  Rewarded Hi-coins: 0 (problem resolved)

we have a s5720li as a access switch and it worked fine before, but today some users who access to this this switch reported that cannot access the internet, I checked the switch and found that the configuration was gone, I have to reconfigure it, after that, the users could access the internet successfully. The s5720li seems work fine.

I want to know how to check the problem which caused the configurations gone, cause I don’t want to reconfigure it once again.

appreciate for any suggestions.

Hi!
 
From the output, we could learn that the device was rebooted at 02:19:56 2019/05/29.

You should check the power supply system, I think you configured the switch and without saving the configuration; so, when the switch rebooted, the unsaved configuration was lost.

I noticed that the switch uptime is only 1 day, but you said the switch has worked fine for a couple of month, so I think you should check the reboot information, if the switch reboot before.
please excute command display reboot-info to check that information.
