Example for Configuring Band Steering

Example for Configuring Band Steering

Configuration Process

You need to configure and maintain WLAN features and functions in different profiles. These WLAN profiles include regulatory domain profile, radio profile, VAP profile, AP system profile, AP wired port profile,and WIDS profile. When configuring WLAN services, you need to set related parameters in the WLAN profiles and bind the profiles to the AP group or APs. After that, the configuration is automatically delivered to and takes effect on the RUs. WLAN profiles can reference one another; therefore, you need to know the relationships among the profiles before configuring them. For details about the profile relationships and their basic configuration procedure, see WLAN Service Configuration Procedure.

Networking Requirements

As shown in Figure 18-10, 2.4 GHz and 5 GHz wireless networks are deployed in the conference hall. An RU works on dual frequency bands and directly connects to a central AP. STAs connected to the RU support both 2.4 GHz and 5 GHz frequency bands.

To improve user experience and reduce burden on the 2.4 GHz frequency band, the customer requires that STAs preferentially connect to the 5 GHz frequency band.

For the WLAN access configuration, see Related Topics.

Item

Data

VAP profile
  • Name: wlan-vap
  • Band steering function: enabled
  • Referenced profiles: SSID profile wlan-ssid and security profile wlan-security
RRM profile
  • Name: band-steer

  • Start threshold for load balancing between radios: 15

  • Load difference threshold for load balancing between radios: 25

2G radio profile
  • Name: radio2g
  • Referenced profile: RRM profile band-steer

Configuration Roadmap

Configure the band steering function and proper band steering parameters so that STAs can preferentially access the 5 GHz frequency band.

Configuration Notes

  • Use APs that support both 5 GHz and 2.4 GHz frequency bands and configure the same SSID and security policy on the 5 GHz and 2.4 GHz radios.
  • To allow a STA to preferentially associate with the 5 GHz radio and achieve a better access effect, configure larger power for the 5 GHz radio than the 2.4 GHz radio.
  • Configure port isolation on the interfaces of the device directly connected to RUs. If port isolation is not configured, a large number of unnecessary broadcast packets may be generated in the VLAN, blocking the network and degrading user experience.

Procedure

  1. Check the basic configuration of the WLAN.

    Check Item

    Command

    Data

    Check the AP group to which an RU belongs.

    display ap all

    AP group: ap-group1

    Check all profiles referenced by the AP group.

    display ap-group name ap-group1

    VAP profile: wlan-vap

    Check all profiles referenced by the VAP profile.

    display vap-profile name wlan-vap

    SSID profile: wlan-ssid

  2. Configure the band steering function.

    # Enable the band steering function in the VAP profile wlan-vap. By default, the band steering function is enabled.
    NOTE:

    When band steering is enabled on one radio of an RU, the function takes effect on the SSID of the RU. If different VAP profiles are applied to two radios of the RU, you only need to enable the band steering function in the VAP profile of one radio.

    [AP-wlan-view] vap-profile name wlan-vap
    [AP-wlan-vap-prof-wlan-vap] undo band-steer disable 
    [AP-wlan-vap-prof-wlan-vap] quit
    

    # Create the RRM profile band-steer and configure load balancing between radios in the profile to prevent heavy load on a single radio. The start threshold for load balancing between radios is 15, and the load difference threshold is 25%.

    [AP-wlan-view] rrm-profile name band-steer
    [AP-wlan-rrm-prof-band-steer] band-steer balance start-threshold 15 
    [AP-wlan-rrm-prof-band-steer] band-steer balance gap-threshold 25
    [AP-wlan-rrm-prof-band-steer] quit
    # Create the 2G radio profile radio2g and bind the RRM profile band-steer to the 2G radio profile.
    NOTE:

    If different RRM profiles are bound to the 2G and 5G radio profiles and configured with different band steering parameters, parameters in the 2G radio profile preferentially take effect.

    [AP-wlan-view] radio-2g-profile name radio2g 
    [AP-wlan-radio-2g-prof-radio2g] rrm-profile band-steer
    [AP-wlan-radio-2g-prof-radio2g] quit

    # Bind the 2G radio profile radio2g to the AP group ap-group1.

    [AP-wlan-view] ap-group name ap-group1 
    [AP-wlan-ap-group-ap-group1] radio-2g-profile radio2g
    [AP-wlan-ap-group-ap-group1] quit

  3. Verify the configuration.

    • Run the display vap-profile name wlan-vap command on the central AP. The command output shows that the band steering function is enabled in the VAP profile.

      [AP-wlan-view] display vap-profile name wlan-vap
      --------------------------------------------------------------------------------
      ...
      Band steer                                      : enable                        
      ...
      --------------------------------------------------------------------------------
      
    • Run the display rrm-profile name band-steer command on the central AP to check the band steering configuration.

      [AP-wlan-view] display rrm-profile name band-steer
      ------------------------------------------------------------
      ...
      Band balance start threshold                           : 15
      Band balance gap threshold(%)                          : 25
      ...
      ------------------------------------------------------------  
    • In the conference hall, most STAs connect to the 5 GHz frequency band, and users enjoy good service experience.
