Usage Guidelines

When you use commands on the AC to restart an AP manually, during an upgrade, or to restore its factory settings, the restart message delivered by the AC may get lost due to transmission failures. Therefore, APs are not restarted. If an AP does not receive the restart message, the AP is still connected to the AC, which makes the AC incorrectly consider that the AP is restarted successfully. This command displays records about AP restart failures, helping you check whether the AP is restarted successfully. If the AP restart fails, restart the AP.

Example
