CatOS 6.4(5a) 'show log' - "Re-boot History" vs. "Last software reset by"

[a.manosca]

[Catalyst 6009, Sup 1A, X6348 Ethernet modules]

Should the "Re-boot History" (the latest log was Oct 26 2003 17:58:54) and "Last software reset by user:" (8/17/2003,14:19:24) dates be the same? I think the switch re-booted itself last Oct. 26, 2003 but unfortunately we were not able to get the logs. If it did, is there any other way to determine the cause without the logs?

Here's the output of the 'show log'

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

I'm trying to find a documentation about this but haven't found one yet. Any help is greatly appreciated.

Thanks.

Found one tech note from CCO:

http://www.cisco.com/en/US/products/hw/switches/ps700/products_tech_note09186a008015504b.shtml#subtopic4b

Here's the info:

"...The above show log command output displays no software exceptions, and that the last reboot of the switch is Jan 06 2003. From the last software reset field, you can see that the reboot time matches.

The show log command output below shows an exception recorded at the time of the last reboot. If your switch shows such a software exception, open a TAC case with the output of the show tech and show log command outputs. A TAC engineer will be able to identify the reason for the crash."

So what if the dates don't match and there are no Exceptions?

Nope, not necessarily. Last reset from user is a legitimate reset from the command line. The last reboot reported in show log can be from any kind of reset - crash, power outage, etc.

If you suspect that the switch crashed and there is a valid stack from the show log output, then open a TAC case to have it analyzed. Please also include in the case show tech and show logging buffer 1023.
