Introduction

The following information provides an example for configuring APs to associate with the AC at Layer 2.

Prerequisites

This document 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 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 DHCP and WLAN access.

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

Network configuration

As shown in Figure 1, the AC is attached to a Layer 2 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 configure the AC to establish tunnels with the AP through a Layer 2 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 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 2, follow these restrictions and guidelines:

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

·     Set the link type of the switch's interface that connects Layer 2 switch 1 to the AP to access. Configure the interface to deny packets from VLAN 1 in case there are too many packets in VLAN 1.

Procedures

Configuring the Layer 3 switch

1.     Configure switch interfaces:

# Create VLAN 100 and VLAN-interface 100, and assign IP address 192.168.10.1 to the interface. The switch will use this interface to forward traffic in CAPWAP tunnels 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 192.168.10.1 255.255.255.0

[L3 switch-Vlan-interface100] quit

# Create VLAN 200 and VLAN-interface 200, and assign IP address 192.168.20.1 to the interface. The client will use this VLAN to access the WLAN.

[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 IP address 192.168.30.1 to the interface. The host will use this VLAN to communicate with the AC.

[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

# Set the link type of GigabitEthernet 1/0/1 that connects the switch to Layer 2 switch 1 to trunk, remove the port from VLAN 1, 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] undo port trunk permit vlan 1

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

[L3 switch-GigabitEthernet1/0/1] quit

# Set the link type of GigabitEthernet 1/0/2 that connects the switch to Layer 2 switch 2 to trunk, remove the port from VLAN 1, and assign the port to VLAN 300.

[L3 switch] interfac gigabitEthernet 1/0/3

[L3 switch-GigabitEthernet1/0/3] port link-type trunk

[L3 switch-GigabitEthernet1/0/3] undo port trunk permit vlan 1

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

[L3 switch-GigabitEthernet1/0/3] quit

2.     Configure the DHCP server:

# Enable DHCP server.

<L3 switch> system-view

[L3 switch] dhcp enable

# Create DHCP address pool 1, specify subnet 192.168.10.0/24 in the address pool, and specify the gateway address as 192.168.10.1. The switch will use this address pool to assign an IP address to the AP.

[L3 switch] dhcp server ip-pool 1

[L3 switch-dhcp-pool-1] network 192.168.10.0 mask 255.255.255.0

[L3 switch-dhcp-pool-1] gateway-list 192.168.10.1

# Exclude IP address 192.168.10.2 from dynamic allocation. The excluded IP address is the address of VLAN-interface 100 on the AC.

[L3 switch-dhcp-pool-1] forbidden-ip 192.168.10.2

[L3 switch-dhcp-pool-1] quit

# Create DHCP address pool 2, specify subnet 192.168.20.0/24 in the address pool, specify the gateway address as 192.168.20.1, and specify the address of the DNS server. In this example, the gateway also acts as the DNS server. The switch will use this address pool to assign an IP address to the client.

[L3 switch] dhcp server ip-pool 2

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

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

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

[L3 switch-dhcp-pool-2] quit

# Create DHCP address pool 3, specify subnet 192.168.30.0/24 in the address pool, specify the gateway address as 192.168.30.1, and specify the address of the DNS server. In this example, the gateway also acts as the DNS server. The switch will use this address pool to assign an IP address to the host.

[L3 switch] dhcp server ip-pool 3

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

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

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

[L3 switch-dhcp-pool-3] quit

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] vlan 100

[AC-vlan100] quit

[AC] interface vlan-interface 100

[AC-Vlan-interface100] ip address 192.168.10.2 255.255.255.0

[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 Layer 2 switch 1 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 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

# 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 RSE security IE.

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

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

# Enable 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

# Enable the service template.

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

[AC-wlan-st-1] quit

3.     Configure the AP:

 

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

 

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

[AC] wlan ap officeap model WA6320

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

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

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

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

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

Configuring Layer 2 switch 1

# Create VLANs 100 and 200. The switch will use VLAN 100 to forward packets between the AC and the AP. VLAN 200 will be used for client access.

<L2 switch 1> system-view

[L2 switch 1] vlan 100

[L2 switch 1-vlan100] quit

[L2 switch 1] vlan 200

[L2 switch 1-GigabitEthernet1/0/2] quit

# Configure GigabitEthernet 1/0/2 that connects the switch to the Layer 3 switch as a trunk port, remove the port from VLAN 1, assign the port to VLANs 100 and 200.

[L2 switch 1] interface gigabitEthernet 1/0/3

Configuring Layer 2 switch 2

# Create VLAN 300. The switch will use this VLAN for host access.

<L2 switch 2> system-view

[L2 switch 2] vlan 300

[L2 switch 2-vlan300] quit

# Set the link type of GigabitEthernet 1/0/1 that connects the switch to the Layer 3 switch to trunk, remove the port from VLAN 1, and assign the port to VLAN 300.
