Function

(AP group radio view) The channel command configures the working bandwidth and channel for all specified radios in an AP group.

(AP group radio view) The undo channel command restores the default working bandwidth and channel for all specified radios in an AP group.

(AP radio view) The channel command configures the working bandwidth and channel for an AP radio.

(AP radio view) The undo channel command cancels the configuration of the working bandwidth and channel on an AP radio. The working bandwidth and channel on the AP radio are then determined by those configured in the AP group radio view.

By default, the working bandwidth of a radio is 20 MHz, and no working channel is configured for a radio.

You can run the display ap config-info command to check the channel in use on a radio.

Format

channel { 20mhz | 40mhz-minus | 40mhz-plus | 80mhz } channel

Parameters

Parameter

Description

Value

20mhz

Sets the working bandwidth of a radio to 20 MHz.

-

40mhz-minus

Sets the working bandwidth of a radio to 40 MHz Minus.

-

40mhz-plus

Sets the working bandwidth of a radio to 40 MHz Plus.

-

80mhz

Sets the working bandwidth of a radio to 80 MHz.

The 80 MHz working bandwidth is only supported in the 5G radio view.

-

channel

Specifies the working channel for a radio. The channel is selected based on the country code and radio mode.

The parameter is an enumeration value. The value range is determined according to the country code and radio mode.

Usage Guidelines

Usage Scenario

Different radios use different channels. Channels for radios also vary in different countries and regions. Select channels based on the actual situations.

Precautions

The configured channel parameters must match the radio frequency band. For details about mappings between channel parameters and frequency bands, see Country Codes & Channels Compliance.

The channels you configure must be supported by the terminals; otherwise, the terminals cannot discover wireless signals. For example, when the country code is set to China, 5 GHz channels 36, 40, 44, 48, 52, 56, 60, and 64 can be configured. However, most terminals do not support these channels currently. If these channels are configured, the terminals cannot discover wireless signals. In this case, you can configure 5 GHz channels 149, 153, 157, 161, and 165, which are supported by the terminals.

If an RU detects radar signals on a channel, the channel cannot be configured as the radio channel of the RU in 30 minutes. However, the channel can be configured as the radio channel of other RUs not detecting radar signals on it.

If an AP works in dual-5G mode, the channels of the two 5G radios must be separated by at least one channel.

For example, a country supports 40 MHz 5G channels 36, 44, 52, and 60. When deploying 5G radio channels, if one radio is deployed on channel 36, it is recommended that the other radio be deployed on channel 52 or 60. Channel 44 is not recommended in this case.

The configuration in the AP radio view has a higher priority than that in the AP group radio view.

Example

# Set the working bandwidth to 20 MHz and channel to 6 for radio 0 of AP 1.
<Huawei> system-view
[Huawei] wlan 
[Huawei-wlan-view] ap-id 1
[Huawei-wlan-ap-1] radio 0
[Huawei-wlan-radio-1/0] channel 20mhz 6
