Configuring Band Steering

Configuring Band Steering

Pre-configuration Tasks

The band steering function enables an AP to steer STAs to the 5 GHz radio first, which reduces traffic load and interference on the 2.4 GHz radio and improves user experience.

Before configuring band steering, complete the following tasks:

Background

NOTE:

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.

Single-radio devices do not support the band steering function.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    wlan

    The WLAN view is displayed.

  3. Run:

    vap-profile name profile-name

    A VAP profile is created and the VAP profile view is displayed.

  4. Run:

    undo band-steer disable

    The band steering function is enabled.

    By default, the band steering function is enabled.

  5. Run:

    quit

    Return to the WLAN view.

  6. (Optional) Configure band steering parameters.
    1. Run the rrm-profile name profile-name command to create an RRM profile and enter the RRM profile view.
    2. Run the band-steer balance start-threshold start-threshold command to set the start threshold for load balancing between radios.

      By default, the start threshold for load balancing between radios is 10.

    3. Run the band-steer balance gap-threshold gap-threshold command to set the load difference threshold for load balancing between radios.

      By default, the load difference threshold for load balancing between radios is 20%.

    4. Run the band-steer snr-threshold snr-threshold command to configure a start SNR threshold for triggering 5G-prior access.

      The default start SNR threshold for triggering 5G-prior access is 20 dB.

    5. Run the band-steer deny-threshold deny-threshold command to set the maximum number of times an AP rejects association requests of a STA for band steering.

      By default, the maximum number of rejections is 2.

    6. Run the band-steer client-band-expire probe-counters command to set the aging condition for terminal band information.

      By default, band information of a terminal will be aged out under conditions that an AP has consecutively received Probe frames of the terminal more than 35 times from the same frequency band.

  7. Run:

    quit

    Return to the WLAN view.

  8. Bind the radio profile and VAP profile to a radio interface.
    1. Run the quit command to return to the system view.
    2. Run the interface wlan-radio wlan-radio-number command to enter the WLAN-Radio interface view.
    3. Run the vap-profile profile-name wlan wlan-id command to bind the VAP profile to the WLAN-Radio interface.

Verifying the Configuration

  • Run the display vap-profile name profile-name command to check the status of the band steering function.
  • Run the display rrm-profile name profile-name command to check settings of band steering parameters.
  • Run the display radio-2g-profile name profile-name command to check the RRM profile referenced by a 2G radio profile.
  • Run the display radio-5g-profile name profile-name command to check the RRM profile referenced by a 5G radio profile.
