How to check the issue during apply the configuration file?
If a user cannot apply a configuration file and the device shows an error log, choose "Immediately stop applying the configure file" first before trying to apply the configuration file.
Go to Monitor > Log > Display category, choose "File Manager"; or use the command "show logging entries category file-manage".
This displays detailed information about errors encountered when applying the configuration file. Refer to the information and make the correction.
Below is a sample that shows the configuration file has duplicated settings and has an incomplete static DHCP address so that the device can't apply it.
