Configuring Smart RF Select Shutdown Settings

To enable Smart RF select and shutdown 2.4 GHz APs causing interference:

  1. Select Select Shutdown,
    Click to expand in new window
    Smart RF Configuration - Select Shutdown screen
  2. Configure the following parameters that will maintain CCI (co-channel interference) levels within specified limits.
    Enable

    Select to enable auto-shutdown of radios causing interference within the Smart RF monitored network.

    Auto-shutdown of select 2.4 GHz radios, in dual-band networks, maintains CCI levels within specified limits. When enabled, Smart-RF monitors CCI levels to ensure that the deployment average CCI remains within specified minimum and maximum limits. If the deployment average CCI is found to exceed the maximum threshold, 2.4 GHz radios, causing neighbor interference, are shut down one-by-one until the deployment average CCI falls below the specified maximum threshold. The reverse process occurs when the deployment average CCI falls below the minimum threshold. In this scenario, previously disabled radios are enabled until the deployment average CCI reaches acceptable levels.

    Note: This feature is enabled by default.
    CCI High Threshold Specify the maximum CCI threshold from -85 to -55 dBm. The default value is -80 dBm.
    Note: If not specified, the system uses the default value as the upper limit for the deployment average CCI range.
    CCI Low Threshold Specify the minimum CCI threshold from -85 to -55 dBm. The default value is -100 dBm.
    Note: If not specified, the system uses the default value as the lower limit for the deployment average CCI range.
    Frequency Configure the interval, in minutes, at which 2.4 GHz radios are selected for shut down. when the deployment average CCI exceeds the specified maximum threshold, Smart RF shuts down 2.4 GHz radios until the CCI reaches acceptable levels. Use this option, to configure the interval between successive radio shut down.

    Specify the frequency from 0 - 3600 minutes. The default is 60 minutes.

    Frequency Limiter Configure the minimum multiple of Interference Recovery frequency that the select-shutdown frequency can be set to.

    Specify a value from 1 - 1000. The default value is 15.

  3. Click OK to update the Smart RF Select Shutdown settings for this policy.
    Click Reset to revert to the last saved configuration.
