Issue Description

We found that one AR152 was offline on the eSight, but the AR152 did not find the log information.

Solution

As you can see, the device rebooted by power off but not “reboot” command.

========================================================

 ===============display reset-reason===============

========================================================

TheMPU frame[0] board[0]'s reset total 1, detailed information:

-- 1. 01/24  09:27:05, Reset No.: 1

      Reason: Board have been pulled out or no power

 

For the AR box device, since the flash card size is small, so all the logs will write in device buffer first, once buffer is full, then will compress in flashcard.

Onceit power off then the logs which in buffer will disappear,

But if device reboot by command, logs will not disappear, will store in device flash card auto.

 

So as you can see the logs on Jan/24/2019 after device power on for GE0/0/0 LINKDOWN, logs showing as follow
