Configuring Mesh Radio Parameters

Configuring Mesh Radio Parameters

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run wlan

    The WLAN view is displayed.

  3. Enter the radio view.

    • Enter the AP group radio view.
      1. Run the ap-group name group-name command to enter the AP group view.
      2. Run the radio radio-id command to enter the radio view.
    • Enter the AP radio view.
      1. Run the ap-id ap-id, ap-mac ap-mac, or ap-name ap-name command to enter the AP view.
      2. Run the radio radio-id command to enter the radio view.

  4. Run channel { 20mhz | 40mhz-minus | 40mhz-plus | 80mhz | 160mhz } channel or channel 80+80mhz channel1 channel2.

    The working bandwidth and channel are configured for the radio.

    By default, the working bandwidth of a radio is 20 MHz, and no working channel is configured for a radio.

    Radios of different AP nodes on a Mesh link must be configured with the same channel and bandwidth.

    The 80 MHz, 160 MHz, and 80+80 MHz working bandwidths are only supported in the 5G radio view.

    802.11ac APs support the 80 MHz configuration, whereas four-spatial-stream 802.11ac APs allow for the 160 MHz or 80+80 MHz configuration.

    Working channels of radios vary according to countries and regions. To conform to local laws and regulations, you need to configure different working channels under different country codes. You can run the display ap configurable channel { ap-name ap-name | ap-id ap-id } command to check the channels supported by the specified AP.

  5. Run coverage distance distance

    The radio coverage distance parameter is specified.

    By default, the radio coverage distance parameter is 3 (unit: 100 m) for all radios.

    You can configure the radio coverage distance parameter based on distances between APs and the APs automatically adjust the values of slottime, acktimeout, and ctstimeout based on the configured distance parameter to improve data transmission efficiency.

  6. Run frequency 5g

    Radio 0 is configured to work on the 5 GHz frequency band.

    By default, radio 0 works on the 2.4 GHz frequency band, and radio 2 works on the 5 GHz frequency band.

    Among Mesh-capable APs, radio 0 of the AP8130DN and AP8130DN-W support 2.4 GHz and 5 GHz frequency bands but can work on one frequency band at a time. If you configure radio 0 of the AP8130DN and AP8130DN-W to work on the 5 GHz frequency band, the AP8130DN and AP8130DN-W can then work in dual-5G mode.

  7. Run quit

    Return to the AP group view or AP view.

  8. Run quit

    Return to the WLAN view.

  9. Run radio-2g-profile name profile-name or radio-5g-profile name profile-name

    The 2G or 5G radio profile view is displayed.

  10. Run wifi-light signal-strength

    The blinking frequency of the Wireless indicator on the AP is configured to reflect the signal strength.

    By default,
    • If the Mesh function is enabled on the AP, the blinking frequency of the Wireless LED reflects the weakest signal strength of all neighboring APs.
    • If WDS is enabled on an AP, the blinking frequency of the Wireless LED reflects the strength of signals received from a WDS AP.
      • If the AP works in leaf mode, the blinking frequency of the Wireless LED reflects the strength of signals received from a middle AP.
      • If the AP works in middle mode, the blinking frequency of the Wireless LED reflects the strength of signals received from a root AP.
      • If the AP works in root mode, the blinking frequency of the Wireless LED reflects the weakest signal strength of middle APs.
    • If the WDS and Mesh functions are disabled on an AP, the blinking frequency of the Wireless LED reflects the service traffic volume on the radio.

    During installation and commissioning of an AP that has the WDS or Mesh function enabled, you need to adjust AP locations and antenna directions to obtain strong signals. If the blinking frequency of the Wireless LED shows the signal strength, onsite installation personnel can know the signal strength in real time. The wifi-light command allows you to specify the parameter reflected by the blinking frequency of the Wireless LED. For example, you can specify the parameter to signal strength during installation and service traffic volume after installation.

    NOTE:

    This command takes effect only when the AP has the WDS or Mesh function enabled. If the WDS and Mesh functions are disabled on the AP, the Wireless LED always shows service traffic volume.

Follow-up Procedure

In the AP group view or AP view, run the radio-2g-profile profile-name { radio { radio-id | all } } or radio-5g-profile profile-name { radio { id | all } } command to bind the 2.4G or 5G radio profile to the AP radio. Alternatively, you can run the radio-2g-profile profile-name or radio-5g-profile profile-name command in the AP group radio view or AP radio view to bind the 2.4G or 5G radio profile to the AP radio.
