Huawei Wireless Access Controllers V200R003C00 Web Platform Configuration Guide-Example for Configuring Traffic-based Dynamic Load Balancing

Hi, everyone! Today I’m going to introduce you example for configuring traffic-based dynamic load balancing on the AC and AP.

18.12 Example for Configuring Traffic-based Dynamic Load Balancing

Networking Requirements

As shown in Figure 18-12, AP1 and AP2 connecting to the AC are dual-band APs and join AP region 0. STAs in AP region 0 support 2.4 GHz and 5 GHz frequency bands. Both 2.4 GHz and 5 GHz WLANs need to be deployed in AP region 0.

When a large number of STAs access the Internet through the same AP, the AP is heavily loaded, reducing WLAN service quality. The enterprise wants STAs to be balanced on the two APs to prevent one AP from being heavily loaded.

Configuration Roadmap

The configuration roadmap is as follows:

Use the configuration wizard to configure the APs to go online on the AC.
Use the configuration wizard to configure the WLAN service on the AC.
Deliver the WLAN service to the APs.
Configure traffic-based dynamic load balancing.

Procedure

Configure the APs 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 the Ethernet interface.
  
  # On the Configure Ethernet Interface page, click next to GigabitEthernet0/0/1 to add the interface to VLAN 100 in tagged mode.
  
  # Configure GigabitEthernet0/0/2, and add it to VLAN 100 in tagged mode in the same way.
  # 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 an IP address pool for VLANIF 100.
  
  # Configure an IP address pool for VLANIF 101.
  # 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 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 APs.
  
  # 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 AP1.
  
  # Add AP2 in the same way.
  # Select an AP and click Next after the AP status becomes normal.
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, ESS interface, click Advanced, and set Forwarding mode to Tunnel.
  
  # Click OK and then click Next.
6. Confirm the settings.
  # Confirm that the settings are correct, and then click Finish. In the message that is displayed, confirm that the configuration is to be delivered to the AP.
Configure dynamic load balancing.
1. Choose WLAN Service > Load Balancing Group > Dynamic Load Balancing Group. The Dynamic Load Balancing Group page is displayed. Set Dynamic load balancing group function to Enable, Load balancing mode to Traffic mode, Traffic threshold (%) to 25, and Maximum number of association requests to 10.
2. Click Apply to complete the configuration.
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. If a new STA requests to connect to one AP in AP region 0, the AC uses a dynamic load balancing algorithm to determine whether to allow access from the STA. If the load difference between the two APs is larger than 25%, the AC rejects the association request of the STA to the heavily loaded AP. If the STA continues sending association requests to the AP for more than 10 times, the AC allows the STA to associate with the AP.
