Procedure

1. Configure the AC to enable exchange of CAPWAP packets between the AP and AC.

   # Add AC interface GE0/0/1 to VLAN 100 (management VLAN).

   In this example, tunnel forwarding is used to transmit service data. If direct forwarding is used, configure port isolation on GE0/0/1 that connects the AC to the AP. If port isolation is not configured, a large number of broadcast packets will be transmitted over the VLAN or WLAN users on different APs will be able to directly communicate at Layer 2.

   In tunnel forwarding mode, the management VLAN and service VLAN cannot be the same.

   <HUAWEI> system-view
   [HUAWEI] sysname AC
   [AC] vlan batch 100 101
   [AC] interface gigabitethernet 0/0/1
   [AC-GigabitEthernet0/0/1] port link-type trunk
   [AC-GigabitEthernet0/0/1] port trunk pvid vlan 100
   [AC-GigabitEthernet0/0/1] port trunk allow-pass vlan 100
   [AC-GigabitEthernet0/0/1] quit
   [AC] interface gigabitethernet 0/0/3

2. Configure the AC to communicate with upper-layer network devices.

   # Add GE0/0/2 that connects the AC to the upper-layer device to VLAN 101 (service VLAN).

   [AC] interface gigabitethernet 0/0/2
   [AC-GigabitEthernet0/0/2] port link-type trunk
   [AC-GigabitEthernet0/0/2] port trunk allow-pass vlan 101
   [AC-GigabitEthernet0/0/2] quit

3. Configure the AC to function as the DHCP server to assign IP addresses to the AP and STAs.

   # Configure the AC as the DHCP server to assign an IP address to the AP from the IP address pool on VLANIF 100, and assign IP addresses to STAs from the IP address pool on VLANIF 101.

   [AC] dhcp enable
   [AC] interface vlanif 100
   [AC-Vlanif100] ip address 10.23.100.1 24
   [AC-Vlanif100] dhcp select interface
   [AC-Vlanif100] quit
   [AC] interface vlanif 101
   [AC-Vlanif101] ip address 10.23.101.1 24
   [AC-Vlanif101] dhcp select interface
   [AC-Vlanif101] dhcp server dns-list 10.23.200.2
   [AC-Vlanif101] quit

4. Configure a route from the AC to the server area (Assume that the IP address of the upper-layer device connected to the AC is 10.23.101.2).

   [AC] ip route-static 10.23.200.0 255.255.255.0 10.23.101.2

5. 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: This configuration change will clear the channel and power configurations of radios, and may restart APs. 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 APs offline on the AC and add the APs to AP group ap-group1. 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. This example assumes that the AP's MAC address is 00e0-fc76-e360 and the AP is deployed in area 1. Name the AP 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.

   [AC] wlan
   [AC-wlan-view] ap auth-mode mac-auth
   [AC-wlan-view] ap-id 0 ap-mac 00e0-fc76-e360
   [AC-wlan-ap-0] ap-name area_1
   [AC-wlan-ap-0] ap-group ap-group1
   Warning: This operation may cause AP to go offline and then online. If the country code changes, it will clear channel, power and antenna gain configurations of the radio, Whether to continue? [Y/N]:y  
   [AC-wlan-ap-0] quit
   [AC-wlan-view] quit

   # After the AP is powered on, run the display ap all command to check the AP state. If the State field displays nor, the AP has gone online.

   [AC] display ap all
   Total AP information: 
   nor  : normal          [1] 
   ExtraInfo : Extra information 
   P    : insufficient power supply

   --------------------------------------------------------------------------------------------------
   Total: 11

6. Configure a RADIUS server template, and a RADIUS authentication scheme.

   Ensure that the RADIUS server IP address, port number, and shared key are configured correctly and are the same as those on the RADIUS server.

   # Configure a RADIUS server template.

   [AC] radius-server template radius_huawei
   [AC-radius-radius_huawei] radius-server authentication 10.23.200.1 1812
   [AC-radius-radius_huawei] radius-server accounting 10.23.200.1 1813
   [AC-radius-radius_huawei] radius-server shared-key cipher YsHsjx_202206

   # Modifying the Value of a RADIUS Attribute.

   [AP-radius-radius_huawei] radius-server attribute translate
   [AP-radius-radius_huawei] radius-attribute set Framed-MTU 1000
   [AP-radius-radius_huawei] quit

   When the Access-Challenge packet sent by the RADIUS server contains EAP information longer than 1200 bytes, the terminal may fail to receive the EAP Request/Challenge packet. In this case, you can run this command to set attribute-name to Framed-MTU and reduce the value of the Framed-MTU attribute in the authentication request packet sent by the device to the RADIUS server. The default value of the Framed-MTU attribute is 1500. You can change it to 1000.

   # 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
   [AC-aaa] quit

   # Configure a RADIUS accounting scheme.

   [AC-aaa] accounting-scheme scheme1
   [AC-aaa-accounting-scheme1] accounting-mode radius
   [AC-aaa-accounting-scheme1] accounting realtime 15
   [AC-aaa-accounting-scheme1] quit
   [AC-aaa] quit

   • In this example, the device is connected to the Agile Controller-Campus. The accounting function is not implemented for accounting purposes, and is used to maintain terminal online information through accounting packets.

   • The accounting realtime command sets the real-time accounting interval. A shorter real-time accounting interval requires higher performance of the device and RADIUS server. Set the real-time accounting interval based on the user quantity.

   User Quantity	Real-Time Accounting Interval
   1-99	3 minutes
   100-499	6 minutes
   500-999	12 minutes
   ≥ 1000	≥ 15 minutes

7. Configure a URL template.

   [AC] url-template name url1
   [AC-url-template-url1] url https://10.23.200.1:8445/portal
   [AC-url-template-url1] url-parameter login-url ac_url https://10.23.101.1:8443
   [AC-url-template-url1] quit

   The login-url parameter is used by terminals to send account information to the device. If a Portal server does not support the login URL setting, you need to run the url-parameter command with the login-url parameter specified, so that terminals can send the login URL to the Portal server. In the URL specified by the login-url parameter, the IP address is the AC's local IP address (permitted in the authentication-free rule profile to ensure Layer 3 reachability between terminals and the AC), and the port number is that specified using the portal web-authen-server https command (8443 by default).

8. Configure the HTTPS protocol for Portal authentication.

   If the HTTPS protocol is used for Portal authentication, you need to configure an SSL policy.

   [AC] ssl policy huawei type server
   [AC-ssl-policy-huawei] pki-realm default
   [AC-ssl-policy-huawei] quit
   [AC] http secure-server ssl-policy huawei
   [AC] portal web-authen-server https ssl-policy huawei  
   [AC] portal web-authen-server server-source all-interface   //In V200R021C00 and later versions, you must use the portal web-authen-server server-source command to configure the local gateway address used by the device to receive and respond to the packets sent by the user terminals. Otherwise, the Portal interconnection function cannot be used.
   [AC] web-auth-server abc
   [AC-web-auth-server-abc] protocol http
   [AC-web-auth-server-abc] quit

9. Configure a Portal server template.

   Ensure that the Portal server IP address, URL address, and port number, are configured correctly and are the same as those on the Portal server.

   [AC] web-auth-server abc  
   [AC-web-auth-server-abc] server-ip 10.23.200.1 10.23.101.1
   [AC-web-auth-server-abc] url-template url1
   [AC-web-auth-server-abc] quit

10. Configure the Portal access profile portal1 and configure Layer 2 Portal authentication.

    [AC] portal-access-profile name portal1
    [AC-portal-access-profile-portal1] web-auth-server abc direct
    [AC-portal-access-profile-portal1] quit

11. Configure an authentication-free rule profile.

    [AC] free-rule-template name default_free_rule
    [AC-free-rule-default_free_rule] free-rule 1 destination ip 10.23.200.2 mask 24
    [AC-free-rule-default_free_rule] free-rule 2 destination ip 10.23.101.1 mask 24
    [AC-free-rule-default_free_rule] quit

12. Configure the authentication profile p1.

    [AC] authentication-profile name p1
    [AC-authentication-profile-p1] portal-access-profile portal1
    [AC-authentication-profile-p1] free-rule-template default_free_rule
    [AC-authentication-profile-p1] authentication-scheme radius_huawei
    [AC-authentication-profile-p1] accounting-scheme scheme1
    [AC-authentication-profile-p1] radius-server radius_huawei
    [AC-authentication-profile-p1] quit

13. Configure WLAN service parameters.

    # Create security profile wlan-security and set the security policy in the profile.

    [AC] wlan
    [AC-wlan-view] security-profile name wlan-security
    [AC-wlan-sec-prof-wlan-security] security open
    [AC-wlan-sec-prof-wlan-security] quit

    # Create SSID profile wlan-ssid and set the SSID name to wlan-net.

    [AC-wlan-view] ssid-profile name wlan-ssid
    [AC-wlan-ssid-prof-wlan-ssid] ssid wlan-net
    [AC-wlan-ssid-prof-wlan-ssid] quit

    # Create VAP profile wlan-vap, configure the data forwarding mode and service VLANs, and apply the security profile, SSID profile, and authentication profile to the VAP profile.

    [AC-wlan-view] vap-profile name wlan-vap
    [AC-wlan-vap-prof-wlan-vap] forward-mode tunnel
    [AC-wlan-vap-prof-wlan-vap] service-vlan vlan-id 101
    [AC-wlan-vap-prof-wlan-vap] security-profile wlan-security
    [AC-wlan-vap-prof-wlan-vap] ssid-profile wlan-ssid
    [AC-wlan-vap-prof-wlan-vap] authentication-profile p1
    [AC-wlan-vap-prof-wlan-vap] quit

    # Bind VAP profile wlan-vap to the AP group and apply the profile to radio 0 and radio 1 of the AP.

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

14. Verify the configuration.

    • The WLAN with the SSID wlan-net is available for STAs after the configuration is complete.

    • The STAs obtain IP addresses when they successfully associate with the WLAN.
    • When a user opens the browser and attempts to access the network, the user is automatically redirected to the authentication page provided by the Portal server. After entering the correct user name and password on the page, the user can access the network.
