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.
