Usage Guidelines

Usage Scenario

After the DFS smart selection function is enabled, an AP working on the 5 GHz band detects radar signals. Upon detecting radar channels, the AP automatically switches to another channel to prevent radar interference.

The switched-to channel is a random non-radar channel and therefore may be the same as or close to the channel of surrounding 5 GHz radios, leading to severe interference and poor user experience. The DFS smart selection function is enabled by default to adjust the 5 GHz channel of an AP to one with the least interference.

After the dfs smart-selection disable command is executed, the DFS smart selection function is disabled, affecting user experience. Configure this function as required.


The DFS smart selection function is valid only when the air scan is enabled.
