Example for Configuring Layer 2 Direct Forwarding in Inline Mode

Procedure

1. Configure the network devices.
   # Add GE0/0/1 and GE0/0/2 on the access switch to VLAN 100 and VLAN 101. The default VLAN of GE0/0/1 is VLAN 100.

   <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 100 101
   [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 100 101
   [Switch-GigabitEthernet0/0/2] quit

   # Add GE1/0/0 on Router to VLAN 101. Create VLANIF 101 and set its IP address to 10.23.101.2/24.

   <Huawei> system-view
   [Huawei] sysname Router
   [Router] vlan batch 101
   [Router] interface gigabitethernet 1/0/0
   [Router-GigabitEthernet1/0/0] port link-type trunk
   [Router-GigabitEthernet1/0/0] port trunk allow-pass vlan 101
   [Router-GigabitEthernet1/0/0] quit
   [Router] interface vlanif 101
   [Router-Vlanif101] ip address 10.23.101.2 24
   [Router-Vlanif101] quit

2. Configure the AC to communicate with the network devices.

   If the AC and APs are directly connected, set the default VLAN of the interfaces connected to the APs to management VLAN 100.

   # On the AC, add GE0/0/1 to VLAN 100 and VLAN 101, and GE0/0/2 to VLAN 101.

   <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 100 101
   [AC-GigabitEthernet0/0/1] quit
   [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 DHCP servers to assign IP addresses to APs and STAs.
   # On the AC, configure VLANIF 100 and VLANIF 101 to assign IP addresses to APs and STAs, respectively, and configure a default route with the next hop of the address of Router.

   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.

   [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 excluded-ip-address 10.23.101.2
   [AC-Vlanif101] quit
   [AC] ip route-static 0.0.0.0 0.0.0.0 10.23.101.2

4. Configure an AP to go online.
   # Create an AP group to which the APs with the same configuration can be added.

   [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 default
   [AC-wlan-regulate-domain-default] country-code cn
   [AC-wlan-regulate-domain-default] quit
   [AC-wlan-view] ap-group name ap-group1
   [AC-wlan-ap-group-ap-group1] regulatory-domain-profile default
   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.

   In V200R021C00 and later versions, when the CAPWAP source interface or source address is configured, the system checks whether security-related configurations exist, including the PSK for DTLS encryption, PSK for DTLS encryption between ACs, user name and password for logging in to the AP, and password for logging in to the global offline management VAP, the configuration can be successful only when both of them exist. Otherwise, the system prompts you to complete the configuration first.

   [AC] capwap source interface vlanif 100
   Set the DTLS PSK(contains 6-32 plain-text characters, or 48 or 68 cipher-text characters that must be a combination of at least two of the following: lowercase letters a to z, uppercase letters A to Z, digits, and special characters):******
   
   Set the DTLS inter-controller PSK(contains 6-32 plain-text characters, or 48 or 68 cipher-text characters that must be a combination of at least two of the following: lowercase letters a to z, uppercase letters A to Z, digits, and special characters):******
   
   Set the user name for FIT APs(contains 4-31 plain-text characters, which can only include letters, digits and underlines. And the first character must be a letter):admin
   
   Set the password for FIT APs(plain-text password of 8-128 characters or cipher-text password of 48-188 characters that must be a combination of at least three of the following: lowercase letters a to z, uppercase letters A to Z, digits, and special characters):********
   
   Set the global temporary-management psk(contains 8-63 plain-text characters, or 48-108 cipher-text characters that must be a combination of at least two of the following: lowercase letters a to z, uppercase letters A to Z, digits, and special characters):********

   # Enable the function of establishing CAPWAP DTLS sessions in none authentication mode. (V200R021C00 and later versions)

   [AC] capwap dtls no-auth enable

   From V200R021C00, DTLS encryption is enabled for CAPWAP control tunnels on the AC by default. After this function is enabled, an AP will fail to go online when it is added. In this case, you need to enable CAPWAP DTLS non-authentication for the AP so that the AP can obtain a security credential. After the AP goes online, disable this function to prevent unauthorized APs from going online.

   # 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 and radio 1. Radio 0 of the AP5030DN works on the 2.4 GHz frequency band and radio 1 works on the 5 GHz frequency band.

   [AC] undo capwap dtls no-auth enable
   [AC] wlan

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

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

   [AC-wlan-view] security-profile name wlan-net
   [AC-wlan-sec-prof-wlan-net] security wpa-wpa2 psk pass-phrase a1234567 aes
   [AC-wlan-sec-prof-wlan-net] quit

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

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

   # Create VAP profile wlan-net, 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-net
   [AC-wlan-vap-prof-wlan-net] forward-mode direct-forward
   [AC-wlan-vap-prof-wlan-net] service-vlan vlan-id 101
   [AC-wlan-vap-prof-wlan-net] security-profile wlan-net
   [AC-wlan-vap-prof-wlan-net] ssid-profile wlan-net
   [AC-wlan-vap-prof-wlan-net] quit

   # Bind VAP profile wlan-net 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-net wlan 1 radio 0
   [AC-wlan-ap-group-ap-group1] vap-profile wlan-net wlan 1 radio 1
   [AC-wlan-ap-group-ap-group1] quit

6. Set the channels and power for 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 settings of the AP channel and power in this example are for reference only. You need to configure the AP channel and power based on the actual country code and network planning.

   # 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
   Warning: This action may cause service interruption. Continue?[Y/N]y 
   [AC-wlan-radio-0/0] eirp 127
   [AC-wlan-radio-0/0] quit

   # Disable automatic channel and power calibration functions of radio 1, and configure the channel and power for radio 1.

   [AC-wlan-ap-0] radio 1
   [AC-wlan-radio-0/1] calibrate auto-channel-select disable
   [AC-wlan-radio-0/1] calibrate auto-txpower-select disable
   [AC-wlan-radio-0/1] channel 20mhz 149
   Warning: This action may cause service interruption. Continue?[Y/N]y 
   [AC-wlan-radio-0/1] eirp 127
   [AC-wlan-radio-0/1] quit
   [AC-wlan-ap-0] quit

7. Verify the configuration.

   The AC automatically delivers WLAN service configurations to the AP. After the service configuration is complete, run the display vap ssid wlan-net command. If Status in the command output is displayed as ON, the VAPs have been successfully created on AP radios.

   [AC-wlan-view] display vap ssid wlan-net
