smart-roam roam-threshold { check-snr | check-rate }

smart-roam roam-threshold { check-snr | check-rate }


The smart-roam roam-threshold { check-snr | check-rate } command configures the trigger mode of smart roaming.

The undo smart-roam roam-threshold command restores the default trigger mode of smart roaming.

By default, the trigger mode of smart roaming is check-snr.


smart-roam roam-threshold { check-snr | check-rate }*

undo smart-roam roam-threshold






Specifies the trigger mode of smart roaming as check SNR.



Specifies the trigger mode of smart roaming as check rate.

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.

Usage Guidelines

Usage Scenario

After the smart roaming function is enabled, the AP forces STAs to log out based on the configured trigger mode and threshold of smart roaming. When an AP receives a STA's data packet, the AP learns the STA's SNR or rate from the data packet. If the STA's SNR or rate is lower than the configured threshold, the AP sends a Disassociation frame to the STA so that the STA can reinitiate a connection with the AP or roam to another AP with strong signals.


The smart roaming function has been enabled using the undo smart-roam disable command.

Follow-up Procedure

Run the smart-roam roam-threshold { snr | rate } command to configure the smart roaming threshold.


# Set the trigger mode of smart roaming to check-rate.
