Introduction

The following information provides an example for configuring APs to associate with the AC at Layer 2 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 IPv6 basics and WLAN access.

Restrictions and guidelines

When you configure AP's association with the AC at Layer 2 on an IPv6 network, 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.

Example: Configuring an AP to associate with the AC at Layer 2 (IPv6)

Network configuration

As shown in Figure 1, the AC acts as a DHCPv6 server to assign IPv6 addresses to the AP, client, and host, and the Layer 2 switch supplies power to the AP through PoE. Assume centralized forwarding is used in this example.

Configure wireless services to enable the client to access the wireless services and communicate with the host.

Procedures

Configuring the AC

1.     Configure AC interfaces:

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

<AC> system-view

[AC] vlan 100

[AC-vlan100] interface vlan-interface 100

[AC-Vlan-interface100] ipv6 address 1::1:0:0:1/96

# 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-interface100] vlan 200

[AC-vlan200] interface vlan-interface 200

[AC-Vlan-interface200] ipv6 address 1::2:0:0:1/96

# Create VLAN 300 and VLAN-interface 300, and assign an IPv6 address to the VLAN interface. The AC will use this IPv6 address to associate with the host.

[AC-Vlan-interface200] vlan 300

[AC-vlan300] interface vlan-interface 300

[AC-Vlan-interface300] ipv6 address 1::3:0:0:1/96

[AC-Vlan-interface300] 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 300.

[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 100 200 300

# Configure the PVID as VLAN 100.

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

[AC-GigabitEthernet1/0/1] quit

2.     Configure DHCPv6:

# Enable the DHCPv6 server on VLAN-interface 100, VLAN-interface 200, and VLAN-interface 300, and apply address pools 1, 2, and 3 to these interfaces, respectively.

[AC] interface vlan-interface 100

[AC-Vlan-interface100] ipv6 dhcp select server

[AC-Vlan-interface100] ipv6 dhcp server apply pool 1

[AC-Vlan-interface100] quit

[AC] interface vlan-interface 200

[AC-Vlan-interface200] ipv6 dhcp server apply pool 2

[AC-Vlan-interface200] ipv6 dhcp select server

[AC-Vlan-interface200] quit

[AC] interface vlan-interface 300

[AC-Vlan-interface300] ipv6 dhcp server apply pool 3

[AC-Vlan-interface300] ipv6 dhcp select server

[AC-Vlan-interface300] quit

# Disable RA message suppression, and set both the managed address configuration flag (M) and the other stateful configuration flag (O) to 1 in RA advertisements to be sent for the created VLAN interfaces.

[AC] interface vlan-interface 100

[AC-Vlan-interface100] undo ipv6 nd ra halt

[AC-Vlan-interface100] ipv6 nd autoconfig managed-address-flag

[AC-Vlan-interface100] ipv6 nd autoconfig other-flag

[AC-Vlan-interface100] quit

[AC] interface vlan-interface 200

[AC-Vlan-interface200] undo ipv6 nd ra halt

[AC-Vlan-interface200] ipv6 nd autoconfig managed-address-flag

[AC] interface vlan-interface 300

[AC-Vlan-interface300] undo ipv6 nd ra halt

[AC-Vlan-interface300] ipv6 nd autoconfig managed-address-flag

[AC-Vlan-interface300] ipv6 nd autoconfig other-flag

[AC-Vlan-interface300] quit

# Create DHCPv6 address pool 1 to assign an IPv6 address to the AP, and specify subnet 1::1:0:0:0/96 in the DHCP address pool.

[AC] ipv6 dhcp pool 1

[AC-dhcp6-pool-1] network 1::1:0:0:0/96

[AC-dhcp6-pool-1] quit

# Create DHCPv6 address pool 2 to assign an IPv6 address to the client, and specify subnet 1::2:0:0:0/96 in the DHCP address pool.
