap-officeap-radio-2] return

Configuring the switch

1.     Configure switch interfaces:

# Create VLAN 100, VLAN 300, VLAN-interface 100, and VLAN-interface 300, and assign IPv6 addresses to the VLAN interfaces. The switch will use VLAN 100 and VLAN 300 to forward packets between AC and AP.
