Example for Configuring Service Holding upon CAPWAP Link Disconnection

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 the switch and AC to enable the AC to communicate with the APs.

   # Create VLAN100 (management VLAN) and VLAN101 (service VLAN) on the switch. Set the link type of GE0/0/1 that connects the switch to the APs to trunk and PVID of the interface to 100, and configure the interface to allow packets of VLAN100 and VLAN101 to pass. Set the link type of GE0/0/2 on the switch to trunk, and configure the interface to allow packets of VLAN100 to pass.

   <HUAWEI> system-view
   [HUAWEI] sysname Switch
   [Switch] vlan batch 100 101
   [Switch] interface gigabitethernet 0/0/1
   [Switch-GigabitEthernet0/0/1] port link-type trunk
   [Switch-GigabitEthernet0/0/1] port trunk pvid vlan 100
   [Switch-GigabitEthernet0/0/1] port trunk allow-pass vlan 100 to 101
   [Switch-GigabitEthernet0/0/1] port-isolate enable
   [Switch-GigabitEthernet0/0/1] quit
   [Switch] interface gigabitethernet 0/0/2
   [Switch-GigabitEthernet0/0/2] port link-type trunk
   [Switch-GigabitEthernet0/0/2] port trunk allow-pass vlan 100
   [Switch-GigabitEthernet0/0/2] quit

   # Add GE0/0/1 that connects the AC to the switch to VLAN100.

   <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 allow-pass vlan 100
   [AC-GigabitEthernet0/0/1] quit

3. Configure the DHCP function on the switch to allocate IP addresses to APs and 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 VLANIF100 to use the interface address pool to allocate IP addresses to APs.

   [Switch] dhcp enable
   [Switch] interface vlanif 100
   [Switch-Vlanif100] ip address 10.1.1.1 255.255.255.0
   [Switch-Vlanif100] dhcp select interface
   [Switch-Vlanif100] dhcp server excluded-ip-address 10.1.1.2
   [Switch-Vlanif100] quit

   # Configure VLANIF101 to use the interface address pool to allocate IP addresses to STAs.

   [Switch] interface vlanif 101
   [Switch-Vlanif101] ip address 10.1.2.1 255.255.255.0
   [Switch-Vlanif101] dhcp select interface
   [Switch-Vlanif101] quit

4. 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 domain
   [AC-wlan-regulate-domain-domain] country-code cn
   [AC-wlan-regulate-domain-domain] quit
   [AC-wlan-view] ap-group name ap-group1
   [AC-wlan-ap-group-ap-group1] regulatory-domain-profile domain
   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] interface vlanif 100
   [AC-Vlanif100] ip address 10.1.1.2 255.255.255.0
   [AC-Vlanif100] quit
   [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:
   nor  : normal          [1]
   -------------------------------------------------------------------------------------
   ID   MAC            Name   Group     IP            Type            State STA Uptime
   -------------------------------------------------------------------------------------
   0    60de-4476-e360 area_1 ap-group1 10.1.1.254    AP5030DN       nor   0   10S
   -------------------------------------------------------------------------------------
   Total: 1

5. Configure WLAN service parameters.
   # Create security profile wlan-security and set the security policy in the profile.

   

   In this example, the security policy is set to WPA2+PSK+AES and password to a1234567. In actual situations, the security policy must be configured according to service requirements.

   [AC-wlan-view] security-profile name wlan-security
   [AC-wlan-sec-prof-wlan-security] security wpa2 psk pass-phrase a1234567 aes
   [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 the AP system profile wlan-system and configure the service holding function.

   [AC-wlan-view] ap-system-profile name wlan-system
   [AC-wlan-ap-system-prof-wlan-system] keep-service enable
   [AC-wlan-ap-system-prof-wlan-system] quit

   # Create VAP profile wlan-vap, set the data forwarding mode and service VLAN, and apply the security profile and SSID profile to the VAP profile.

   [AC-wlan-view] vap-profile name wlan-vap
   [AC-wlan-vap-prof-wlan-vap] forward-mode direct-forward
   [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] quit

   # Bind the AP system profile and VAP profile to the AP group and apply the VAP profile to radio 0 and radio 1 of the AP.

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

6. Verify the configuration.

   The WLAN with SSID wlan-net is available for STAs connected to the AP, and these STAs can connect to the WLAN without authentication. If the AC is powered off, service data forwarding for wireless users in area A is not affected.
