Usage Guidelines

When the RU works on a dynamic frequency selection (DFS) channel, a radar detection is performed. The RU automatically switches to another channel because the DFS channel frequency may interfere with the radar frequency.

After the undo channel-switch announcement disable command is run, if the RU channel switches, the RU sends an Action frame to instruct STAs to switch channels after multiple Beacon intervals. The RU also switches the channel after the same intervals. The RU and STAs switch channels at the same time to prevent STA reassociations and ensure rapid service recovery.

The channel switching announcement function must be supported by both the RU and STA.
