Introduction

The following information provides an example for configuring APs to associate with the AC at Layer 3 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 and WLAN access.

Restrictions and guidelines

When you configure AP's association with the AC at Layer 3, 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 3 (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. 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

[AC-Vlan-interface100] quit

# Create VLAN 200. VLAN 200 will be used for client access.

[AC] vlan 200

[AC-vlan200] 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 and 200.

[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

[AC-GigabitEthernet1/0/1] quit

2.     Configure an IPv6 static route.

[AC] ipv6 route-static 1::4:0:0:0 96 1::1:0:0:2

3.     Configure wireless services:

# Create service template 1 and enter its view.

[AC] wlan service-template 1

# Configure the AC to forward client data traffic. You can skip this step if the AC is the client traffic forwarder by default.

[AC–wlan-st-1] client forwarding-location ac

# Configure the SSID as service.

[AC-wlan-st-1] ssid service

# Set the PSK AKM mode and specify plaintext string 12345678 as the preshared key.

[AC-wlan-st-1] akm mode psk

[AC-wlan-st-1] preshared-key pass-phrase simple 12345678

# Set the CCMP cipher suite and enable the RSN security IE.

[AC-wlan-st-1] cipher-suite ccmp

[AC-wlan-st-1] security-ie rsn

# Enable the service template.

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

# Enable snooping DHCPv6 packets and ND packets.

[AC-wlan-st-1] client ipv6-snooping dhcpv6-learning enable

[AC-wlan-st-1] client ipv6-snooping nd-learning enable

[AC-wlan-st-1] quit

4.     Configure the AP:

 

NOTE: In a large-scale network, configure AP groups instead of single APs as a best practice.

 

# Create manual AP ap1, and specify the AP model and serial ID.

[AC] wlan ap ap1 model WA6320

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

[AC-wlan-ap-ap1] quit

# Create AP group group1 and add the AP to the AP group.

[AC] wlan ap-group group1

[AC-wlan-ap-group-group1] ap ap1

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

[AC-wlan-ap-group-group1] ap-model WA6320

[AC-wlan-ap-group-group1-ap-model-WA6320] radio 1

[AC-wlan-ap-group-group1-ap-model-WA6320-radio-1] service-template 1 vlan 200

# Enable radio 1.

[AC-wlan-ap-group-group1-ap-model-WA6320-radio-1] radio enable

[AC-wlan-ap-group-group1-ap-model-WA6320-radio-1] return

Configuring the Layer 3 switch

1.     Configure switch interfaces:

# Create VLAN 100, VLAN 400, VLAN-interface 100 and VLAN-interface 400, and assign IPv6 addresses to the VLAN interfaces. The switch will use VLAN 100 and VLAN 400 to forward packets between AC and AP.

<L3 switch> system-view

[L3 switch] vlan 100

[L3 switch-GigabitEthernet1/0/3] port access vlan 300

[L3 switch-GigabitEthernet1/0/3] quit

2.     Configure DHCPv6:

# Enable the DHCPv6 server on VLAN-interface 200, VLAN-interface 300, and VLAN-interface 400, and apply address pools 1, 2, and 3 to these interfaces, respectively.

[L3 switch] interface vlan-interface 200
