sta-load-balance dynamic rssi-diff-gap

sta-load-balance dynamic rssi-diff-gap

Function

The sta-load-balance dynamic rssi-diff-gap command sets the RSSI difference threshold of members in a dynamic load balancing group.

The undo sta-load-balance dynamic rssi-diff-gap command restores the default RSSI difference threshold of members in a dynamic load balancing group.

By default, the RSSI difference threshold of members in a dynamic load balancing group is 5 dB.

Only cloud APs support this command.

Format

sta-load-balance dynamic rssi-diff-gap diff-gap-threshold

undo sta-load-balance dynamic rssi-diff-gap

Parameters

Parameter

Description

Value

diff-gap-threshold

The value is an integer that ranges from 0 to 15, in dB.

Usage Guidelines

Usage Scenario

To achieve load balancing, an AP may migrate connected STAs to other APs with smaller RSSIs. If the RSSI of the AP with which a STA currently associates minus the RSSI of the target AP is larger than the specified RSSI difference threshold, the STA is denied from being migrated to the target AP; otherwise, the STA can be migrated to the target AP.

Precautions

If STAs have high signal quality deterioration tolerance for the target AP, you can set a larger RSSI difference threshold to achieve better load balancing effect. If STAs have low signal quality deterioration tolerance for the target AP, set a smaller RSSI difference threshold. You are advised to retain the default value.

This command is valid only in sta-number mode.

Example

# Set the RSSI difference threshold of members in a dynamic load balancing group to 6 dB in RRM profile default.
