(Optional) Setting Air Scan Parameters

(Optional) Setting Air Scan Parameters

Context

When the default air scan profile cannot meet user requirements, you can create a new one and set air scan parameters as required, for example, air scan channel set, air scan period, and air scan interval. The configured air scan profile applies to the radio calibration, smart roaming, WLAN location, and WIDS functions.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run wlan

    The WLAN view is displayed.

  3. Run the air-scan-profile name profile-name command to create an air scan profile and enter the air scan profile view.

    By default, the system provides the air scan profile default.

  4. Run the undo scan-disable command to enable the air scan function.

    By default, the air scan function is enabled.

  5. (Optional) Run the scan-channel-set { country-channel | dca-channel | work-channel } command to configure an air scan channel set.

    By default, an air scan channel set contains all channels supported by the corresponding country code of an AP.

  6. (Optional) Run the scan-period scan-time command to set the air scan period.

    By default, the air scan period is 60 ms.

    NOTE:

    A longer air scan period indicates more collected data and a more accurate data analysis result. However, if the air scan period is set too large, WLAN services are affected. You are advised to use the default value.

  7. (Optional) Run the scan-interval scan-time command to set the air scan interval.

    By default, the air scan interval is 10000 ms.

    NOTE:
    • The air scan interval also applies to radio calibration, smart roaming, WLAN location, and WIDS functions.

    • If the customer has high requirements on real-time data analysis, configure a small air scan interval using the scan-interval command to improve the scan frequency; however, higher scan frequency indicates much larger impact on the services.

  8. Run quit

    Return to the WLAN view.

  9. Enter the radio profile view.

    • When the configured air scan channel set contains only 2.4 GHz channels, run the radio-2g-profile name profile-name command to enter the 2G radio profile.

    • When the configured air scan channel set contains only 5 GHz channels, run the radio-5g-profile name profile-name command to enter the 5G radio profile.

    • When the configured air scan channel set contains both 2.4 GHz and 5 GHz channels, enter the 2G and 5G radio profiles.

    NOTE:

    You can bind the created air scan profile to the current radio profile bound to the AP. To bind the air scan profile to a new radio profile, bind the radio profile to the radio of an AP group or a specific AP first. For details, see Binding a Radio Profile.

  10. Run the air-scan-profile profile-name command to apply the air scan profile.

    By default, the air scan profile default is bound to a radio profile.
