Checking the AP Status
Check Criteria
The AP health score is 100, the CPU usage does not exceed 90%, the memory usage does not exceed 80%, and the AP status is normal.
Procedure
- Log in to the web system, choose Monitoring > Summary, and check whether the AP health score is 100.
- Choose Monitoring > AP to check AP information.
If the AP health score is 100, check its CPU usage and memory usage.
If the AP health score is lower than 100, check the version, status, STA access failure ratio, STA going-offline ratio, number of STAs, CPU usage, and memory usage.
- Check the CPU usage and memory usage.
Check whether the CPU usage of the AP exceeds 90% and whether its memory usage exceeds 80%. If the CPU usage or memory usage is high, observe the CPU usage or memory usage for 5–10 minutes. If it remains high, record the CPU usage and memory usage data.
- Check AP version information.
Check whether the AP version matches the AC version. If not, upgrade the AP to a version matching the AC version by referring to the AP upgrade guide.
- Check the AP status.
Check whether the AP status displays as normal. Common AP states and corresponding handling suggestions are described as follows:
- normal: The AP is running properly, and no action is required.
- fault: The AP failed to go online. Check the network environment and AP onboarding configuration, and reconfigure the AP to go online.
- name-conflicted: Another AP with the same name has already gone online. Rename the current AP.
- ver-mismatch: The AP and AC versions do not match. Upgrade the AP to a version matching the AC version by referring to the AP upgrade guide.
- download: The AP is upgrading. Wait until the upgrade is complete.
- config: The AP is initializing the configuration. Wait until the initialization is complete.
- committing: The WLAN configuration is being delivered to the AP. Wait until the configuration delivery is complete.
- standby: This is the AP status displayed on the standby AC, and no action is required.
- countryCode-mismatch: The AP version does not support the country code configured on the AC. Upgrade the AP or modify the country code on the AC.
- If the AP is in another state or its state cannot restore to normal after you perform the preceding operations, collect network configuration information.
- Check the STA access failure ratio and logout ratio.
Check whether STA Access Failure Ratio and Logout Ratio values exceed 20%. If the STA access failure ratio or logout ratio exceeds 20%, record the values.
- Check the number of STAs.
Check whether more than 40 STAs connect to the same AP. More STAs connected to a single AP mean fewer resources for each STA and therefore deteriorated user experience. If more than 40 STAs associate with the same AP, user experience will deteriorate. In this case, reduce the maximum number of STAs that can associate with a VAP to deliver good experience to each user.
- Choose Diagnosis > Intelligent Diagnosis, select an AP, and start the diagnosis. Handle the problem found in the diagnosis according to the suggestions provided in the diagnostic result.
- If you suspect that the AP is faulty, contact your agent or Huawei global service hotline.
- If you need to quickly replace an AP while retaining the original AP configuration, perform the following steps:
- Replace the AP hardware.
- Log in to the web system and choose Configuration > AP Config > AP Config > AP Info. Select the AP to be replaced and click Replace.
- Enter the MAC address of the new AP in New AP MAC. Alternatively, click... at the end of New AP MAC, and select an AP in the dialog box that is displayed. Click OK. The model of the new AP must be the same as that of the original AP.
After the replacement, the new AP with the ID of the original AP re-associates with the AC and inherits all the data configured for the original AP.
- Seek technical support.
If the problem persists, contact your agent or Huawei global service hotline, and provide the fault information you have recorded to technical support personnel.
