Usage guidelines

You must enable radio resource measurement if you enable link, neighbor, or radio measurement.

You must enable spectrum management if you enable spectrum or TPC measurement. For more information about spectrum management, see Radio Resources Management Configuration Guide.

The spectrum and tpc keywords are available only for 5 GHz and 6 GHz radios.

Examples

# Enable spectrum measurement.‌

<Sysname> system-view

[Sysname] interface wlan-radio 1/0/1

[Sysname-WLAN-Radio1/0/1] measure spectrum enable

measure-duration

Use measure-duration to set the measurement duration.

Use undo measure-duration to restore the default.

Syntax

measure-duration time

Parameters

time: Specifies the measurement duration in the range of 1 to 10000 TUs. One TU is equal to 1024 microseconds.

Usage guidelines

When measurement is enabled on an AP, the AP adds the measurement duration in the measurement requests sent to clients.

Examples

# Set the measurement duration to 512 TUs.‌

<Sysname> system-view

[Sysname] interface wlan-radio 1/0/2

[Sysname-WLAN-Radio1/0/2] measure-duration 512

Related commands

measure

measure-interval

measure-interval

Use measure-interval to set the measurement interval for an AP to send measurement requests to clients.

Use undo measure-interval to restore the default.

Syntax

measure-interval interval

undo measure-interval

Default

The measurement interval is 30 seconds.‌

resource-measure

Use resource-measure enable to enable radio resource measurement.

Use resource-measure disable to disable radio resource measurement.

Use undo resource-measure to restore the default.

Syntax

resource-measure { disable | enable }

undo resource-measure

Default

Radio resource measurement is disabled.‌

Usage guidelines

When radio measurement is enabled on an AP, the AP sets the Radio Measurement field to 1 in beacons, probe responses, association responses, or reassociation responses. It notifies the clients that they can send measurement requests. These frames also carry measurement capabilities of the AP to inform clients of measurement types that the AP supports.

The AP periodically sends Measurement Pilot frames to help clients fast discover the AP. Measurement Pilot frames are sent more frequently than beacons and carry less information.

Examples

# Enable radio resource measurement.‌

<Sysname> system-view

[Sysname] interface wlan-radio 1/0/2

[Sysname-WLAN-Radio1/0/2] resource-measure enable

rm-capability mode

Use rm-capability mode to set the match mode for client radio resource measurement capabilities.

Use undo rm-capability mode to restore the default.

Syntax

rm-capability mode { all | none | partial }

undo rm-capability mode

Default

The match mode is none for client radio resource measurement capabilities.‌

Parameters

all: Specifies the all mode. A client is allowed to associate with an AP only when all its radio resource measurement capabilities match the AP's radio resource measurement capabilities.

none: Specifies the none mode. The AP does not check client radio resource measurement capabilities.

partial: Specifies the partial mode. A client is allowed to associate with an AP as long as one of its radio resource measurement capabilities matches any of the AP's radio resource measurement capabilities.

Usage guidelines

The configuration takes effect only when radio resource measurement is enabled.

Examples

# Set the match mode to partial for client radio resource measurement capabilities.‌

<Sysname> system-view

[Sysname] interface wlan-radio 1/0/2

[Sysname-WLAN-Radio1/0/2] rm-capability mode partial
