Example for Configuring a WPA2-802.1X-AES Security Policy

Procedure

1. Set the NAC mode to unified on the AC so that users can connect to the network properly.

   <HUAWEI> system-view
   [HUAWEI] authentication unified-mode

   

   If the NAC mode is changed from traditional to unified, the unified mode takes effect after you save the configuration and restart the device.

2. Configure SwitchA and the AC so that the AP and AC can transmit CAPWAP packets.

   # Add GE0/0/1 that connects SwitchA to the AP to management VLAN 100 and add GE0/0/2 that connects SwitchA to the AC to the same VLAN.

   <HUAWEI> system-view
   [HUAWEI] sysname SwitchA
   [SwitchA] vlan batch 100
   [SwitchA] interface gigabitethernet 0/0/1
   [SwitchA-GigabitEthernet0/0/1] port link-type trunk
   [SwitchA-GigabitEthernet0/0/1] port trunk pvid vlan 100
   [SwitchA-GigabitEthernet0/0/1] port trunk allow-pass vlan 100
   [SwitchA-GigabitEthernet0/0/1] port-isolate enable
   [SwitchA-GigabitEthernet0/0/1] quit
   [SwitchA] interface gigabitethernet 0/0/2
   [SwitchA-GigabitEthernet0/0/2] port link-type trunk
   [SwitchA-GigabitEthernet0/0/2] port trunk allow-pass vlan 100
   [SwitchA-GigabitEthernet0/0/2] quit

   # Add GE0/0/1 that connects the AC to SwitchA to VLAN 100.

   [HUAWEI] sysname AC
   [AC] vlan batch 100
   [AC] interface gigabitethernet 0/0/1
   [AC-GigabitEthernet0/0/1] port link-type trunk
   [AC-GigabitEthernet0/0/1] port trunk allow-pass vlan 100
   [AC-GigabitEthernet0/0/1] quit

3. Configure the AC to communicate with the upstream device.

   # Configure VLANIF 101 (service VLAN), VLANIF 102, and VLANIF 103.

   [AC] vlan batch 101 102 103
   [AC] interface vlanif 101
   [AC-Vlanif101] ip address 10.23.101.1 24

   [AC] interface vlanif 103
   [AC-Vlanif103] ip address 10.23.103.2 24
   [AC-Vlanif103] quit

   # Add GE0/0/2 that connects the AC to the Router to VLAN 102.

   [AC] interface gigabitethernet 0/0/2
   [AC-GigabitEthernet0/0/2] port link-type trunk
   [AC-GigabitEthernet0/0/2] port trunk allow-pass vlan 102
   [AC-GigabitEthernet0/0/2] quit

   # Add GE0/0/3 that connects the AC to the RADIUS server to VLAN 103.

   [AC] interface gigabitethernet 0/0/3
   [AC-GigabitEthernet0/0/3] port link-type trunk
   [AC-GigabitEthernet0/0/3] port trunk pvid vlan 103
   [AC-GigabitEthernet0/0/3] port trunk allow-pass vlan 103
   [AC-GigabitEthernet0/0/3] quit

   # On the AC, configure a static route.

   [AC] ip route-static 0.0.0.0 0.0.0.0 10.23.102.1

4. Configure the AC to assign an IP address to the AP and the Router to assign IP addresses to STAs.
   

   Configure the DNS server as required. The common methods are as follows:

   • In interface address pool scenarios, run the dhcp server dns-list ip-address &<1-8> command in the VLANIF interface view.
   • In global address pool scenarios, run the dns-list ip-address &<1-8> command in the IP address pool view.

   # Configure the AC to assign an IP address to the AP from an interface address pool.

   [AC] dhcp enable
   [AC] interface vlanif 100
   [AC-Vlanif100] ip address 10.23.100.1 24
   [AC-Vlanif100] dhcp select interface
   [AC-Vlanif100] quit

   # Configure the AC as a DHCP relay agent, and specify the DHCP server IP address on the DHCP relay agent.

   [AC] interface vlanif 101
   [AC-Vlanif101] dhcp select relay
   [AC-Vlanif101] dhcp relay server-ip 10.23.102.1
   [AC-Vlanif101] quit

   # Configure the Router as a DHCP server to assign IP addresses to STAs from a global address pool. The egress gateway address of the DHCP client is 10.23.101.1, and the network segment of the global address pool is 10.23.101.0/24.

   <Huawei> system-view
   [Huawei] sysname Router
   [Router] dhcp enable
   [Router] ip pool sta
   [Router-ip-pool-sta] gateway-list 10.23.101.1

   [Router-ip-pool-sta] quit
   [Router] vlan batch 102
   [Router] interface vlanif 102
   [Router-Vlanif102] ip address 10.23.102.1 24
   [Router-Vlanif102] dhcp select global
   [Router-Vlanif102] quit
   [Router] interface gigabitethernet 2/0/0
   [Router-GigabitEthernet2/0/0] port link-type trunk
   [Router-GigabitEthernet2/0/0] port trunk allow-pass vlan 102
   [Router-GigabitEthernet2/0/0] quit
   [Router] ip route-static 10.23.101.0 24 10.23.102.2

5. Configure RADIUS authentication parameters.
   

   Configure the same shared key for the AC and RADIUS server.

   # Create a RADIUS server template.

   [AC] radius-server template radius_huawei
   [AC-radius-radius_huawei] radius-server authentication 10.23.103.1 1812
   [AC-radius-radius_huawei] radius-server shared-key cipher huawei@123
   [AC-radius-radius_huawei] quit

   # Configure a RADIUS authentication scheme.

   [AC] aaa
   [AC-aaa] authentication-scheme radius_huawei
   [AC-aaa-authen-radius_huawei] authentication-mode radius
   [AC-aaa-authen-radius_huawei] quit

   # Create an AAA domain and configure the RADIUS server template and authentication scheme.

   [AC-aaa] domain huawei.com
   [AC-aaa-domain-huawei.com] radius-server radius_huawei
   [AC-aaa-domain-huawei.com] authentication-scheme radius_huawei
   [AC-aaa-domain-huawei.com] quit
   [AC-aaa] quit

   

   If the domain name huawei.com is configured, you need to add the domain name when entering the user name.

   # Test whether a STA can be authenticated using RADIUS authentication. A user name test@huawei.com and password 123456 have been configured on the RADIUS server.

   [AC] test-aaa test@huawei.com 123456 radius-template radius_huawei
   Info: Account test succeed.

6. Configure an 802.1X access profile to manage 802.1X access control parameters.

   # Create the 802.1X access profile wlan-dot1x.

   [AC] dot1x-access-profile name wlan-dot1x

   # Set the authentication mode to EAP relay.

   [AC-dot1x-access-profile-wlan-dot1x] dot1x authentication-method eap
   [AC-dot1x-access-profile-wlan-dot1x] quit

7. Configure an authentication profile named wlan-authentication, apply the 802.1X access profile, and configure a forcible authentication domain.

   [AC] authentication-profile name wlan-authentication
   [AC-authen-profile-wlan-authentication] dot1x-access-profile wlan-dot1x
   [AC-authen-profile-wlan-authentication] access-domain huawei.com dot1x force
   [AC-authen-profile-wlan-authentication] quit

8. Configure the AP to go online.

   # Create an AP group and add the AP to the AP group.

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

   # Create a regulatory domain profile, configure the AC country code in the profile, and apply the profile to the AP group.

   [AC-wlan-view] regulatory-domain-profile name domain1
   [AC-wlan-regulate-domain-domain1] country-code cn
   [AC-wlan-regulate-domain-domain1] quit
   [AC-wlan-view] ap-group name ap-group1
   [AC-wlan-ap-group-ap-group1] regulatory-domain-profile domain1
   Warning: Modifying the country code will clear channel, power and antenna gain configurations of the radio and reset the AP. Continue?[Y/N]:y  
   [AC-wlan-ap-group-ap-group1] quit
   [AC-wlan-view] quit

   # Configure the AC's source interface.

   [AC] capwap source interface vlanif 100

   # Import the AP offline on the AC and add the AP to AP group ap-group1. Assume that the AP's MAC address is 60de-4476-e360. Configure a name for the AP based on the AP's deployment location, so that you can know where the AP is deployed from its name. For example, name the AP area_1 if it is deployed in Area 1.

   

   The default AP authentication mode is MAC address authentication. If the default settings are retained, you do not need to run the ap auth-mode mac-auth command.

   In this example, the AP5030DN is used and has two radios: radio 0 (2.4 GHz radio) and radio 1 (5 GHz radio).

   [AC] wlan
   [AC-wlan-view] ap auth-mode mac-auth
   [AC-wlan-view] ap-id 0 ap-mac 60de-4476-e360
   [AC-wlan-ap-0] ap-name area_1
   [AC-wlan-ap-0] ap-group ap-group1
   Warning: This operation may cause AP reset. If the country code changes, it will clear channel, power and antenna gain configuration s of the radio, Whether to continue? [Y/N]:y  
   [AC-wlan-ap-0] quit

   # After the AP is powered on, run the display ap all command to check the AP state. If the State field is displayed as nor, the AP goes online normally.

   [AC-wlan-view] display ap all
   Total AP information:

   [AC-wlan-ap-group-ap-group1] vap-profile wlan-vap wlan 1 radio 0
   [AC-wlan-ap-group-ap-group1] vap-profile wlan-vap wlan 1 radio 1
   [AC-wlan-ap-group-ap-group1] quit

10. Set channels and power for the AP radios.
    

    Automatic channel and power calibration functions are enabled by default. The manual channel and power configurations take effect only when these two functions are disabled. The channel and power configuration for the AP radios in this example is for reference only. In actual scenarios, configure channels and power for AP radios based on country codes of APs and network planning results.

    # Disable automatic channel and power calibration functions of radio 0, and configure the channel and power for radio 0.

    [AC-wlan-view] ap-id 0
    [AC-wlan-ap-0] radio 0
    [AC-wlan-radio-0/0] calibrate auto-channel-select disable
    [AC-wlan-radio-0/0] calibrate auto-txpower-select disable
    [AC-wlan-radio-0/0] channel 20mhz 6
