Introduction

The following information provides a downlink VLAN management configuration example for fit-mode APs.

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 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 AP management, radio management, WLAN access, VLAN, and local forwarding.

Example: Configuring downlink VLAN management for fit-mode APs

Network configuration

As shown in Figure 1, the switch acts as the DHCP server to assign IP addresses to the AP, the client, and the PC. The AP and the AC use VLAN 100 to establish a CAPWAP tunnel, the client uses VLAN 200 to access the wireless network, and the PC uses VLAN 300 to access the wired network.

·     Configure local forwarding on the AC for the AP to directly forward client traffic.

·     Connect the PC to a downlink Ethernet interface on the AP and make sure the PC can visit the external network.

Figure 1 Network diagram

 

Analysis

For the configuration to be deployed to the AP, configure remote configuration synchronization or deploy the map file.

Restrictions and guidelines

·     For configuration to be deployed correctly, do not attach Tab characters or spaces to the end of command lines in the map file.

·     Use the actual AP model and serial ID to configure the AP.

·     If a backup AC is configured, make sure the backup AC is also uploaded with the map file.

Procedures

Configuring the AC

1.     Configure the interfaces of the AC:

# Create VLAN 100 and VLAN-interface 100, and assign an IP address to the 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-interface 100

[AC-Vlan-interface100] ip address 192.168.1.2 24

[AC-Vlan-interface100] quit

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

[AC] interface gigabitethernet 1/0/1

[AC-GigabitEthernet1/0/1] port link-type trunk

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

[AC-GigabitEthernet1/0/1] quit

2.     Configure a wireless service:

# Create service template 1 and enter its view.

[AC] wlan service-template 1

# Set the SSID to service.

[AC-wlan-st-1] ssid service

# Set the VLAN to VLAN 200.

[AC-wlan-st-1] vlan 200

# Specify PSK as the AKM mode and specify 12345678 as the plaintext key.

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

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

# Specify CCMP as the cipher suite and specify RSN as the security IE.

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

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

# Configure the AP to forward client data traffic.

[AC-wlan-st-1] client forwarding-location ap

# Enable the service template.

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

[AC-wlan-st-1] quit

3.     Configure AP settings:

 

NOTE: To simply AP configuration on a large-scale network, configure AP settings on a per AP group basis as a best practice.

 

# Create manual AP ap1.

[AC] wlan ap ap1 model WA6320H

# Specify the AP serial ID.

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

[AC-wlan-ap-ap1] quit

# Create AP group group1 and configure ap1 as the AP grouping rule.

[AC] wlan ap-group group1

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

# Bind service template 1 to radio 2 for AP group group1.

[AC-wlan-ap-group-group1] ap-model WA6320H

[AC-wlan-ap-group-group1-ap-model-WA6320H] radio 2

[AC-wlan-ap-group-group1-ap-model-WA6320H-radio-2] service-template 1

# Enable radio 2.

[AC-wlan-ap-group-group1-ap-model-WA6320H-radio-2] radio enable

[AC-wlan-ap-group-group1-ap-model-WA6320H-radio-2] quit

[AC-wlan-ap-group-group1-ap-model-WA6320H] quit

4.     To deploy configuration through remote configuration synchronization:

# Create VLANs 200 and 300 in AP group group1.

[AC-wlan-ap-group-group1] vlan 200

[AC-wlan-ap-group-group1-vlan200] quit

[AC-wlan-ap-group-group1] vlan 300

[AC-wlan-ap-group-group1-vlan300] quit

# Specify uplink Ethernet interface GE1/0/1 that connects the AP to the switch as a trunk port, assign the port to all VLANs, set the PVID to 1, and disable port isolation.

[AC-wlan-ap-group-group1] ap-model WA6320H

[AC-wlan-ap-group-group1-ap-model-WA6320H] gigabitethernet 1

[AC-wlan-ap-group-group1-ap-model-WA6320H-gigabitethernet-1] port-isolate disable

[AC-wlan-ap-group-group1-ap-model-WA6320H-gigabitethernet-1] port link-type trunk

[AC-wlan-ap-group-group1-ap-model-WA6320H-gigabitethernet-1] port trunk permit vlan all

[AC-wlan-ap-group-group1-ap-model-WA6320H-gigabitethernet-1] port trunk pvid vlan 1

[AC-wlan-ap-group-group1-ap-model-WA6320H-gigabitethernet-1] quit

# Specify downlink Ethernet interface GE1/0/2 that connects the AP to the PC as an access port, assign the port to VLAN 300, and disable port isolation.

[AC-wlan-ap-group-group1-ap-model-WA6320H] gigabitethernet 2

[AC-wlan-ap-group-group1-ap-model-WA6320H-gigabitethernet-2] port-isolate disable

[AC-wlan-ap-group-group1-ap-model-WA6320H-gigabitethernet-2] port access vlan 300

[AC-wlan-ap-group-group1-ap-model-WA6320H-gigabitethernet-2] quit

[AC-wlan-ap-group-group1-ap-model-WA6320H] quit

# Enable remote configuration synchronization.

[AC-wlan-ap-group-group1] remote-configuration enable

# Synchronize the configuration to the AP.

[AC-wlan-ap-group-group1] remote-configuration synchronize

5.     To deploy configuration through a map configuration file:

 

NOTE: Use a text editor to edit the content of the apcfg.txt file in the configuration order, and upload the file to the AC. After the AP associates with the AC, use the map-configuration command to deploy the file to the AP for the configuration to take effect on the AP.

 

# Edit the apcfg.txt file.

Configuring the switch

1.     Configure switch interfaces:

# Create VLAN 2, VLAN 100, VLAN 200, VLAN 300, and the VLAN interfaces, and assign IP addresses to the VLAN interfaces. The switch will use VLAN 2 as the egress to the external network, VLAN 100 to forward packets between AC and AP, VLAN 200 to forward client traffic, and VLAN 300 for wired network access of the PC.

[Switch-dhcp-pool-vlan300] dns-list 192.168.3.1

[Switch-dhcp-pool-vlan300] quit

3.     Configure default routes for the switch to visit the external IP network. (Details not shown.)

Verifying the configuration

# Verify that the IP address of the client is 192.168.2.2, the IP address of the PC is 192.168.3.2, and both the client and the PC can visit the external network.
