Upgrade the AP version individually through APDB

Traditional network. 

AC —— AP

By default, AC and AP versions are released together, and the current network environment also requires the same AC and AP versions. When AC decompresses the ipe file, it will also decompress the AP"s ipe and store it in the apimge folder by default. When AP goes online, it will download the ipe file in the apimge folder by default. However, if there are some special requirements, it may be required that the AP be upgraded to a version that is inconsistent with the AC version. In this case, the following operations are required.

Take upgrading WA7539 to E2605P51 as an example:

1. Get the AP"s separate ipe file, change the name to wa7500.ipe, and confirm the version number

2. Upload the AP ipe file to the root directory of the AC

Configure on AC

[AC]wlan image-load filepath local //Specify the AP to obtain the ipe file from the AC root directory
[AC]wlan apdb WA7539 Ver.A E2605P51 //Specify the version number of the AP to download the ipe file. Please check the version number name carefully. If the name is written incorrectly, the version download will fail.

3. Check whether the automatic version upgrade function is enabled (enabled by default)

firmware-upgrade disable //Check whether the configuration exists. If it exists, delete it first

If it is a dual-link backup and there is a standby AC, please note that the standby AC also needs to perform steps 1-3 above, otherwise the AP cannot be upgraded successfully. If it is an IRF network, you also need to upload the AP version file on the standby AC

4. Restart the AP upgrade when the service is idle

It is recommended to find an AP to manually reset and restart

<AC>reset wlan ap name xxx

After the restart is complete, dis wlan ap name XXX ver to check whether the S/W version AP version is successfully upgraded.

<AC>dis wlan ap name xxx verbose
S/W version : E2605P51 //New version after upgrade, upgrade successful
If the upgrade is successful, restart all APs of the same model
<AC>reset wlan ap model WA7539
Select a few APs again to check whether the versions are successfully upgraded
<AC>dis wlan ap name xxx verbose
S/W version : E2605P51 //New version after upgrade, upgrade successful

Additional note: The above steps are similar for different AP models, except that the device model, ipe file name and version number may need to be modified.

1. Be sure to upload AP ipe to the AC root directory, not to the apimge file. Otherwise, the AC will re-decompress the AP ipe after restarting, and overwrite the separately uploaded ap ipe file by default in apimge, causing the AP to be unable to go online

2. The AP ipe file must be uploaded to the AC root directory and wlan image-load filepath local must be configured together, neither of which can be missing

3. After restarting the AP, be sure to check whether the AP version has been successfully upgraded through the command line

4. The APDB function is usually only a temporary means to solve certain problems. Be sure to recycle the APDB function in time after the subsequent problems are solved. For example, when upgrading the unified version of AC and AP again, delete the AP ipe file in the AC root directory and delete the configuration on the AC to ensure that the AP downloads the same version as the AC.

[AC]wlan image-load filepath local //Delete
[AC]wlan apdb WA7539 Ver.A E2605P51 //Delete

If APDB is not recovered and deleted in time, the AC and AP will run inconsistently for a long time, and the version span may be too large, which may cause business abnormalities.

When recovering the APDB configuration, please note that the primary and standby ACs must be recovered together.
