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.

When an AP switches its working channel upon detecting radar signals, it randomly selects a channel allowed by the country code. The selected channel may be the same as or adjacent to the working channel of surrounding 5 GHz radios, thereby causing severe interference and poor network access experience. By default, the DFS smart selection function is enabled so that the AP switches to a 5 GHz channel with the minimum interference, preventing 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.

Precautions

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