Configuring a Mesh Role and a Mesh Profile

Configuring a Mesh Role and a Mesh Profile

Context

On a vehicle-ground fast link handover network shown in Figure 16-8, Mesh roles of the vehicle-mounted AP and trackside AP are MP and MPP respectively.

Figure 16-8  Networking diagram of vehicle-ground fast link handovers

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    wlan

    The WLAN view is displayed.

  3. Run:

    ap-system-profile name profile-name

    The AP system profile view is displayed.

    By default, the system provides the AP system profile default.

  4. Run:

    mesh-role mesh-portal

    The Mesh role of the trackside AP is set to MPP.

    By default, the Mesh role of an AP is mesh-node in the AP system profile.

  5. Run:

    antenna-output { split | combine }

    The output mode of 2.4G/5G antennas is specified.

    By default, a 2.4G/5G antenna uses split output.

    Only the AP9132DN supports this function.

  6. Run:

    quit

    Return to the WLAN view.

  7. Run:

    mesh-profile name profile-name

    A Mesh profile is created, and the Mesh profile view is displayed.

    By default, the system provides the Mesh profile default.

  8. Run:

    mesh-id name

    A Mesh ID is configured. Mesh nodes use a Mesh ID to identify connections between them.

    By default, the Mesh ID of a Mesh profile is HUAWEI-WLAN-MESH.

  9. Run:

    security-profile profile-name

    A security profile is bound to the Mesh profile.

    By default, the security profile default-mesh is bound to a Mesh profile.

    NOTE:

    By default, the system provides the Mesh profile default. Both the default Mesh profile default and a self-defined Mesh profile have the security profile default-mesh referenced by default. In the security profile default-mesh, the security policy is set to WPA2+PSK+AES and the security key to huawei_secmesh. If the default security profile default-mesh is used, you are advised to change the security key of the profile to ensure security.

  10. (Optional) Improve channel usage efficiency.

    1. Run the beacon-2g-rate beacon-2g-rate command to set the transmit rate of 2.4 GHz Beacon frames.

      By default, the transmit rate of 2.4 GHz Beacon frames is 1 Mbit/s.

    2. Run the beacon-5g-rate beacon-5g-rate command to set the transmit rate of 5 GHz Beacon frames.

      By default, the transmit rate of 5 GHz Beacon frames is 6 Mbit/s.

  11. (Optional) Run:

    max-link-number link-num

    The maximum number of Mesh links allowed on an AP is configured.

    By default, a maximum of eight mesh links can be established between APs. After you enable FWA for a mesh profile using the fwa enable command, a maximum of 32 mesh links can be established between APs by default.

  12. (Optional) Run:

    link-rssi-threshold threshold-value

    The RSSI threshold of a Mesh link is configured. When the minimum RSSI of all Mesh links on the optimal route to the current MPP is lower than the RSSI threshold of a Mesh link, the MP reselects Mesh links.

    By default, the RSSI threshold of a mesh link is -75 dBm. After the FWA mode is enabled in a Mesh profile, the RSSI threshold of a Mesh link is fixed as -90 dBm.

  13. (Optional) Run:

    link-report-interval report-interval

    The interval at which an MP reports Mesh link information to an AC is specified.

    By default, an MP reports Mesh link information to the AC at an interval of 30 seconds.

  14. (Optional) Run:

    dhcp trust port

    A DHCP trusted port is enabled in the Mesh profile.

    By default, a DHCP trusted port is enabled in a Mesh profile.

    NOTE:

    After a DHCP trusted port is enabled in a Mesh profile and the Mesh profile is applied to an AP, the AP receives the DHCP OFFER, ACK, and NAK packets sent by authorized DHCP servers and forwards the packets to STAs so that the STAs can obtain valid IP addresses and go online.

  15. Run:

    quit

    Return to the WLAN view.

  16. Apply the Mesh profile. You can use any of the following methods according to actual situations:

    • Bind the Mesh profile to an AP group.

      1. Run the ap-group name group-name command to enter the AP group view.

      2. Run the mesh-profile profile-name radio { all | radio-id } command to bind the Mesh profile to the AP group.

        By default, no Mesh profile is bound to an AP group or AP.

        NOTE:
        A Mesh link uses the VAP with the WLAN ID 16, which cannot be occupied by other WLAN services.
    • Bind the Mesh profile to an AP.

      1. Run the ap-id ap-id, ap-mac ap-mac, or ap-name ap-name command to enter the AP view.
      2. Run the mesh-profile profile-name radio { all | radio-id } command to bind the Mesh profile to the AP.

        By default, no Mesh profile is bound to an AP group or AP.

        NOTE:
        A Mesh link uses the VAP with the WLAN ID 16, which cannot be occupied by other WLAN services.
    • Bind the Mesh profile to AP group radios.

      1. Run the ap-group name group-name command to enter the AP group view.
      2. Run the radio radio-id command to enter the radio view.
      3. Run the mesh-profile profile-name command to bind the Mesh profile to AP group radios.

        By default, no Mesh profile is bound to an AP radio.

        NOTE:
        A Mesh link uses the VAP with the WLAN ID 16, which cannot be occupied by other WLAN services.
    • Bind the Mesh profile to an AP radio.

      1. Run the ap-id ap-id, ap-mac ap-mac, or ap-name ap-name command to enter the AP view.
      2. Run the radio radio-id command to enter the radio view.
      3. Run the mesh-profile profile-name command to bind the Mesh profile to the AP radio.

        By default, no Mesh profile is bound to an AP radio.

        NOTE:
        A Mesh link uses the VAP with the WLAN ID 16, which cannot be occupied by other WLAN services.
