dfs recover-delay

Function

The dfs recover-delay command sets the delay in switching back the DFS channel.

The undo dfs recover-delay command restores the default delay in switching back the DFS channel.

By default, the delay in switching back the DFS channel is 0 minutes. That is, the channel is switched back to the manually planned channel when the legitimate aging time (30 minutes) expires.

Usage Guidelines

When an AP is working on the manually planned channel, if radar signals are detected, the AP switches to a non-radar channel. The AP channel will be switched back to the manually planned channel after the configured switchback delay and legitimate aging time (30 minutes). A proper delay in switching back the DFS channel will prevent frequent channel switchovers.

Example

# Set the delay in switching back the DFS channel to 10 minutes.
