Introduction

This document 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 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 wireless services to enable the client to associate with the AC through the AP and enable the client to communicate with the host. Assign the AC, AP, client, and host to VLANs 100, 400, 200, and 300, respectively.

Figure 1 Network diagram

 

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 the switch to the AP to deny packets from VLAN 1 in case there are too many packets in VLAN 1.

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 to the switch.

[AC] ip route-static 192.168.40.0 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 WA560-WW

[AC-wlan-ap-officeap] serial-id 219801A1NM8182032235

# 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.

<L3 switch> system-view

[L3 switch] vlan 100

[L3 switch-vlan100] quit

[L3 switch] interface vlan-interface 100

[L3 switch-Vlan-interface100] ip address 192.168.10.83 255.255.255.0

[L3 switch-Vlan-interface100] quit

[L3 switch] vlan 400

[L3 switch] interface vlan-interface 400

[L3 switch-Vlan-interface400] ip address 192.168.40.1 255.255.255.0

[L3 switch-Vlan-interface400] quit

# Create VLAN 200 and VLAN-interface 200 and assign an IP address to the VLAN interface. This VLAN will be used for client access.

[L3 switch] vlan 200

[L3 switch-vlan200] quit

[L3 switch] interface vlan-interface 200

[L3 switch-Vlan-interface200] ip address 192.168.20.1 255.255.255.0

[L3 switch-Vlan-interface200] quit

# Create VLAN 300 and VLAN-interface 300 and assign an IP address to the VLAN interface. This VLAN will be used for host access.

[L3 switch] vlan 300

[L3 switch-vlan300] quit

[L3 switch] interface vlan-interface 300

[L3 switch-Vlan-interface300] ip address 192.168.30.1 255.255.255.0

[L3 switch-Vlan-interface300] quit

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

[L3 switch] interface gigabitEthernet 1/0/1

[L3 switch-GigabitEthernet1/0/1] port link-type trunk

[L3 switch-GigabitEthernet1/0/1] port trunk permit vlan 100 200

[L3 switch-GigabitEthernet1/0/1] quit

# Configure GigabitEthernet 1/0/2 that connects the switch to the AP as a trunk port, remove the port from VLAN 1, configure the PVID as VLAN 400, and assign the port to VLANs 200 and 400.

[L3 switch] interface gigabitEthernet 1/0/2

[L3 switch-GigabitEthernet1/0/2] port link-type trunk

[L3 switch-GigabitEthernet1/0/2] undo port trunk permit vlan 1

[L3 switch-GigabitEthernet1/0/2] port trunk permit vlan 200 400

[L3 switch-GigabitEthernet1/0/2] port trunk pvid vlan 400

[L3 switch-GigabitEthernet1/0/2] quit

# Configure GigabitEthernet 1/0/3 that connects the switch to the host as an access port, and assign the port to VLAN 300.

[L3 switch] interface gigabitEthernet 1/0/3

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

[L3 switch-GigabitEthernet1/0/3] quit

2.     Configure DHCP:

# Enable DHCP.

[L3 switch] dhcp enable

# Create DHCP address pool 1 to assign an IP address to the AP, and specify subnet 192.168.40.0/24 in the DHCP address pool.

[L3 switch] dhcp server ip-pool 1

[L3 switch-dhcp-pool-1] network 192.168.40.0 mask 255.255.255.0

# Specify the gateway address as 192.168.40.1 in the DHCP address pool.

[L3 switch-dhcp-pool-1] gateway-list 192.168.40.1

# Configure Option 43 to specify AC IP address in the hexadecimal format in DHCP address pool 1.

[L3 switch-dhcp-pool-1] option 43 hex 8007000001c0a80a01

[L3 switch-dhcp-pool-1] quit

# Create DHCP address pool 2 to assign an IP address to the client, and specify subnet 192.168.20.0/24 in the DHCP address pool.

[L3 switch] dhcp server ip-pool 2

[L3 switch-dhcp-pool-2] network 192.168.20.0 mask 255.255.255.0

# Specify the gateway address as 192.168.20.1 in the DHCP address pool.

[L3 switch-dhcp-pool-2] gateway-list 192.168.20.1

[L3 switch-dhcp-pool-2] quit

# Create DHCP address pool 3 to assign an IP address to the host, and specify subnet 192.168.30.0/24 in the DHCP address pool.

[L3 switch] dhcp server ip-pool 3

[L3 switch-dhcp-pool-3] network 192.168.30.0 mask 255.255.255.0

# Specify the gateway address as 192.168.30.1 in the DHCP address pool.

[L3 switch-dhcp-pool-3] gateway-list 192.168.30.1
