NOTE: · Support for the 6 GHz band depends on the AP model and local regulations. · Some tri-band APs support all three radios operating in the 5 GHz band (with radio 1 in 5.15 GHz to 5.35 GHz, radio 2 in 5.47 GHz to 5.85 GHz, and radio 3 in 5.15 GHz to 5.35 GHz or 5.47 GHz to 5.85 GHz). In this case, radio 3 is used only for scanning and is not recommended for service configuration. |

Usage guidelines
This command takes effect only on 802.11ax radios and radios of higher standards. Changing the radio mode to 802.11a/b/g or a lower one removes the configuration.
BSS coloring enables the system to assign a color to each BSS and include the color ID in data packets for clients to identify if a packet comes from the associated AP. To avoid conflicts, clients that detect an 802.11ax data packet with the same color as its associated BSS will postpone transmission.
Enabling BSS coloring in a high density environment can improve system performance and channel usage.
Examples
# Enable BSS coloring.

Predefined user roles
network-admin
Parameters
channel-number: Specifies a channel by its number. The value range for this argument varies by region 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.
Examples
# Specify channel 6 as the working channel.
<Sysname> system-view
[Sysname] interface wlan-radio 1/0/2
[Sysname-WLAN-Radio1/0/2] channel 6
channel band-width
Use channel band-width to set the bandwidth mode.
Use undo channel band-width to restore the default.
Syntax
channel band-width { 20 | 40 [ auto-switch ] | 80 | 160 | 320 }
undo channel band-width
Default
The bandwidth mode is 80 MHz for 802.11eax radios, 80 MHz for 802.11be radios, 160 MHz for 802.11eax radios, 80 MHz for 802.11abe radios, 80 MHz for 802.11ax radios, 20 MHz for 802.11gbe radios, 20 MHz for 802.11gax radios, 80 MHz for 802.11ac radios, 40 MHz for 802.11an radios, and 20 MHz for 802.11gn radios. The default bandwidth mode for 802.11be radios varies by device model.

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 802.11gax radios.
160: Sets the bandwidth mode to 160 MHz. Support for this keyword depends on the AP model.
320: Sets the bandwidth mode to 320 MHz. Support for this keyword depends on the AP model.
Usage guidelines
This command is applicable only to the following radio types: 802.11n, 802.11ac, 802.11ax, and 802.11gax 802.11eax, 802.11be, 802.11abe, and 802.11gbe. 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 40/80/160/320 MHz bandwidth if adjacent channels can be bound to form a 40/80/160/320 channel. If adjacent channels cannot form a 40/80/160/320 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.
If the working channel is specified and the actual bandwidth is 160 MHz or 320 MHz, the device automatically selects a secondary channel.
Examples
# Set the bandwidth mode to 40 MHz.

Parameters
radio-power: Specifies the maximum transmit power. The value range depends on the region code, channel, AP model, radio mode, antenna type, and bandwidth.
Usage guidelines
The transmit power range supported by a radio varies by region 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.

Usage guidelines
Operating mechanism
Multiple Resource Unit (MRU) is a technology that increases the spectral resource usage rate, mainly used in multi-user scenarios.
In Wi-Fi6, each user can only use one RU. In Wi-Fi7, the concept of MRU is introduced to allow a single user to use multiple RUs. As shown in Figure 1, under the same bandwidth, MRU allows a single client to occupy multiple RUs simultaneously when data is being transmitted to two users at the same time. This improves spectral resource usage and reduces latency. In Wi-Fi 6, a single client can only use the single RU resource allocated to it, resulting in a waste of spectral resources.
Restrictions and guidelines
This feature takes effect only on 802.11be, 802.11gbe, and 802.11abe radios. Changing the radio mode to another mode cancels the configuration.
Examples
# Enable MRU.

Usage guidelines
This command is applicable only to 802.11ac radios and radios of higher standards. Changing the radio mode to 802.11a, 802.11b, 802.11g, or 802.11n removes the configuration.
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.

# Enable multi-user TxBF.

Parameters
static: Specifies static preamble puncturing.
Usage guidelines
Operating mechanism
The preamble puncturing technology enables data transmission using discontinuous channels to improve channel utilization efficiency. It is mainly used in scenarios with channel interference.
Without preamble puncturing, as shown in Figure 2, if the bandwidth mode is 80 MHz and interference is encountered on channel 56, the system uses the 20 MHz bandwidth mode instead for transmission. With preamble puncturing enabled, as shown in Figure 3, the interfered portion (channel 56) is punctured and shielded, and the remaining channels 52, 60, and 64 are bundled together for information transmission. Although the AP is still working in the 80 MHz bandwidth mode, the interfered channel is put in Null state (idle state) in actual transmission.
Preamble static puncturing refers to the software designating the puncturing positions based on the bandwidth mode and the position of the primary channel.
Figure 2 Without preamble puncturing
Figure 3 With preamble puncturing
Restrictions and guidelines
Preamble puncturing takes effect only when the bandwidth mode is 80 MHz or higher.
This feature takes effect only on 802.11be and 802.11abe radios. Changing the radio mode to another mode cancels the configuration.
Examples
# Enable preamble puncturing.

Usage guidelines
Radar avoidance enables a radio to change its working channel or keep silent when radar signals are detected on the working channel, avoiding interference on radars. After 30 minutes, the radio switches back to the previous working channel or restarts transmission. If radar signals can still be detected, the radio changes its working channel or keeps silent again.
With this feature disabled, radios continue to transmit or receive traffic on the working channels even if radar signals are detected on the channels.
Disable radar avoidance only when you perform device debugging.

Usage guidelines
TWT negotiation enables clients and APs to exchange data packets only in service periods and schedules client hibernation to reduce client power consumption and wireless resource competition.
With TWT negotiation enabled, clients send negotiation requests that carry the service period, TWT interval, and first wake time (calculated by clients) to APs. Upon receiving such a request, an AP sends a response. Then, the clients wake up as scheduled and wait for trigger frames from that AP. Upon receiving a trigger frame, clients enter a service period and start to exchange data packets with that AP. When a service period expires, clients enter hibernation mode even if data packet exchange is not finished.
A radio can provide the TWT service to a maximum of eight clients. After responding to the TWT negotiation requests of eight clients, the radio rejects the requests from the other clients.
This feature takes effect only on 802.11ax and 802.11gax radios. Changing the radio mode to a non-802.11ax or non-802.11gax mode removes the configuration.
Examples
# Enable TWT negotiation.

Usage guidelines
This command takes effect only on 802.11ax and 802.11gax radios. Changing the radio mode to 802.11a/b/g/n/ac/gac removes the configuration.
Uplink MU-MIMO enables an AP to receive data packets from multiple clients concurrently. With this feature enabled, an AP sends an HE_Trig message to all associated clients to inform the transmission time, frequency, sampling clock, and power requirements. Upon receiving the message, clients send data packets to the AP as required at the same time.
This feature is applicable to scenarios that have a large number of clients and high AP bandwidth usage and transmission latency requirements.
Only radios enabled with the client mode support this feature.
Examples
# Enable uplink MU-MIMO.
<Sysname> system-view
[Sysname] interface wlan-radio 1/0/2

OFDMA can provide the following benefits if enabled in a high density environment where small data packets are transmitted:
· Concurrent transmission to multiple users.
· Improved radio usage.
· Shortened transmission latency.
· Reduced conflict backoff.
