Huawei Wireless Access Controllers V200R003C00 Web Platform Configuration Guide-Example for Configuring Layer 3 Direct Forwarding in Inline Mode

18.2 Example for Configuring Layer 3 Direct Forwarding in Inline Mode

Networking Requirements

As shown in Figure 18-2, the AC connects to the upper layer network, and the AP connects to the AC through the access switch and aggregation switch. The AP communicates with the AC through a Layer 3 network. This networking can cover a large area, simplify network structure, and is mainly applicable to enterprise users who require to effectively manage data packets. The customer must lay out a large number of network cables to deploy a wired network which does not support flexible user access. The deployment of network cables requires huge costs and human resources. The customer wants to deploy a WLAN network, which can reduce deployment costs, improve access flexibility, and enhance network maintainability.

Configuration Roadmap

The configuration roadmap is as follows:

Configure the AP to go online on the AC.
Use the configuration wizard to configure the WLAN service on the AC.
Deliver the WLAN service to the AP and verify the configuration.

NOTE:

During AP deployment, you can manually specify the working channels of the APs according to network planning situations or configure the radio calibration function to enable the APs to automatically select the optimal channels.

If you use the radio calibration function, perform the following steps after delivering configurations to all APs:

Choose WLAN Service > Radio Profile. On the displayed Radio Profile List page, click Refresh and set the channel mode and power mode to auto.
Click Device Management > AP Management > Radio Calibration. The Radio Calibration page is displayed.

In Radio Calibration Settings, set Calibration mode to Manual and click Start. Manual radio calibration is triggered.
APs finish radio calibration one hour after the radio calibration is manually triggered. After that, you can perform either of the configurations:
- (Recommended) change the radio calibration mode to scheduled calibration and configure the APs to perform radio calibration in off-peak hours, for example, between 00:00 am and 06:00 am.
- Manually fix the working channels of APs: set the channel mode and power mode to Fixed mode in the radio profile. If a new AP gets online, repeat step 2.

Procedure

Configure the access switch, aggregation switch, and router.
# Add GE0/0/1 and GE0/0/2 on the access switch to VLAN 10 and VLAN 100 respectively. The default VLAN of GE0/0/1 is VLAN 10.
# Add GE0/0/1 on the aggregation switch to VLAN 10 and VLAN 101, GE0/0/2 to VLAN 101 and VLAN 100, create VLANIF 100, and configure an IP address 192.168.100.2/24 for VLANIF 100.
# Configure an IP address pool for VLANIF 101 on the aggregation switch to assign IP addresses to STAs. The address 192.168.101.2 cannot be assigned to STAs.
# Configure DHCP relay on the aggregation switch and set the IP address 192.168.100.1/24 of VLANIF 100 on the AC as the DHCP server address.
# Configure an IP address 192.168.101.2/24 for GE1/0/0 on Router.
# Configure a static route on the aggregation switch. This example assumes that the destination address is 0.0.0.0/0 and the next hop address is 192.168.101.2.
Configure the AP to go online on the AC.
1. Choose Configuration Wizard > Configuration Wizard > AP Online Configuration Wizard. The AP Online Configuration Wizard page is displayed.
2. Configure Ethernet interfaces.
  # On the Configure Ethernet Interface page, click next to GigabitEthernet0/0/1 to add the interface to VLAN 100 and VLAN 101 in tagged mode.
  
  # Add GigabitEthernet0/0/2 to VLAN 101 in tagged mode.
  # Click Next.
3. Configure virtual interfaces.
  # Click Create on the Configure Virtual Interface page. The Create Virtual Interfacepage is displayed.
  # Configure an IP address 192.168.100.1/24 for VLANIF 100.
  
  # Configure an IP address 192.168.101.1/24 for VLANIF101.
  # Click Next.
4. Configure DHCP.
  # Click Create on the Configure DHCP page. The Create IP Pool page is displayed.
  # Configure a global IP address pool named huawei.
  
  # Click Next.
5. Configure the AC.
6. Confirm the settings.
  On the Confirm Settings page, confirm that the settings are correct and then click Finish.
Configure option parameters for the DHCP server.
# Choose IP Service > DHCP > IP Pool, select the address pool named huawei, and click .
# Set the parameter for Vendor-defined.
Configure a static route.
# Choose IP Service > Route > Static Route Configuration and click Create to create a static route.
Configure the WLAN service.
1. Choose Configuration Wizard > Configuration Wizard > WLAN Configuration Wizard. The WLAN Configuration Wizard page is displayed.
2. Select Common WLAN Service and click Next.
3. Add the AP.
  # Click Create on the Configure AP page. The Create AP page is displayed.
  # Set AP type to AP6010DN-AGN and MAC address to 60de-4476-e360 on the Create AP page to add the AP.
  
  Select the AP and click Next.
4. Configure the radio.
  # Select 2.4 GHz.
  # Create a radio profile named radio. Create a WMM profile named wmm and use the default settings in the profile.
  
  # Click Next.
5. Configure the WLAN service.
  # On the Configure WLAN Service page, click Create to create a service set.
  
  # Create a traffic profile named traffic.
  
  # Create a security profile named security.
  
  # Create an ESS interface.
  
  # Select the created security profile, traffic profile, and ESS interface to complete the service set configuration.
  
  # Click OK and then click Next.
Enable radio calibration to allow APs to automatically select optimal channels.
# Click Device Management > AP Management > Radio Calibration. The Radio Calibrationpage is displayed.

In Radio Calibration Settings, set Calibration mode to Manual and click Start. Manual radio calibration is triggered.
# Click Real-Time Channel And Power List. The real-time channel and power list is displayed. Check the current working channel and power of the radio. Assume that there are three online APs on the AC. The list shows that AP channels have been automatically assigned through the radio calibration function.

# APs finish radio calibration one hour after the radio calibration is manually triggered. Then, set Calibration mode to Periodic and Calibration time to 3:00 am.

# Click Apply. The configuration is complete.
Verify the configuration.
1. The WLAN with the SSID huawei is available for the STA.
2. The STA can associate with the WLAN and obtain an IP address 192.168.101.x/24 and its gateway address is 192.168.101.1.
3. Choose Terminal Management > Terminal Management > STA Management. You can see that the STA goes online successfully and obtains an IP address.
