Configuring Smart Roaming
Pre-configuration Tasks
Before configuring smart roaming, perform the task of WLAN Service Configuration Guide.
In WDS and Mesh scenarios, scanning services are not supported. Functions dependent on neighboring scanning, such as load balancing, smart roaming, and band steering, cannot be used.
APs of different R software versions cannot establish CAPWAP links with each other. To ensure service experience of users in load balancing, smart roaming, and band steering, it is recommended that APs of the same version be used. If APs of different versions need to be deployed on the same network, do not deploy APs of different versions as neighbors to each other.
Procedure
- Run system-view
The system view is displayed.
- Run wlan
The WLAN view is displayed.
- Run rrm-profile name profile-name
The RRM profile view is displayed.
- Run undo smart-roam disable
Smart roaming is enabled.
By default, smart roaming is enabled.
- (Optional) Run undo smart-roam advanced-scan disable
The coordinated scanning function of smart roaming is enabled.
By default, the coordinated scanning function of smart roaming is enabled.
- (Optional) Run smart-roam roam-threshold { check-snr | check-rate } *
The trigger mode of smart roaming is configured.
By default, the trigger mode of smart roaming is check-snr.
- (Optional) Run smart-roam roam-threshold { snr snr-threshold | rate rate-threshold }
The smart roaming threshold is configured.
By default, the SNR threshold for smart roaming is 20 dB, and the rate threshold is 20%.
- (Optional) Run smart-roam snr-margin high-level-margin high-level-margin low-level-margin low-level-margin
The SNR difference threshold that triggers terminal roaming is configured.
By default, the higher and lower SNR difference thresholds that trigger terminal roaming is 15 dB and 6 dB, respectively.
- (Optional) Run smart-roam quick-kickoff-snr check-interval check-interval
The terminal SNR check interval is configured.
By default, the terminal SNR check interval is 500 ms.
- (Optional) Run smart-roam quick-kickoff-snr p-n criteria observe-time observe-value qualify-time qualify-value
The PN threshold for quickly disconnecting STAs is specified.
By default, the number of PN observation times is 6, and the number of PN observation times criteria are met is 4.
- (Optional) Run smart-roam unable-roam-client expire-time expire-time
The aging time of "unable to roam" record is configured for terminals.
By default, the aging time of "unable to roam" records is 120 minutes.
- (Optional) Run smart-roam quick-kickoff back-off-time back-off-time
The backoff time for quickly disconnecting STAs is set.
By default, the backoff time for quickly disconnecting STAs is 60 seconds.
- (Optional) Run sta-load-balance dynamic btm-fail-times btm-fail-times
The maximum number of attempts is set to steer STAs in BTM mode.
By default, the maximum number of attempts to steer STAs in BTM mode is 5.
- (Optional) Run sta-load-balance dynamic deauth-fail-times deauth-fail-times
The maximum number of attempts to steer STAs in deauthentication mode is set.
By default, the maximum number of attempts to steer STAs in deauthentication mode is 2.
- (Optional) Run sta-load-balance dynamic steer-restrict probe-threshold probe-threshold
The maximum number of times is set for non-target APs to suppress probing of STAs during STA steering.
By default, the maximum number of times non-target APs suppress probing of STAs during STA steering is 5.
- (Optional) Run sta-load-balance dynamic steer-restrict auth-threshold auth-threshold
The maximum number of times is set for non-target APs to suppress authentication of STAs during STA steering.
By default, the maximum number of times non-target APs suppress authentication of STAs during STA steering is 0.
- (Optional) Run sta-load-balance dynamic steer-restrict restrict-time restrict-time
The duration within which non-target APs suppress association of STAs during STA steering is set.
By default, the duration within which non-target APs suppress association of STAs during STA steering is 5 seconds.
- Run quit
Return to the WLAN view.
- Bind the RRM profile to a radio profile.
- Run the radio-2g-profile name profile-name or radio-5g-profile name profile-name command to enter the 2G or 5G radio profile view.
- Run the rrm-profile profile-name command to bind the RRM profile to the 2G or 5G radio profile.
- Run the quit command to return to the WLAN view.
- Bind the radio profile to an AP group or a specific AP. For the detailed procedure, see Binding a Radio Profile.
Verifying the Configuration
- Run the display rrm-profile name profile-name command to check settings of smart roaming parameters.
- Run the display radio-2g-profile name profile-name command to check the RRM profile referenced by a 2G radio profile.
- Run the display radio-5g-profile name profile-name command to check the RRM profile referenced by a 5G radio profile.
- Run the display station neighbor sta-mac mac-address command to check the neighbor list of a specified STA.
- Run the display station steer-history command to check historical steering information about a specified STA.
- Run the display station steer-statistics command to check STA steering statistics.
