With automatic bandwidth adjustment enabled, the AP starts channel quality detection when the automatic bandwidth adjustment interval is reached, and determines whether to perform bandwidth adjustment. It decreases the bandwidth for a radio to reduce interference if the number of neighbor radios for that radio is large, and increases the bandwidth to increase transmission rate if the number is small.

This command takes effect only on 5 GHz and 6 GHz radios.

Usage guidelines

With radar detection enabled, if an AP detects a radar signal on the current channel, it either switch the channel or go silent to prevent radar interference. However, the new channel might lead to a degraded wireless network experience due to high interference or other issues. In such cases, you can enable radar detection-triggered RRM. After an AP detects radar signals and switches the channel, it notifies RRM to evaluate the new channel for further adjustments. If necessary, RRM automatically adjusts the channel to improve wireless network quality.

Parameters

neighbor: Specifies the adjacency factor in the range of 1 to 16.

Usage guidelines

The adjacency factor defines the quantity of manageable detected radios that trigger TPC and the ranking of the RSSI used for comparison with the power adjustment threshold. An AP can manage only radios associated with it.

For example, if the adjacency factor is 3, the AP performs TPC for a radio when the radio detects 3 other manageable radios. After ranking the radio's RSSIs detected by other manageable radios in descending order, the AP selects the third largest RSSI to compare with the power adjustment threshold.

Use wlan rrm calibration-channel ap to perform on-demand DFS for radios of the specified AP.

Syntax

wlan rrm calibration-channel ap name ap-name [ radio radio-id ] [ force ]

Views

System view

Predefined user roles

network-admin

Parameters

name ap-name: Specifies an AP by its name. The name can only be fatap.

radio radio-id: Specifies a radio by its ID. The value range for the radio-id argument varies by AP model. If you do not specify this option, the command takes effect on all radios of the specified AP.

force: Changes the working channel forcibly. If you do not specify this keyword, the AP determines whether to change the working channel based on the condition of the current working channel.

Usage guidelines

If you perform on-demand DFS for multiple radios, the calibration of one radio does not affect channel calibration of the other radios.

If you specify the force keyword, the new channel might not be the optimal channel.

The system will take a few minutes to scan channels and collect channel data. This might cause packet loss. During the calibration process, do not disable the radios or change channel scanning or WLAN RRM settings.

Examples

# Perform forced on-demand DFS for radio 1.
