After the AP's Uplink Wired Interface Is Configured to Work in Endpoint Mode, the AP Cannot Go Online After a Restart

After the AP's Uplink Wired Interface Is Configured to Work in Endpoint Mode, the AP Cannot Go Online After a Restart

Fault Symptom

After the AP's uplink wired interface is configured to work in endpoint mode, the AP cannot go online after a restart.

Procedure

  1. Check whether the AP's uplink wired interface is configured to work in endpoint mode.

    Error-prone configuration:

    When working as an uplink interface to connect to an AC, an AP's wired interface must work in root mode. In root mode, the AP's wired interface automatically joins service VLANs and user-specific VLANs (for example, VLANs assigned by the RADIUS server).

    When working as a downlink interface to connect to a wired terminal, the AP's wired interface must work in endpoint mode. In endpoint mode, the AP's wired interface does not join any VLAN by default.

    NOTE:
    This configuration takes effect only after the AP is restarted.
    <HUAWEI> system-view
    [HUAWEI] wlan
    [HUAWEI-wlan-view] wired-port-profile name wired
    [HUAWEI-wlan-wired-port-wired] mode endpoint
    Warning: If the AP goes online through a wired port, the incorrect port mode configuration will cause the AP to go out of management. 
    This fault can be recovered only by modifying the configuration on the AP. Continue? [Y/N]:y
    [HUAWEI-wlan-wired-port-wired] return
    

    Suggestion:

    • Hold down the Default button to restore factory settings of the AP.
    • Log in to the AP and perform the following operations:
      1. Configure a static ARP entry on the access switch.
        <Switch> system-view 
        [Switch] arp static 169.254.1.1 a858-40dd-ef80  //The default IP address of the AP is 169.254.1.1. The MAC address of the AP is specified because devices on the network may have the same IP address.
      2. Configure an IP address on the same network segment as that of the AP for the switch.
        [Switch] interface Vlanif1
        [Switch-Vlanif1] ip address 169.254.1.100 255.255.255.0
        [Switch-Vlanif1] quit
      3. Configure the PVID for the port connecting the switch directly to the AP.
        [Switch] interface GigabitEthernet0/0/1
        [Switch-GigabitEthernet0/0/1] port trunk pvid vlan 1
      4. Log in to the AP from the access switch through STelnet.
      5. Run the work-mode root command in the interface view of the AP to set the working mode of the interface to root. Alternatively, run the reset factory-configuration command in the user view to restore factory settings of the AP.
        <Huawei> system-view 
        [Huawei] interface GigabitEthernet 0/0/0                                         
        [Huawei-GigabitEthernet0/0/0] work-mode root
      6. Restart the AP.
        <Huawei> reboot
