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

Use this command to enable select-shutdown and configure the maximum and minimum CCI thresholds.

Supported in the following platforms:

select-shutdown Enables auto-shutdown of selected 2.4 GHz radios to maintain the deployment average CCI levels within a specified range
cci-high-threshold <-85--55> Optional. Configures the maximum CCI threshold
  • <-85--55> – Specify a value from -85 - -55 dBm. The default value is -80 dBm.
Note: If not specified, the system uses the default value as the upper limit.
cci-low-threshold <-100--55> Optional. Configures the minimum CCI threshold
  • <-100--55> – Specify a value from -100 - -55 dBm. The default value is -100 dBm.
Note: If not specified, the system uses the default value as the lower limit.
frequency <0-3600> Configures 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.
  • <0-3600> – Specify the frequency from 0 - 3600 minutes. The default is 60 minutes.
frequency-limiter <1-1000> Configures the minimum multiple of Interference Recovery frequency that the select-shutdown frequency can be set to
  • <1-100> – Specify a value from 1 - 1000. The default value is 15.
