[Ques]Why did Switch reboot?

[dangkita]

Hi all,

I read some log from command:
"show log swlog "
and see that Switch rebooted at "THU SEP 06 04:00:26 2012"

Log like this:

Code: Select all

I want to know why switch rebooted.
Could it be possible?

Thanks,

power failure

From the log lines you posted, the reason for the issue can't really be predicted. What happened before?

[dangkita]

@one6f: why do you know the reason is hardware failure?
@benny: i'm not sure. Do we have any way to check why the switch reboots? i mean see the log file or another way to know the extractly reason.

[benny]

I suggest that you start the logging of your telnet/ssh session and post a file of your full "show log swlog" output.
