Roaming Use Precautions

  • The APs on which WLAN roaming is implemented must use the same SSID and security profiles, and the security profiles must have the same configurations.
  • In direct forwarding mode, if the ARP entry of a user is not aged out in time on the access device connected to the AP after the user roams, services of the user will be temporarily interrupted. You are advised to enable STA address learning on the AC. After the function is enabled, the AP will send a gratuitous ARP packet to the access device so that the access device can update ARP entries in a timely manner. This ensures nonstop service transmission during user roaming.

    You can use either of the following methods to enable STA address learning according to the version of your product:
    • run the learn client ip-address enable command in the service set view.
  • IEEE 802.11r supports open system, WPA2-PSK, and 802.1x authentication.
  • The 802.11r fast roaming and Protected Management Frame (PMF) functions are mutually exclusive. If the 802.11r fast roaming function has been configured, the PMF function cannot be configured.
  • STAs that are not compatible with 802.11r cannot associate with WLANs on which the 802.11 fast roaming function is enabled. To guarantee normal network services for users, replace the earlier STA model with the one that supports 802.11r, or create two VAPs using the same SSID with one enabling 802.11r and the other disabling it, and retain other configurations.
  • When 802.1x authentication is used for 802.11r, some STAs may get offline and online again during reauthentication due to compatibility issues if 802.1x reauthentication is enabled.
