Introduction

The following information provides an example for configuring PSK encryption.

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 WLAN access and WLAN security.

Example: Configuring PSK encryption

Network configuration

As shown in Figure 1, the switch acts as a DHCP server to assign IP addresses to the AP and the client. Perform the following tasks:

·     Configure PSK on the AC to enable the client to use PSK for encryption.

·     Configure open system authentication and bypass authentication so that the client can access the WLAN without being authenticated.

·     Configure PSK as the authentication and key management (AKM) mode.

·     Set the cipher suite to CCMP.

·     Set the security IE to RSN.

Figure 1 Network diagram

 

Restrictions and guidelines

When you configure PSK encryption, follow these restrictions and guidelines:

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

·     Configure a pre-shared key if the AKM mode is PSK.

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-interface 100

[AC-Vlan-interface100] ip address 192.1.1.1 16

[AC-Vlan-interface100] quit

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

[AC] vlan 200

[AC-vlan200] quit

[AC] interface vlan-interface 200

[AC-Vlan-interface200] ip address 192.2.1.1 24

[AC-Vlan-interface200] 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 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

# Specify VLAN 200 for clients to access the WLAN defined by the service template.

[AC-wlan-st-1] vlan 200

# Set the AKM mode to PSK, and configure simple character string of 12345678 as the PSK.

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

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

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

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

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

# Configure 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-officeap] quit

# 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 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

# 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

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

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

Configuring the switch

1.     Configure switch interfaces:

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

<Switch> system-view

[Switch] vlan 100

[Switch-vlan100] quit

[Switch] interface vlan-interface 100

[Switch-Vlan-interface100] ip address 192.1.1.2 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 192.2.1.2 24

[Switch-Vlan-interface200] quit

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

[Switch] interface gigabitethernet 1/0/1

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

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

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

[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, set the PVID to VLAN 100, and assign the port to VLAN 100.

[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

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

# Enable PoE on GigabitEthernet 1/0/2.

[Switch-GigabitEthernet1/0/2] poe enable

[Switch-GigabitEthernet1/0/2] quit

2.     Configure DHCP:

# Enable DHCP.

[Switch] dhcp enable

# Create DHCP address pool vlan100 to assign an IP address to the AP, and specify subnet 192.1.0.0/16 in the DHCP address pool.

[Switch] dhcp server ip-pool vlan100

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

# Exclude IP address 192.1.1.1 from dynamic allocation in the address pool.

[Switch-dhcp-pool-vlan100] forbidden-ip 192.1.1.1

# Specify the gateway address as 192.1.1.2 in the DHCP address pool.

[Switch-dhcp-pool-vlan100] gateway-list 192.1.1.2

[Switch-dhcp-pool-vlan100] quit

# Create DHCP address pool vlan200 to assign an IP address to the client, and specify subnet 192.2.1.0/24 in the DHCP address pool.

[Switch] dhcp server ip-pool vlan200

[Switch-dhcp-pool-vlan200] network 192.2.1.0 mask 255.255.255.0

# Exclude IP address 192.2.1.1 from dynamic allocation in the address pool.

[Switch-dhcp-pool-vlan200] forbidden-ip 192.2.1.1

# Specify the gateway address as 192.2.1.2 and specify the DNS server address in the DHCP address pool. In this example, the gateway also acts as a DNS server.

[Switch-dhcp-pool-vlan200] gateway-list 192.2.1.2

[Switch-dhcp-pool-vlan200] dns-list 192.2.1.2

[Switch-dhcp-pool-vlan200] quit

Verifying the configuration

# Verify that the client has been associated with the WLAN and the AKM mode is PSK.
