Introduction

The following information provides an AP license synchronization configuration example.

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 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.

The following information is provided based on the assumption that you have basic knowledge of AP license synchronization.

Example: Configuring AP license synchronization

Network requirements

As shown in Figure 1, the APs connect to AC 1 and AC 2 through the switch and the APs provide wireless service for clients. Set the SSID to service and enable AP license synchronization on AC 1 and AC 2. The two ACs back up licenses for each other.

Figure 1 Network diagram

 

Configuration restrictions and guidelines

When the master AC fails, the backup AC will take over and becomes the new master AC. The licenses synchronized to the new master AC will be valid for a 30-day grace period.

Configuration procedures

Configuring the AC 1

1.     Configure interfaces on the AC 1:

# Configure VLAN-interface 100 and assign it an IP address. The AC 1 will use this IP address to establish CAPWAP tunnels with APs.

<AC1> system-view

[AC1] vlan 100

[AC1-vlan100] quit

[AC1] interface vlan-interface 100

[AC1-Vlan-interface100] ip address 112.12.1.25 16

[AC1-Vlan-interface100] quit

# Configure VLAN-interface 200 and assign it an IP address. The AC 1 will use VLAN 200 for client access.

[AC1] vlan 200

[AC1-vlan200] quit

[AC1] interface vlan-interface 200

[AC1-Vlan-interface200] ip address 112.13.1.25 16

[AC1-Vlan-interface200] quit

# Configure GigabitEthernet 1/0/1 that connects the AC 1 to the switch as a trunk port.

[AC1] interface gigabitethernet1/0/1

[AC1-GigabitEthernet1/0/1] port link-type trunk

# Remove the trunk port from VLAN 1, and assign the port to VLANs 100 and 200.

[AC1-GigabitEthernet1/0/1] undo port trunk permit vlan 1

[AC1-GigabitEthernet1/0/1] port trunk permit vlan 100 200

[AC1-GigabitEthernet1/0/1] quit

# Enable AP license synchronization on AC 1 and configure AC 1 as the master AC.

[AC1] wlan ap-license-group

[AC1-wlan-ap-license-group] local ip 112.12.1.25

[AC1-wlan-ap-license-group] member ip 112.12.1.26

[AC1-wlan-ap-license-group] ap-license-synchronization enable

[AC1-wlan-ap-license-group] quit

2.     Configure the wireless service:

# Create wireless service template service and enter its view.

[AC1] wlan service-template service

# Set the SSID to service.

[AC1-wlan-st-service] ssid service

# Assign clients coming online through service template service to VLAN 200.

[AC1-wlan-st-service] vlan 200

# Set the AKM mode to PSK, and specify the plaintext preshared key as 12345678.

[AC1-wlan-st-service] akm mode psk

[AC1-wlan-st-service] preshared-key pass-phrase simple 12345678

# Set the cipher suite to CCMP and set the security IE to RSN.

[AC1-wlan-st-service] cipher-suite ccmp

[AC1-wlan-st-service] security-ie rsn

# Configure the AC to forward client data traffic. If the AC acts as the client traffic forwarder by default, skip this step.

[AC1-wlan-st-service] client forwarding-location ac

# Enable service template service.

[AC1-wlan-st-service] service-template enable

[AC1-wlan-st-service] quit

3.     Configure the AP:

 

NOTE: In a large-scale network, configure AP settings in AP group view instead of AP view as a best practice.

 

# Create AP ap1, and specify the AP model and serial ID.

[AC1] wlan ap ap1 model WA6320

[AC1-wlan-ap-ap1] serial-id 219801A28N819CE0002T

[AC1-wlan-ap-ap1] quit

# Create AP group group1, and configure a grouping rule by AP name to add AP ap1 to the group.

[AC1] wlan ap-group group1

[AC1-wlan-ap-group-group1] ap ap1

# Bind service template service to radio 1, and enable radio 1.

[AC1-wlan-ap-group-group1] ap-model WA6320

[AC1-wlan-ap-group-group1-ap-model-WA6320] radio 1

[AC1-wlan-ap-group-group1-ap-model-WA6320-radio-1] service-template service

[AC1-wlan-ap-group-group1-ap-model-WA6320-radio-1] radio enable

[AC1-wlan-ap-group-group1-ap-model-WA6320-radio-1] quit

[AC1-wlan-ap-group-group1-ap-model-WA6320] quit

[AC1-wlan-ap-group-group1] quit

Configuring the AC 2

1.     Configure interfaces on the AC 2:

# Configure VLAN-interface 100 and assign it an IP address. The AC 2 will use this IP address to establish CAPWAP tunnels with APs.

<AC2> system-view

[AC2] vlan 100

[AC2-vlan100] quit

[AC2] interface vlan-interface 100

[AC2-Vlan-interface100] ip address 112.12.1.26 16

[AC2-Vlan-interface100] quit

# Configure VLAN-interface 200 and assign it an IP address. The AC 2 will use VLAN 200 for client access.

[AC2] vlan 200

[AC2-vlan200] quit

[AC2] interface vlan-interface 200

[AC2-Vlan-interface200] ip address 112.13.1.26 16
