Checking Whether APs Can Go Online

Checking Whether APs Can Go Online

Context

Before deploying APs onsite, complete network planning operations, for example, configure the AC and involved NEs, and add APs on the AC. After APs are connected to the network and powered on, they can automatically upgrade and go online. Users do not need to perform other configurations on the APs onsite.

You can check whether the APs go online properly on the AC as planned. If the AP status displays as normal, the APs have gone online properly.

Procedure

  • Run the display ap all command to check whether APs go online on an AC.

    AP state. For details, see Table 5-8.

    Table 5-8  AP state list

    AP State

    Description

    Possible Cause

    Handling Suggestion

    commit-failed

    WLAN service configurations fail to be delivered to an AP after the AP goes online on an AC.

    After the AP goes online on the AC, WLAN service configurations are performed for the AP. If the link between the AP and AC is disconnected or the peer end has no response, the AP enters the commit-failed state.

    Check the network connection.

    committing

    WLAN service configurations are being delivered to an AP after the AP goes online on an AC.

    After the AP goes online on the AC, WLAN service configurations are being delivered to the AP.

    This is a normal state, and no action is required.

    config

    WLAN service configurations are being delivered to an AP when the AP is going online on an AC.

    After the AP establishes a link with the AC, WLAN service configurations are delivered to the AP. During this process, the AP is in config state.

    This is a normal state, and no action is required.

    config-failed

    WLAN service configurations fail to be delivered to an AP when the AP is going online on an AC.

    After the AP establishes a link with the AC, WLAN service configurations are delivered to the AP. If the configuration delivery fails due to various reasons (such as link disconnection), the AP enters the config-failed state.

    Check the network connection.

    download

    An AP is in upgrade state.

    When the AP is performing an upgrade, it enters the download state.

    When the AP upgrade is complete, check the AP state.

    fault

    An AP fails to go online.

    The AP fails to go online, which is usually caused by the following:
    • The AP fails to obtain an IP address or obtains an incorrect IP address.
    • The network between the AP and AC is faulty.
    • The AP fails to be authenticated.
    • The number of APs on an AC has reached the maximum value.
    • The AP is faulty.

    Handle the AP online failure. For details, see AP Online Failure in the Troubleshooting Insights.

    idle

    It is the initialization state of an AP before it establishes a link with the AC for the first time.

    The AP has not established a CAPWAP link with the AC, the MAC address and SN of the AP that is added offline are different from the actual ones, or license resources are insufficient.

    Perform the following operations.

    Check whether the AP is connected to the network. If the AP connection is normal, go to next step.

    Check the MAC address and SN of the AP that is added offline are different from the actual MAC address and SN of the AP. If not, perform the following operations:
    1. Run the display ap all command to obtain AP information.
    2. Run the undo ap { ap-name ap-name | ap-id ap-id | ap-mac ap-mac | ap-group group-name | all } command to delete the AP.
    3. Run the

      ap-id ap-id [ type-id type-id | ap-type ap-type ] [ ap-mac ap-mac ] [ ap-sn ap-sn ]

      or ap-mac ap-mac [ type-id type-id | ap-type ap-type ] [ ap-id ap-id ] [ ap-sn ap-sn ] command to add correct AP information.

    If the fault persists, expand the license capacity. Note that RUs managed by the AC do not occupy license resources of the AC.

    name-conflicted

    The name of an AP conflicts with that of an existing AP.

    The name of an AP conflicts with the name of another AP that has been online on the same AC.

    Run the ap-rename ap-id ap-id new-name ap-new-name command to change the AP name.

    normal

    An AP is working properly.

    An AP successfully goes online on an AC.

    This is a normal state, and no action is required.

    standby

    The AP is in normal state on the standby AC.

    In the HSB, dual-link cold backup, or N+1 backup scenario, if the link between the active and standby ACs is established properly, the AP is in standby state on the standby AC and in normal state on the active AC.

    This is a normal state, and no action is required.

    ver-mismatch

    The version of an AP does not match that of an AC on which the AP is to go online.

    The versions of the AP and the AC mismatch.

    Log in to Huawei technical support website and download the release notes. Based on the version mapping, upgrade the AP or AC to the matching version.
