Function

The display channel switch-record command displays channel switching records on the device.

Format

display channel switch-record { all | calibrate | ap-name ap-name radio radio-id | ap-id ap-id radio radio-id | reason reason }

Parameters

Parameter Description Value
all

Displays all channel switching records.

-

calibrate

Displays channel switching records for radio calibration.

-

ap-name ap-name

Displays channel switching records of the RU with a specified name.

The RU name must exist.

radio radio-id

Displays channel switching records of a specified RU radio.

The radio ID must exist.

ap-id ap-id

Displays channel switching records of the RU with a specified ID.

The RU ID must exist.

reason reason

Displays records of channel switching caused by a specified reason.

The enumerated values are:
  • calibration: channel switching caused by radio calibration
  • configuration: channel switching caused by configuration
  • dfs: channel switching performed to avoid radar channels
  • mesh: channel switching caused by channel negotiation on a Mesh network
  • unsupported: channel switching performed because the RU does not support the channel delivered from the Central AP
  • wds: channel switching caused by channel negotiation on a WDS network
  • 3gpp-bs-notification: channel switching notified by a 3GPP base station.

Usage Guidelines

This command enables you to view channel switching records on a device.

Run the display channel switch-record calibrate command to query channel or power switching records caused by radio calibration to check the calibration results.

Description

AP ID

AP ID.

AP name

Name of an RU where channel switching has occurred.

RfID

Old/New

Channels used before and after switching.

Switch reason

Reason for channel switching.
  • calibration: channel switching caused by radio calibration
  • configuration: channel switching caused by configuration

Item Description

AP ID

AP ID.

AP name

AP name.

RfID

Radio ID.

PCH/CCH

Channels before and after calibration.

NOTE:
PCH/CCH changes may be discontinuous for a radio.

PBW/CBW

Bandwidth before and after calibration.

PE/CE

Power before and after calibration.

NOTE:
PE/CE changes may be discontinuous for a radio.

PR/CR

Interference values before and after calibration.

Reason

Reason for triggering calibration.

  • Period recheck: periodic calibration
  • Bad env: environment deterioration
  • Non-Wi-Fi report: non-Wi-Fi report
  • Rogue AP report: rogue ap report
  • Noise interfere: noise interfer
  • Global plan: trial operation
  • AP online: The AP radio is on, the radio is switched (between 2.4 GHz and 5 GHz bands), the radio working mode changes, or the AP goes online.
  • AP offline: The AP radio is off, the radio is switched (between 2.4 GHz and 5 GHz bands), the radio working mode changes, or the AP goes offline.
  • Unknown: unknown reason

Time

Time when calibration is triggered.

Trigger ID(Radio)

  • For a common central AP: ID of the AP (radio) that triggers partial radio calibration
  • For a cloud central AP: ID of the device (radio) that triggers partial radio calibration
NOTE:
If global radio calibration is triggered, this field displays -.
