Introduction

The following information provides an example for configuring remote AP.

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 remote AP.

Example: Configuring remote AP

Network configuration

As shown in Figure 1, the switch acts as a DHCP server to assign IP addresses to the AP and the clients. Configure remote AP on the AC so that the AP can still provide services for clients when the tunnel between the AP and the AC is disconnected.

Figure 1 Network diagram

 

Restrictions and guidelines

When you configure remote AP, follow these restrictions and guidelines:

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

·     For also new clients to come online, make sure the clients are associated with and authenticated at APs. In this case, use simple text or PSK encryption as a best practice.

·     Remote AP takes effect only on an AP that operates in local forwarding mode.

·     For GigabitEthernet 1/0/1 on the AP to join VLAN 200, edit the AP configuration file, and upload it to the storage media of the AC.

Procedures

Configuring the AC

1.     Configure interfaces on the AC:

# 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 CAPWAP tunnels with APs.

<AC> system-view

[AC] vlan 100

[AC-vlan100] quit

[AC] interface vlan-interface 100

[AC-Vlan-interface100] ip address 192.1.0.1 16

[AC-Vlan-interface100] quit

# Create VLAN 200 and VLAN-interface 200, and assign an IP address to the VLAN interface. The AC will use VLAN 200 for client access.

[AC] vlan 200

[AC-vlan200] quit

[AC] interface vlan-interface 200

[AC-Vlan-interface200] ip address 192.2.0.1 16

[AC-Vlan-interface200] quit

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

[AC] interface gigabitethernet 1/0/1

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

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

[AC-GigabitEthernet1/0/1] quit

2.     Configure wireless services:

# Create a service template named 1 and enter its view.

[AC] wlan service-template 1

# Configure the SSID of service template 1 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 RSN security IE.

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

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

# Specify APs as the client traffic forwarder.

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

# To ensure that new clients can come online, enable client authentication and association on APs.

[AC-wlan-st-1] client-security authentication-location ap

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

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

[AC] wlan ap officeap model WA6320

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

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

[AC] wlan ap-group group1

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

# Bind service template 1 and VLAN 200 to radio 2.

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

[AC-wlan-ap-group-group1-ap-model-WA6320] radio 2

[AC-wlan-ap-group-group1-ap-model-WA6320-radio-2] service-template 1 vlan 200

# Enable radio 2.

[AC-wlan-ap-group-group1-ap-model-WA6320-radio-2] radio enable

[AC-wlan-ap-group-group1-ap-model-WA6320-radio-2] quit

# Deploy configuration file apcfg.txt to the AP.

[AC-wlan-ap-group-group1-ap-model-WA6320] map-configuration apcfg.txt

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

# Enable remote AP.

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

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

Configuring the switch

1.     Configure interfaces on the switch:

# Create VLAN 100 and VLAN-interface 100, and assign an IP address to the VLAN interface. The switch will use VLAN 100 to forward the traffic on the CAPWAP tunnel between the AC and AP.

<Switch> system-view

[Switch] vlan 100

[Switch-vlan100] quit

[Switch] interface vlan-interface 100

[Switch-Vlan-interface100] ip address 192.1.0.2 16

[Switch-Vlan-interface100] quit

# Create VLAN 200 and VLAN-interface 200, and assign an IP address to the VLAN interface. The switch will use VLAN 200 to forward client traffic.

[Switch] vlan 200

[Switch-vlan200] quit

[Switch] interface vlan-interface 200

[Switch-Vlan-interface200] ip address 192.2.0.2 16

[Switch-Vlan-interface200] quit

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

[Switch] interface gigabitethernet 1/0/1

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

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

[Switch-GigabitEthernet1/0/1] quit

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

[Switch] interface gigabitethernet 1/0/2

[Switch-GigabitEthernet1/0/2] port link-type trunk

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

[Switch-GigabitEthernet1/0/2] port trunk permit vlan 100 200

# Set the PVID of GigabitEthernet 1/0/2 to VLAN 100.

[Switch-GigabitEthernet1/0/2] port trunk pvid vlan 100

[Switch-GigabitEthernet1/0/2] quit

2.     Configure DHCP services:

# Enable DHCP.

[Switch] dhcp enable

# Create a DHCP address pool named vlan100 to assign an IP address to the AP.

[Switch] dhcp server ip-pool vlan100

# In DHCP address pool vlan100, specify subnet 192.1.0.0/16 for dynamic allocation, exclude 192.1.0.1 from dynamic allocation, and specify gateway IP address 192.1.0.2.

[Switch-dhcp-pool-vlan100] network 192.1.0.0 mask 255.255.0.0

[Switch-dhcp-pool-vlan100] forbidden-ip 192.1.0.1

[Switch-dhcp-pool-vlan100] gateway-list 192.1.0.2

[Switch-dhcp-pool-vlan100] quit

# Create a DHCP address pool named vlan200 to assign IP address to clients.

[Switch] dhcp server ip-pool vlan200

# In DHCP address pool vlan200, specify subnet 192.2.0.0/16 for dynamic allocation, and exclude 192.2.0.1 from dynamic allocation. Specify gateway IP address 192.2.0.2, and specify the DNS server address. In this example, the gateway also acts as a DNS server.

[Switch-dhcp-pool-vlan200] network 192.2.0.0 mask 255.255.0.0

[Switch-dhcp-pool-vlan200] forbidden-ip 192.2.0.1

[Switch-dhcp-pool-vlan200] gateway-list 192.2.0.2

[Switch-dhcp-pool-vlan200] dns-list 192.2.0.2

[Switch-dhcp-pool-vlan200] quit

Configuring AP configuration file apcfg.txt

# Copy the following text to a text file and upload the file to the AC.

system-view
