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.

   For AP models that support 80 MHz, 160 MHz, and 80+80 MHz working bandwidths, see Configuration Limitations for Basic WLAN Services in the Configuration-WLAN Service Configuration Guide.

   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.

   On APs supporting radio switching between the 2.4 GHz and 5 GHz frequency bands, some radios support both the two bands. However, such radios can work on one band at a time. You can configure the working frequency band of the AP based on the frequency band of STAs.

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 run 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 APs that have the WDS or Mesh function enabled, you need to adjust WDS or Mesh 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.

    

    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.
