Parameters

channel-number: Specifies a channel by its number. The value range for this argument varies by country code and radio mode.

auto: Configures the AP to automatically select a channel.

Usage guidelines

When radar signals are detected on the working channel of a radio, the AP changes its channel, and switches back to the specified channel after 30 minutes. Then the AP starts the quiet timer. If no radar signals are detected within the quiet time, the AP starts to use the channel. If radar signals are detected within the quiet time, the AP changes its channel.

If you manually specify a channel in the range of 36 to 64, whether the 5.1 GHz band can be used outdoors depends on the device region.

·     For outdoor devices that use the 5150 to 5250 Hz band:

¡     China—Not supported.

¡     EU—Not supported.

¡     US—Supported if the maximum effective isotropic radiated power (EIRP) at any elevation angle above 30 degrees does not exceed 125mW and you are to deploy 1000 or fewer devices at a time. To install over 1000 devices at one deployment, contact Federal Communications Commission (FCC) and reduce the total transmit power.

¡     Canada—Not supported.

·     For outdoor devices that use the 5250 to 5350 Hz band:

¡     China—Not supported.

¡     EU—Not supported.

¡     US—Supported if Depth First Search (DFS) is used.

¡     Canada—Supported if Depth First Search (DFS) is used.

Parameters

blacklist: Adds channels to the channel selection blacklist. An AP will not select channels in the blacklist.

whitelist: Adds channels to the channel selection whitelist. An AP will only select channels in the whitelist.

channel-number: Specifies channels by their channel numbers. The value range for this argument varies by country code and radio mode.

all: Specifies all channels in the channel selection blacklist or whitelist.

Usage guidelines

You cannot configure both the channel selection blacklist and whitelist for the same AP.

This command takes effect only on APs operating in auto channel selection mode.

Examples

# Add channels 48, 52, and 56 to the channel selection whitelist.

<Sysname> system-view

network-admin

Parameters

20: Sets the bandwidth mode to 20 MHz.

40: Sets the bandwidth mode to 40 MHz.

80: Sets the bandwidth mode to 80 MHz.

auto-switch: Allows a radio to switch its bandwidth mode between 20 MHz and 40 MHz. This keyword is applicable only to 802.11gn and 802.11gac radios.

160: Sets the bandwidth mode to 160 MHz. Support for this keyword depends on the AP model.

Usage guidelines

This command is applicable only to 802.11n, 802.11ac, 802.11gac, 802.11ax, and 802.11gax radios. When you change the mode of a radio, the default setting of this command for the new radio mode is restored.

The radio uses the specified 40/80/160 MHz bandwidth if adjacent channels can be bound to form a 40/80/160 channel. If adjacent channels cannot form a 40/80/160 channel, the radio uses the next available bandwidth less than the specified one.

For example, the bandwidth mode is set to 80 MHz. The radio uses the 80 MHz bandwidth if adjacent channels that can be bound together exist. If adjacent channels that can be bound to an 80 MHz channel do not exist, but two adjacent channels that can be bound to a 40 MHz channel exist, the 40 MHz bandwidth is used. If no adjacent channels that can be bound together exist, the radio uses the 20 MHz bandwidth.

Examples

# Set the bandwidth mode to 40 MHz.

Parameters

antenna-gain: Specifies the antenna gain in the range of 0 to 20 dBi.

Usage guidelines

This command is applicable only when an AP uses a third-party antenna.

Effective Isotropic Radiated Power (EIRP) is the actual transmit power of an antenna, and it is the sum of the antenna gain and the maximum transmit power of the radio. If the configured antenna gain causes the EIRP to exceed the threshold, the antenna gain configuration fails.

Make sure the antenna gain setting is the same as the gain of the antenna used on the AP.

Changing the radio mode automatically changes the antenna gain.

Parameters

index: Specifies the multicast MCS index in the range of 0 to 76.

Usage guidelines

This command is applicable only to 802.11n, 802.11ac, 802.11gac, 802.11ax, and 802.11gax radios. Changing the radio mode to 802.11a, 802.11b, or 802.11g invalidates the command.

The multicast MCS index takes effect only when the radio associates only with 802.11n, 802.11ac, and 802.11ax clients.

If 802.11a/b/g clients exist, the AP and clients use the 802.11a/b/g multicast rate to send multicast packets.

The multicast MCS index maps to a rate in 20 MHz bandwidth mode regardless of whether the bandwidth mode is 20 MHz or 40 MHz.

Parameters

radio-power: Specifies the maximum transmit power.

Usage guidelines

The transmit power range supported by a radio varies by country code, channel, AP model, radio mode, antenna type, and bandwidth mode. If you change these attributes for a radio after you set the maximum transmit power, the configured maximum transmit power might be out of the supported transmit power range. If this happens, the system automatically adjusts the maximum transmit power to a valid value.

If you enable power lock, the locked power becomes the maximum transmit power.

Usage guidelines

This command is applicable only to 802.11ac, 802.11gac, 802.11ax, and 802.11gax radios. Changing the radio mode to 802.11a, 802.11b, 802.11g, or 802.11n invalidates the command.

TxBF enables an AP to adjust transmitting parameters based on the channel information to focus RF signals on intended clients. This feature improves the RF signal quality.

Multi-user TxBF is part of 802.11ac Wave2. Multi-user TxBF enables an AP to focus different RF signals on their intended clients to reduce interference and transmission delay. This improves traffic throughput and bandwidth usage. Multi-user TxBF is applicable to WLANs that have a large number of clients and require high bandwidth usage and low transmission delay.

Multi-user TxBF takes effect only when single-user TxBF is enabled.

As a best practice, do not modify the default MIMO settings for an AP enabled with multi-user TxBF.

Examples

# Enable multi-user TxBF.

Parameters

cts-to-self: Specifies the CTS-to-self mode.

rts-cts: Specifies the RTS/CTS mode.

Usage guidelines

You can specify either of the following collision avoidance modes for an AP:

·     RTS/CTS—An AP sends an RTS packet to a client before sending data to the client. After receiving the RTS packet, the client sends a CTS packet to the AP. The AP begins to send data after receiving the CTS packet, and other devices that detect the RTS or CTS packet do not send data within a specific time period.

·     CTS-to-self—An AP sends a CTS packet with its own MAC address as the destination MAC address before sending data to a client. After receiving the CTS-to-self packet, the AP begins to send data, and other devices that detect the CTS-to-self packet do not send data within a specific time period.

Examples

# Specify the RTS/CTS mode.

Parameters

disabled: Specifies rates that cannot be used by an AP.

mandatory: Specifies rates that the clients must support to associate with an AP.

multicast: Specifies the rate at which an AP multicasts packets. The multicast rate must be selected from the mandatory rates.

supported: Specifies rates that an AP supports. After a client associates with an AP, the client can select a higher or lower rate from the supported rates to communicate with the AP.

auto: Automatically selects a mandatory rate as the multicast rate.

rate-value: Specifies the rate value in Mbps. You can set multiple rates and separate them by spaces. The available values for this argument are as follows:

·     802.11a/802.11an/802.11ac/802.11ax—6, 9, 12, 18, 24, 36, 48, and 54.

·     802.11b—1, 2, 5.5, and 11.

·     802.11g/802.11gn/802.11gac/802.11gax—1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, and 54.

Usage guidelines

The mandatory rates and multicast rate cannot be null. When there is only one mandatory rate, you cannot specify the mandatory rate as a supported rate or prohibited rate.

Examples

# Set the mandatory rates to 6 Mbps, 12 Mbps, and 24 Mbps.
