display ap online-fail-record
Usage Guidelines
If an AP fails to go online on the AC, you can run this command to check the failure reason, which helps locate the fault.
After the number of AP online failure records reaches the maximum that can be stored, new records overwrite existing ones.
Example
# Display online failure records about the AP with the MAC address 1047-80b1-56a0.
<AC6605> display ap online-fail-record mac 1047-80b1-56a0

Reason Why an AP Fails to Go Online |
Suggestion |
|---|---|
Insufficient license resources. |
Expand the license capacity. Note that RUs do not occupy license resources of the AC. Huawei's Electronic Software Delivery Platform (ESDP) is accessible from the Internet and Huawei intranet.
|
The AP is not in the SN whitelist. |
Run the ap whitelist sn ap-sn1 [ to ap-sn2 ] command to add the AP to the whitelist or run the ap-confirm command to enable the AP to pass authentication. |
The AP is not in the MAC whitelist. |
Run the ap whitelist mac ap-mac1 [ to ap-mac2 ] command to add the AP to the whitelist or run the ap-confirm command to enable the AP to pass authentication. |
The AP is added to the AP blacklist. |
Check whether the AP needs to be added to the blacklist. To delete the AP from the blacklist, run the undo ap blacklist command. |
The MAC address and SN of the AP do not match. |
Check whether the MAC address and SN of the AP match. |
DTLS negotiation for CAPWAP tunnel setup fails. |
Check whether the PSK used for DTLS encryption is correctly configured. |
DTLS negotiation failed, because of negotiation timeout or inconsistent PSKs on two ends. |
|
CAPWAP tunnel negotiation fails. |
Check whether the network connectivity is normal. If yes, contact technical support personnel. |
APs cannot go online during data backup. |
Wait until backup is complete. |
The upgrade fails. |
Run the display ap update configuration command to check whether the AP's upgrade file is correct. If so, rectify the fault by referring to FIT AP Upgrade Fails. |
The CAPWAP tunnel fails to be established. |
Check whether the network connectivity is normal. If yes, contact technical support personnel. |
The configuration fails to be delivered. |
The device attempts to deliver the configuration again. If the failure persists, contact technical support personnel. |
The versions of the AP and AC do not match. |
Log in to http://support.huawei.com/enterprise and download the release notes. Based on the version mapping, upgrade the AP or AC to the matching version.
|
|
Replace the AP with that supported by the AC or replace the AC with one that supports this AP type. |
The AP name conflicts. |
Run the ap-rename command to rename the AP. |
The number of central APs reaches the upper limit. |
Check whether the number of central APs reaches the maximum value. |
The number of common APs reaches the upper limit. |
Check whether the number of common APs reaches the maximum value. |
The central AP is not in normal state. |
Run the display ap command to check the central AP status and take measures accordingly. |
The CAPWAP sensitive-info PSK is different on the two ends of the CAPWAP tunnel. |
Ensure that the PSK for encrypting CAPWAP sensitive information is the same on the AP and AC. Alternatively, enable the AP to set up a DTLS session with the AC using the default PSK. |
The CAPWAP integrity-check PSK is different on the two ends of the CAPWAP tunnel. |
Ensure that the PSK for checking CAPWAP packet integrity is the same on the AP and AC. Alternatively, enable the AP to set up a DTLS session with the AC using the default PSK. |
The configured and reported AP types are different. The real AP type is XXXX. NOTE:
If an AP has been deleted using the undo ap command, the AP type cannot be obtained. In this case, the AP online failure is displayed as The configured and reported AP types are different.. |
Ensure that the configured AP type is the same as the reported one. |
The AC license is not active. |
Activate the AC license. |
Too many APs go online concurrently, leading to a failure to create sufficient DBSS interfaces. |
No action is required. The APs will attempt to go online again. |
The country codes of the AP and AC are inconsistent, and the country code of the AP is locked. |
Configure the country code on the AC to be the same as that on the AP. The country code on some AP models cannot be modified. For example, the AP model with the suffix -US is used only in the United States, and its country code is fixed as US. |
Reset for the AC mode switching. |
No action is required. |
The WAC license expires. |
Purchase a new license and load it to the Agile Controller-Campus. |
The device has been disconnected from the Agile Controller-Campus for more than 90 days. |
Verify the Agile Controller-Campus address configured on the AC, and check network connectivity. |
The device is deleted from the Agile Controller-Campus. |
No action is required. |
The Agile Controller-Campus does not deliver AP information. |
|
Configuration synchronization is in progress, leading to the system busy. |
No action is required. |
| The IP version of this AP does not match. | Run the ap ip version command to modify the IP version of the AP or assign an IP address with a different version to the AP. |
| Backing up HA data. | Wait till HA data backup ends. |
| Insufficient LPU resources. | All the resources of the card are occupied. Go online through another card. |
| Invalid port on the switch connected to the AP. | Check whether a card does not support AP access or the cards are in different working groups. |
| Insufficient trunk resources. | The trunk resources are released. |
| The number of distribute APs reaches the upper limit of the central AP. | Re-plan the network and expand the network capacity by adding central APs. |
| The number of CAPWAP tunnels reaches the upper limit. | Properly allocate CAPWAP resources. |
