rf-ping

Function

The rf-ping command enables an AP to automatically detect wireless link quality.

Format

rf-ping [ -m time | -c number ] [ -p { be | bk | vi | vo }] ^* mac-address

Parameters

Parameter	Description	Value
-m time	Specifies the interval for sending probe data packets.	The value is an integer that ranges from 100 to 10000, in milliseconds. The default value is 100.
-c number	Specifies the number of probe data packets sent by the AP.	The value is an integer that ranges from 1 to 1000. The default value is 10.
-p { be \| bk \| vi \| vo }	Specifies the priority of probe data packets sent by the AP, which can be AC_BE, AC_BK, AC_VI, or AC_VO. If this parameter is not specified, the default priority is AC_BK.	-
mac-address	MAC address of a STA.	The value is in H-H-H format. An H is a hexadecimal number of 4 digits.

Usage Guidelines

Use Scenario

This command allows an AP to automatically detect wireless link quality based on link parameters, including the signal strength, data rate on air port, and delay in packet transmission.

Prerequisites

STAs have been associated with the APs and go online.

Example

# Configure an AP to automatically detect quality of the link between the AP and STA with the MAC address 14cf-9202-13dc.
