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.
Usage guidelines
This command is applicable only to 802.11n, 802.11ac, and 802.11gac 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
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, and 802.11gac 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.

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.
