reviewing crashfile for crashed switch - 3850

afsharki2 · ‎08-31-2016

hello everyone,

I have a stack of 3 3850s. Does anyone know how to review a crashfile for when a switch crashes. I cannot determine why the switch crashed, but it did leave behind a crashfile.

sh ver

Switch 1 uptime is 10 hours, 59 minutes
Uptime for this control processor is 11 hours, 6 minutes
System returned to ROM by Power Failure at 17:05:00 pdt Fri Jul 29 2016
System restarted at 23:34:15 pdt Tue Aug 30 2016
System image file is "flash:packages.conf"
Last reload reason: Power Failure

Last reload reason: Power Failure

It isn't due to a crash.

Post the complete output to the command "dir".

Yeah, I saw that. dir crashinfo did produce a crashinfo file. Will it produce the file even if there is a power outage?

I will get you the info when I get back. I've just seen a case where it said "power failure" but the actual switch had hardware problems where we ended up replacing it.

It shouldn't be a file but two sets of sub-directories. If date & time is correctly set then it will tell when the file(s) were created.

Kindly post the complete output to the command "dir".

Will it produce the file even if there is a power outage?

No.
