Configure Smart RF Select Shutdown Settings

Configuring auto-shutdown of select 2.4 GHz radios—in dual-band networks—maintains CCI levels within specified limits. When Select Shutdown is 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 deactivated radios are activated until the deployment average CCI reaches acceptable levels.

Use this procedure to activate auto-shutdown of 2.4 GHz access point radios causing interference within the Smart RF monitored network.

Go to Policies > Smart RF <select a Smart RF policy> Select Shutdown.

Configure auto-shutdown parameters as described in Select Shutdown Parameters.

Table 1. Select Shutdown Parameters
Parameter	Description
CCI High Threshold	Specify the maximum CCI threshold from -85 dBm to -55 dBm. If the threshold is not specified, the system uses the default value as the upper limit for the deployment average CCI range. The default value is -80 dBm.
CCI Low Threshold	Specify the minimum CCI threshold from -85 dBm to -55 dBm. If the threshold is not specified, the system uses the default value as the lower limit for the deployment average CCI range. The default value is -100 dBm.
Frequency	Set 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 events. Specify a Frequency in the range 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 to 1000. The default value is 10.
