smart-roam quick-kickoff-threshold

Function

The smart-roam quick-kickoff-threshold command sets the threshold for quickly disconnecting STAs.

The undo smart-roam quick-kickoff-threshold command restores the default threshold for quickly disconnecting STAs.

By default, the SNR-based threshold for quickly disconnecting STAs is 15 dB, and the rate-based threshold is 20%.

Format

smart-roam quick-kickoff-threshold { snr snr-threshold | rate rate-threshold }

undo smart-roam quick-kickoff-threshold { snr | rate }

Parameters

Parameter	Description	Value
snr snr-threshold	Specifies the SNR-based threshold for quickly disconnecting STAs.	The value is an integer that ranges from 5 to 45, in dB.
rate rate-threshold	Specifies the rate-based threshold for quickly disconnecting STAs. The rate here refers to the negotiated rate based on the protocol and signal strength when a STA associates with an AP, instead of the actual rate of the STA.	The value is an integer that ranges from 1 to 100, in percentage.

Parameter

Usage Guidelines

Usage Scenario

After the function of quickly disconnecting STAs is enabled and the threshold for quickly disconnecting STAs is specified for an AP using this command, the AP acquires a STA's SNR or rate from data packets sent from the STA. If the STA's SNR or rate is lower than the specified threshold, the AP forcibly disconnects the STA so that the STA can reinitiate a connection with the AP or roam to another AP with strong signals.

A large threshold may cause STAs to go offline frequently.
A small threshold may disable STAs from roaming to an AP with stronger signals.

This command is applicable to scenarios that have high requirements on real-time transmission, such as voice and video scenarios.

Prerequisites

The function of quickly disconnecting STAs has been enabled using the undo smart-roam quick-kickoff-threshold disable command.

The mode for triggering the function of quickly disconnecting STAs has been set using the smart-roam quick-kickoff-threshold { check-snr | check-rate } command.

Precautions

STAs may be forced to go offline through the smart roaming function or the function of quickly disconnecting STAs. If the SNR-based thresholds for the two functions are both configured, the function with a larger value is preferentially effective.

Example

# Set the mode for triggering the function of quickly disconnecting STAs to check-snr and the threshold for quickly disconnecting STAs to 20 dB.
