In WLAN system, some stations(old device) have issue with roaming, for example: the station far away the old AP and the signal very weak, there have new AP and signal very strong, but the station don't roaming to the new AP. In Huawei WLAN system, we can configure smart roaming help station roaming.
Configure smart roaming.
# Create the RRM profile wlan-rrm, enable smart roaming in the RRM profile, configure SNR-based and rate-based roaming trigger modes and their roaming thresholds to 30 dB and 30%, respectively.
