Function

The channel-switch announcement disable command disables an AP from sending an announcement when the channel is switched.

The undo channel-switch announcement disable command enables an AP to send an announcement when the channel is switched.

By default, an AP sends an announcement when the channel is switched.

Parameters

None

Views

2G radio profile view, 5G radio profile view

Default Level

2: Configuration level

Usage Guidelines

When the AP works on a Depth First Select (DFS) channel, a radar detection is performed. The AP 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 AP channel switches, the AP sends an Action frame to instruct STAs to switch channels after multiple Beacon intervals. The AP also switches the channel after the same intervals. The AP and STAs switch channels at the same time to prevent STA reassociations and ensure rapid service recovery.

NOTE:

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

Example

# Disable the AP from sending an announcement after the channel is switched.

<HUAWEI> system-view
[HUAWEI] wlan 
[HUAWEI-wlan-view] radio-2g-profile name default
[HUAWEI-wlan-radio-2g-prof-default] channel-switch announcement disable
