Introduction

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

Prerequisites

This document 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 WLAN access.

Example: Configuring an AP to associate with the AC at Layer 3

Network configuration

As shown in Figure 1, the AC is attached to the Layer 3 switch and the Layer 3 switch acts as a DHCP server to assign IP addresses to the AP, client, and host. Assume centralized forwarding is used in this example.

Configure the following settings for the client to communicate with the host:

·     Configure the client to access the WLAN through VLAN 200, and the host to access the network through VLAN 300.

·     Assign the AC to VLAN 100 and the AP to VLAN 400, and configure the AC to establish tunnels with the AP through a Layer 3 network.

·     Configure Layer 2 switch 1 to supply power to the AP through PoE.

Figure 1 Network diagram

 

Analysis

·     For the AP, the client, and the host to obtain IP addresses through DHCP, enable the DHCP server feature on the Layer 3 switch.

·     For the AC to reach the Layer 3 switch, configure a static route on the AC with the Layer 3 switch as the next hop.

·     For the AP to establish tunnels with the AC, configure the DHCP server to send the AC's IP address to the AP through DHCP Option 43.

·     For Layer 2 switch 1 to supply power to the AP, enable PoE on the switch.

·     For the client to access the network, configure wireless services on the AC.

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.

·     Configure the switch's interface that connects Layer 2 switch 1 to the AP as an access port.

Procedures

Configuring the AC

1.     Configure AC interfaces:

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

<AC> system-view

[AC] vlan 100

[AC-vlan100] quit

[AC] interface vlan-interface100

[AC-Vlan-interface100] ip address 192.168.10.1 255.255.255.0

[AC-Vlan-interface100] quit

# Create VLAN 200. The AC will use VLAN 200 to forward client traffic.

[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 a static route, whose next hop is the Layer 3 switch.

[AC] ip route-static 0.0.0.0 0 24 192.168.10.83

3.     Configure wireless services:

# Create service template 1 and enter its view.

[AC] wlan service-template 1

# Configure the SSID as service.

[AC-wlan-st-1] ssid service

# Enable the service template.

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

[AC-wlan-st-1] 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 210235A1GQB147031200

# 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

Configuring the Layer 3 switch

1.     Configure switch interfaces:

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